Slutty Brownies

Happy Hump Day! I know I’ve posted about these slutty brownies before… but I just made a video to go along with them and thought it would be fun to share!

Happy brownie making :)

A few weeks ago I was perusing the interwebs, mainly pinterest, because it’s my latest obsession and I spend an inordinate amount of time pinning things that I want to eat, and things that I want at my wedding. I’m not quite sure how people planned weddings before Pinterest. It’s kinda the greatest invention of all times. But while I was knee deep in my wedding pinning extravaganza, I stumbled across something called Slutty Brownies.

Clearly these caught my attention immediately. They are the brilliant creation of The Londoner, who is just pretty much awesome. Basically it’s a super brownie made with layers of cookie dough, oreo cookies, and then a rich and decadent brownie layer. They are totally slutty brownies. Or I guess they could easily be “I just got dumped brownies.”

So basically after I found these I made them approximately 23 times. Okay so maybe it was 12 times, but the moral of the story is that these are just downright awesome. My fabulous friend Koko and I decided that these are best eaten by oneself, with a spoon, perhaps a glass of bubbly rose and some trashy TV (I recommend the Real Housewives of Beverly Hills or Shameless). They are decadent. One small bite will be enough to satisfy any sweet tooth.

You could easily make these with box mix, which is what the original recipe I found calls for, but I took it one step further and made these with my all time favorite rich chocolatly brownie recipe and my favorite chocolate chip cookie dough recipe. The oreo in the middle may seem slightly out of place because you might think it’s going to be this crunchy layer between two super soft and chewy layers, but let me reassure you that it’s not. The oreo kind of soaks up a bit of moisture from the brownie batter and cookie dough and just adds that extra bit of fabulousness.


So basically you’ve got to make these. They will change your life. The first 2 times I made these, I cut them right away to serve them and they kinda fell apart a bit since they were still crazy warm, and that’s totally one way to go. If you’re serving them fresh out of the oven, add a scoop of vanilla ice cream just for another layer of decadence and serve away. If you’re going to let them sit for a few hours, you’ll get a super gorgeous cut square and can grab it and go. Either way, they are awesome.

Slutty Brownies

Yield: 1 9x9 brownie pan

Serving Size: 16 brownies per recipe

Slutty Brownies


    For the Brownie layer:
  • 10 tbsp unsalted butter
  • 1 1/4 cups white sugar
  • 3/4 cup cocoa powder
  • 1/2 tsp salt
  • 2 tsp vanilla extract
  • 2 large eggs
  • 1/2 cup AP flour
  • For the Oreo layer:
  • 1 package of Oreo (regular stuffed or double stuffed)
  • For the Cookie Dough layer:
  • 1/2 cup unsalted butter (at room temp)
  • 1/4 cup brown sugar
  • 3/4 cup white sugar
  • 1 egg
  • 1 1/4 tsp vanilla extract
  • 1 1/4 cups AP flour
  • 1/2 tsp salt
  • 1/2 tsp baking soda
  • 1/2 tsp baking powder
  • 1 cup semi-sweet chocolate chips


  1. For the Brownie layer:
  2. In a medium sauce pan, melt the butter over medium high heat. Add the sugar and cocoa powder once the butter is melted. Whisk to combine and remove from heat. Add the salt, vanilla and eggs and continuously whisk until the eggs are combined. Add the flour and continue to mix. Set batter aside.
  3. For the Cookie Dough layer:
  4. Cream together the butter and sugars in a mixer. Add the eggs and vanilla, making sure to scrape down the sides of the mixing bowl. Add the flour, salt, baking soda and baking powder and mix on low until everything is incorporated. Fold in the chocolate chips. Set dough aside.
  5. Assembly:
  6. Pre-heat the oven to 350 degrees.
  7. Line the bottom of a 9x9 baking pan with tin foil and then spray the tin foil with a layer of baking spray.
  8. Layer the cookie dough on the bottom of a 9x9 baking pan, pressing down to form the bottom of the slutty brownies.
  9. Layer as many oreos that will fit on top of the cookie dough. No need to overlap. One single layer will do.
  10. Pour the brownie batter on top of the oreo layer and make sure it's evenly layers on top.
  11. Bake for 30-35 minutes. Test with a knife to see if the center is done. If the knife comes out clean, let the brownies rest before serving. If the knife comes out with batter still on it, allow the brownies to bake about 5 minutes more.
  12. Serve with ice cream :)


Don't know what to make,
or how to make it?
I've got you covered! Check out all my recipes here

  1. Holy wow, these look freaking delicious!! I love the combination of sinful ingredients in this that makes a slutty brownie haha..these are so dangerous, I’m sure I’d eat at least 3 or 4..

  2. I can’t think of enough adjectives to describe how these look! I would like to try one immediately!

  3. The only thing more dangerous right now than Pinterest, is this recipe! Like you, I’ve been spending way too much time pinning things to my virtual pin boards. These brownies…oh. w.o.w.

    1. They are great with Peanut butter cups, or Double stuff Oreo.!!! and the cookies that have the marshmallows on the top of them !!

  4. These looks ridiculous. These totally should come with a warning like “will cause tightening of jeans”. I am druelling just thinking about these

  5. Slutty indeed – feel very sick just looking at the recipe for this over the top sweet creation – there’s a dessert at Cecconi’s which has caramel and chocolate that the kids call the Delicious Yummy – one bite is all you need and even Remy can’t have more than two or three – this kinda reminds me of that!

  6. OK. Stupid question, for the browning mixture. Your refer to the sugar as ‘white sugar’ so you mean regular granulated sugar? Or “confectioners” sugar which is white?? Just want to clarify…so this can be made correctly. Thank you. :o)

  7. As I looked at this recipe the Other Half came up and looked over my shoulder and asked me when I was making this – so awesome, this will get added to my “make-soon-to-keep-him-happy” list :-)

  8. Dang, it’s like they’re not even *trying* to hold it all in. What is the world coming to? ;)
    No, really, I’m just bitter because I’m gluten free and can’t make these. At least not without some extra work.

  9. I saw this this morning and made them today…had to make them today! They are sooooo good, thank you. One thing? I am at 5000 feet so baking is always a bit of guesswork. I usually add some flour and things work fine but this time I tried it as written. They were perfect! But…they took much longer to bake? At 30 minutes the knife was till gooey so I added 7 min. Still gooey so I added 7 more. Still gooey so I added 5 more. Now the tops are nice and firm and the insides still tender and moist? 19 minutes longer?

    1. The same thing happened to mine. I kept adding 5 more minutes each time because the knife kept coming out gooey, so it was more like a total of 50 minutes. I didn’t get to try one though to know how they were since I sent them back to school with my son.

    2. I’m so glad i read this. Mine have currently been in the oven for about 40mins and still totally goey. Was starting to think I’de never taste.

  10. *THUMP*
    That was me passing out from the thought of this sinful dessert. These are all kinds of wrong girl!!!

  11. Wowza. I need these in my life, immediately. If only I’d known about them when I went through the worst break-up of my life this past summer…although maybe it’s a good thing that I didn’t…I surely would have eaten the entire pan! Can’t wait to make these!

  12. That looks delicious! I want to try a version using only the cookies from the oreo with my own buttercream frosting. Have you tried something like that?

  13. I needed an ooey-gooey dessert to make for the fellas who have been helping me out at work. This is definitely it!! They look incredible. Double batch you say? I think so! ;)

  14. THE best brownies in the entire world!!! PS I think the link back to me goes to The Londoner. PPS I want one of these tomorrow. I actually dream about these. I ate at least half the pan.

  15. In the interest of saving time because I have to make salted caramel brownies and cookies tonight too, I was wondering if I could use a brownie mix instead of making the brownie batter from scratch. Think it would work the same?

  16. I made some this weekend! Thanks for sharing! They were amazing and my son renamed then “super awesomest ultimate brownie”, wouldn’t want him calling them slutty!

  17. Hi ! I am a French cookblog girl and I just want to say : your recipe looks amazing ! One of the best brownie I have ever seen, I want to try it for my boyfriend, for sure I will become the love of his life with this kind of bakery !

  18. I made these this eve and added chopped pecan to the top. Oh dear lord!!! Remind me not to make these while pregnant again!

  19. OMG…this has to be one of THE most decadent desserts I have ever tasted!!! Very naughty but so so good!
    I have made them for a party tomorrow night but made an extra individual one as there was some brownie mixture left over…!!!!!

  20. My friend made these today and have to say….. Best brownies i have ever had nothing compares to these brownies…

  21. Thank you SO much for an alternative to the box-mix-topped version that’s floating around everywhere! I made these this afternoon and they are amazing.

  22. Can’t wait to try these! I wish you had the print with photo option – doesn’t do it justice to print it without that amazing picture! Thanks for the recipe!

  23. I know this may seem like a stretch, but I wonder if there is any way to make these a vegan treat without tasting off. With some sandwich cookies being vegan, it could be a fun recipe to experiment with! Thanks for the recipe!

    1. Lura, I was thinking the same thing…they were really tasty, but it was a whole lot of butter. I’m thinking of making them again with half the vegan choc chip cookies recipe from Chow ( and the vegan brownie recipe from Chow ( Anyway Oreos are vegan.
      Will try and keep you posted!
      Also, for some reason when I made these, the choc chip cookie batter bubbled up in between the Oreos–the brownies looked more marbled than layered!

  24. a couple of things: i am a serious chocoholic, brownies are my fav dessert, i love oreo double stuff cookies and choc chip cookies. I made this and it is FANTASTIC! it’s rich and you can’t eat more than a couple of tablespoons, but it is delish. Make it for your superbowl party, everyone is going to love.

  25. I made these last night but I added caramel because it came in the brownie box mix. I also added the extra oil & water suggested but I think I added too much of each. The end result? Uhm, the BEST ooey gooey brownies EVER! I cooked them for 45 minutes and they were still gooey, so that’s how they went to the Mom’s Night Out party I went too. They loved them. So I think I will continue to add too much water & oil and serve warm with ice cream. Thanks for the idea, They were great and different from the normal desserts I bring to parties. YUM! :-)

  26. here in pittsburgh we have a tradition at weddings called a ‘cookie table’. a table is set up near the coffee urn that is covered in cookies that the grandmothers, mothers, aunts, and anyone else who is enlisted makes and brings cookies (even if it’s a catered affair). cookie tables are found at wedding/baby showers, anniversaries and other parties. these would be a big hit on a cookie table!

  27. I made these for a school event and was asked for the recipe by 2 people. They were delicious even though I think I overbaked them and they were difficult to cut. I think they were supposed to be gooey, but they still had a great rich flavor. So decadent!

  28. Oh, my….love the name as well as the post-partum brownies moniker, these WILL be made today. Dang, through one of your links I found another Californian who’s a pastry chef. Can’t remember her name nor site, grrrr.. Will ‘pin’ this. wish i knew how to use those boards, or save blog posts without overloading my desktop, lol. (pc, aka mad scientist in the kitchen)

  29. I have seen this recipe pop up on Tasty Kitchen and every time, my mouth waters. I still haven’t tried it because they look so addicting, I’d probably make them 23 times (or more) too. I like that you made the full recipe (except for the oreos, of course) from scratch – this adds a sweeter and more personalized spin. Looks great!

  30. I made these Friday night. . .1. best Friday night activity in a long time, 2. best eating Friday night activity in a long time. When I finally decided to share them, everybody loved them. Thank you for the recipe. I’m looking forward to baking the leftover cookie dough!

  31. Jessica Simpson was just on Jay Leno and stated that her new pregnancy craving is the “Slutty Brownie”.
    Cookie dough, oreas and brownies. Wow, I am making these tomorrow!!!! Can’t wait!

  32. They look luscious. Passing recipe to local coffee hangout with a creative baker. Hoping to try them out shortly. It would be suiscide for me to try to make them at home!

  33. Do you think they would taste as good if I used store bought cookie dough? I have a 2 year old and I’m trying to save some time. Can’t wait to try these!!

  34. I love this recipe and all the other brownie recipes you have shared! :)) Love Ree and her southern hospitality!

  35. Can’t wait to delight the masses! One question – how do you get 10 equally sized brownies from a 9×9 pan?

  36. My mother has forbidden my from makeing these…I’m supposed to be dieting. Well…I’m making ‘em anyway! I’ll just be nice and share…maybe.

  37. Hi! could you sign thequantities also in gramms? or could you suggest me a web site where i can find the conversion table?

  38. Made these today and they were freekin’ delicious! Next time I will use double stuffed Oreo’s b/c the best bites had the Oreo filling and they were sooooo good. Everyone LOVED them!!!

  39. Do you think these would taste good with a layer similar to 7-layer cookie bars (aka magic cookie bars) at the bottom? I’m wondering if the butterscotch chip flavor would work with or against the oreo… Any thoughts? (Ps… these look amazing!)

    1. omg I’ve never heard of magic cookie bars!? what have I been missing! I bet it would be good thou :)

      1. Magic Bars have been a Christmas cookie staple since I was a little girl! And oh so easy!

        In a 9×13 baking dish melt 1 stick of margarine
        Add 1 cup graham cracker crumbs, blend and spread evenly in pan
        Continue layering:
        1 can sweetened condensed milk
        12 ounces chocolate chips
        1 c shredded coconut
        1 cup chopped nuts (pecans or walnuts or nut of your choice)

        Lightly press layers together and bake at 350 for 15-20 min. Allow to mostly cool before removing from pan.

  40. I love this recipe – the cookie and brownie recipes are spot on. I’m wondering about variations now. I saw Golden Oreos at the grocery store, so I was wondering about a sugar cookie bottom, golden oreo, and what would go on top? Brownie? Blondie? I have no idea, so I’ll listen to whatever everyone has to say!

  41. These look awesome! My only concern is the cookie dough. My mom has drilled into me not to eat raw cookie dough (though I’ve snuck it a few times) because of the eggs. I know these go into the oven, but is it enough to be considered “safe”?

  42. I looooooooooooooooooooooooooooove these so much! Found them on The Londoner right around the holidays and immediately baked them for EVERYONE for Christmas and Hanukkah gifts! They became SO popular I started an Etsy shop and began selling them! By FAR my most popular item! Sooooo decadent!

  43. omg just reading this recipe.. seeing the pictures, made my mouth water and gave me the giggles. im literally shaking with excitement, i need to make these RIGHT NOW.
    this is the meaning of life. <3 mmmmmmm!

  44. These are amazing! I, too, looked them up after hearing Jessica Simpson mention them. BUT, what I love the most is the amazing brownie recipe. I have tried for years to make gooey brownies from scratch and have never really gotten close. I will NEVER buy a brownie box mix again! Thank you!

  45. These look incredible, but could you possibly put the amounts of ingredients in ounces/grams for us non-Americans out here?

  46. One of the girls at work made these, they are so sinfully good I can’t be left alone in the house with them.

  47. My family loved the brownies. I think next time I will make them without the Oreos. I’m sure they will be just as awesome.

  48. I saw these brownies on the Londoner and really wanted to make them. I decided to search around the web and see if anyone had made them from scratch. I found your recipe and made these yesterday. They are incredible!!! I’m an avid baker and not easily impressed by desserts, but your recipe for these are simple superb!

    Thanks again!

  49. These look amazing! My family is gluten and dairy free. Do you have suggestions on how I could make these for my family? Not all recipes can be made gfdf, so thought I would ask you before I try it!

    1. Hi Kristi! I’d use your favorite GF brownie and cookie dough recipes and then gf oreos if they are available? Hope that helps :)

    2. Oreos aren’t gluten free, but there are a couple of other good brands out there. Glutino is pretty good, but while dairy isn’t an ingredient, it says that it may contain traces of milk…

      1. Do you think this recipe could work in a 13×9 pan? Would you recommend using all of the cookie dough if you did that? And would that make the brownie layer too thin? I’m asking because both recipes seem like normal amounts for full recipes you would make if you were baking them alone. The pictures of your brownies look like they are pretty normal in height (and pretty insanely gooey and delicious!), but another blogger had pictures of this recipe in the 9×9 pan and they looked very tall! What would you recommend?

        1. Hi Michelle! I use a 9×9 pan because I want the inside of the slutty brownies to be a bit gooey! You could totally use a 9×13 pan and just keep an eye on the baking time and I’m sure it would still be excellent :)

  50. They are great. I haven’t made them in a while. I think I know what I’m baking today. Thanks for reminding me how great brownies are.

  51. Hi Gaby! This recipe is fabulous! I made them this morning with my sister. I did add one variation to the recipe: instead of chocolate chips in the cookie layer, we used mint-chocolate chips. Not really out of a creative moment- we just did not have normal chocolate chips. The mint chips add a really nice twist to these great brownies!

    Next week we are going to make Knock-You-Naked Brownies- can’t wait!

  52. hi there! I love how you beautifully display your recipes with lovely photos! you truly show the joy of baking from within. however, i’ve got a question. I tried the slutty brownies today and i realised that the top part of my brownies were burnt, but the bottom part was gooey and sinfully good. I use a convection microwave over and its maximum heat is 250 degree celcius. anyway, love the recipe none the less!

    1. Hi Chloe, thanks for your sweet comment!! I’m not quite sure about the convection microwave oven but did you bake it at 177 degrees C? I think that’s the conversion. let me know! thanks :)

      1. Hi Gaby! i baked it at 250 degrees celcius. My bad for forgetting to convert fahrenheit to celcius. ill try it at 177 degrees and let you know! Thanks! :) You’re such an angel!

  53. Hi Gaby!
    I loved the recipe, but i couldn´t get it right! The brownie layer ended up at the bottom of it.
    Did i do something wrong?!

    Love your blog and I´ll keep looking for your recipes.


    1. Hi Javiera! That is so odd that the brownie layer ended up on the bottom. Can you walk me through your process and maybe I can figure out what happened?


  54. Gaby,

    I had a similar issue where some of the cookie dough rose through the brownie mixture to the top but nobody had an issue with that. I’m a new blogger and I blogged about your brownies. I hope this is okay.


  55. Hey Gaby, I love your blog and I love this recipe BUT I wanted to let you know The Londoner did not create these brownies, she copied the recipe and claimed she created it :( The actual original recipe came from the wonderful Kevin and Amanda blog (check the dates and the recipe here ( Just thought you’d want to credit the real creator of these naughty treats as they truly deserve the credit. Sarah xo

    1. Hi Sarah, So glad you’ve also noticed that The Londoner blogger stole the recipe from Kevin and Amanda, she’s getting tonnes of opportunities from having stolen someone else’s idea its just not on, Gaby please credit the correct inventors!

  56. I need a Teacher’s gift for teacher appreciation , My daughters Teacher LOVES LOVES LOVES chocolate, so …..I was thinking maybe slutty brownies baked in a jar. Do you think this would work?

  57. I made these today after finding the recipe yesterday and longing for them! Have made 3 batches; I chose to make the cookie base chocolate as well( Just to be sure they would have enough flavour!)
    Two batches are heading out the door with my teens…. never to be seen again (the brownies that is)

    They are expensive and rich and I would not begin to calculate the calorie content( as far to alarming no doubt)

    Have a feeling I will be baking them again and again…..

    PS One of our dogs is called Oreo but he’ll not be getting his paws on them.

  58. As a brownieholic, any brownie recipe I find becomes fair game and this DEFINITELY falls within the meaning of “fair”. It is bookmarked, pinned and shared! Will I make them? You betcha!

  59. Hey Gaby…love your blog! I made these yesterday and the cookie layer was way over cooked, tasted burnt. Any suggestions? The brownie was fudgy as it should be- not overcooked.

  60. Loved these and so did everyone at work. Though next time I’ll halve the salt in both the dough and brownie mixture.

  61. I made these today for a surprise thank you party this evening. Can’t wait to taste them!!

  62. Oh Gaby! These were so good. I followed your recipe closely and they were the best cookie/brownie/thing I have ever tried. I loved them, my family and friends loved them too. Only problem – I keep being asked to make more! ;-)

  63. hi!

    may i know how many grams is 1 cup of butter? i tried making this afternoon (with 226g butter which i convert online) and it was all good except for the cooking dough which was too soft & oily, it didnt really set well. i bake for as long as 50mins+15mins more but it’s still the same.

    i used a 10×10 pan & i actually use up all e dough instead of half, is that the problem? or 226g butter is too much?

    pls advise! thank you.
    btw the brownies is still delicious! :D

    1. Hi Stefani – thats the right conversion for the butter so 226 is good to go! Did you melt the butter? That could have make it a little oily. And if you use all the cookie dough, that will definitely affect the baking time. Do you have a smaller 9x9x9 pan? It really makes a difference in baking times depending on the pan size. Hope this helps!

  64. Hi Gaby,

    I’m in a time crunch — could I use a tube of cookie dough and a box of brownie mix? Can’t wait to try. Thanks!

  65. I made these recently and they came out really yummy. I did make a few revisions though. I used a combination of white and light brown sugar with the brownies and added melted chocolate in there as well. (Just because I wanted a really moist, fudgy brownie. Plus I really wanted a deeper chocolate flavor) I also added grated chocolate to the cookie dough (Yup, chocolate makes everything better) and walnuts! These were so sinfully delicious! Even before they were baked I can already tell they’d turn out really well. Thanks so much!! Everyone loved them! Next time, I’m gonna try a cream cheese filling instead of Oreos! ;)

    1. Wow! Maia, I love the way you think! Chocolate makes everything better and there is no such thing as enough…am going to try it your way…as soon as the temperature drops below 70 degrees or so…(or you send me some out of pity…LOL).

  66. Okay I cannot stop laughing at the name. I mean I fell on the floor and rolled around holding my side from all the laughing. They look wicked good, which seems appropriate given the name.

  67. Why the foil lining the pan? Why not just butter the heck out of it before pressing in the cookie dough? I’ve been wondering that. I plan to bake these very soon! ;-)

  68. I currently have a pan of these bad boys in the oven (can’t wait!) and am I curious about the other half of the cookie dough… how long do I need to bake the cookies?

      1. Gaby,
        I took the brownies (and cookies) to a BBQ and I’ve never seen a pan disappear so quickly. I will definitely be making these again. Thanks!

  69. OMG im in the military and the only problem i see with the brownies is….. How the heck am i gonna fit into my uniform!… They look addictive i cant wait to try them and if it get fat ….. your coming to work out with me righ? ..HAHA

  70. OMG. I am speachless. Good thing this is online, because I’m not fingerless, just speachless.
    I’m also drooling, just a little.
    I cannot wait to try these. They may just be perfection.
    Thanks for the recipe for the brownie’s, I’ve had bad luck with homemade brownies.

  71. Tomorrow I am doing a make a wish foundation wish for a girl who has spent the last 6 years in hospitals. Her wish was to have her birthday party at the club I cook at. The cake she asked for was brownies. Me being the way I am wanted to do something less traditional. So to my satisfaction saw this recipe and decided that it would be perfect. I hope I was right. The chocolate I am using is a godiva chocolate. Wish me luck.

  72. If I need these for Saturday morning but can’t make them Friday night, will they keep well if I make them on Thursday?


  73. Oh, yes! These are the sluttiest brownies ever. Better than Better Than Sex cake even! My daughter introduced them to me and I bout lost my mind! As I am diabetic I immediately took a hit of quick acting insulin and another brownie! OMG! Our local store had BOGO free Oreos that week and I got 12 packages! For future use of course! Please try the Mint Oreos for a wonderfully different taste! I ate mine with Mint Chocolate Chip ice cream! Decadent!

  74. Dear Gaby. You are my hero. My friends and I LOVED these. We ate almost an entire tray. Thank you so much.

  75. Hi Gaby, I made this brownies but I had a small problems, as some people already mention it here.
    Everything was perfect and following your instructions until I place mold on the oven, 3 layers all in place.
    Once I finished cooking it, I saw that something was wrong, I was able to see parts of the cookie dough on the surface. Even more, when I cut it I saw that also part of the brownie layer ended up at the botom and that the oreo cokies were eveywhere.
    The only thing that I did different from the recipe was that I used a Silicone mold instead of a cooking pan.
    Could it be that because of the silicone mold I got that result?
    Thanks and by the way, despite it was a mess, they were delicious!

    1. Hi!

      I don’t think the mold has anything to do with it… but as far as the cookie dough and brownie layers, occasionally the cookie dough around the edges will creep up to the top and peak out a bit – but I’ve never seen the brownie layer sink to the bottom. Where the parts of the cookie dough you saw on top near the edges of your mold? Let me know and I’ll help get to the bottom of this :)

        1. when I make these the last 5min I put marshmallows and Carmel, then when I take them out of the oven I put chocolate chips. Yummmmmy

  76. gaby, pleae tell me if i can put the nestles cookie dough thern a layer of oreos and a box of betty crocker triple fudge br4ownie mix and bake it in the oven for the time the brownies are cooked maybe 40 minutes. thanks so much.

  77. It should be criminal to google “brownie recipe” and have this come up as the 8th entry. I chose brownies for dessert tonight because I knew I had all the ingredients on hand until I came across this recipe. A quick run to the store for oreos, ice cream, and chocolate chips and I am whipping up these. I am currently taste testing the brownie and its still a bit too warm. I am thinking this brownie is probably best served at room temp or even cold. Still yummy though…thanks for sharing! Next time I might try this with nutter butters!

  78. Question – How doughy should the bottom layer be? When I made these the cookie dough layer seemed undercooked, but the brownie layer was done. I was using a glass pan. Also, I have read comments about half the cookie dough? The recipe does not say anything about using half the cookie dough.

    1. Hi Alexa – what kind of baking dish did you use? glass? Did the brownie recipe cook? Let me know and I’ll walk ya through it as best as I can!

  79. I just taste tested them! Ooooh they are so delicious!!! I need to hide them from my family or they’ll be gone by tomorrow, thanks for the recipe :)

  80. I am baking this at this very moment and the cookie dough has burst from under the brownie mix and is spilling over the sides! WHY!

      1. This happened to me, too! Minus the spilling over the sides. I used a 9x9x9 pan. My best educated guess is we added too much of a leavening agent like the flour or baking powder. Maybe we measured those ingredients wrong? Either way, it still turned out delicious! It just looked a little funky lol

  81. I made these last week for a party I went to because I wanted to test them out on a big group of people and get some feedback. I’ll admit that although I have a major sweet-tooth, I was a little scared they’d be too rich. I was pleasantly surprised. First off, they’re easy and fun to make; making all the batter from the recipe took under an hour, and they didn’t take too long to bake. Secondly, they taste AMAZING. They’re not overpowering at all, instead they’re the best dessert bar I’ve ever had (and I’ve had quite a few, lol). They were a huge hit at the party; everyone who tried one came back for more and the pan was empty long before the party was over. Thanks so much for sharing this awesome recipe, I’ll definitely make these again and again (and again). :)

  82. Just pulled my first batch outta the oven n completly in love with the smell all over the house!! Brownies look good but cookie dough looks undercooked a bit… Im assuming its meant to be undercooked? Either way a tub of vanilla ice cream n hot fudge are calling out for my baking flop lol… Maybe i flip the layers next time

  84. Hi, I was wondering if this can be made in a cupcake pan with the same layers just one oreo per cup? Would the temperature still be the same for the cooking or should I increase or decrease it? How should I adjust cook times?

    1. I’ve never tried doing it in individual dishes – but I’m sure it would work! I would just watch the baking time as it will take far less time with smaller baking containers. :)

  85. Hej Gabi, what is AP flour. It is a normal flour? I have to try this recipe because my boyfriend is a chocoholic. And 350 degrees is not to much, her in Europe is the max in a oven. Are you using american degrees.? Thanks Carmen

    1. I’ve made these with store bought brownie mix and sugar cookie dough to save time and they turned out really good, pretty much the same if I’d made them from scratch.

      1. hey Tracy!! Yup, they will be totally delish with store bought dough too!! Either way – I’m obsessed with them! Glad you liked them!!

  86. Those look absolutely delicious! One of my favourite kind of brownies are the double fudge ones my Mom makes whenever I come home from overseas travel. These are definitely slutty in a good sense :)

  87. i love making this recipe! And this we are in the month of October and Halloween is right around the corner. i decided to use Halloween oreos! tastes the same and adds a little more color to this amazing slutty brownies!

  88. I tried this recipe with a glass pan and the dough layer turned out uncooked and sloppy :( the brownie was amazing though. I may have messed up the conversions to grams though.

    Would a tin be better?

    1. Hi,

      I dont think the tin vs. glass pans would make a huge difference – although I do use tin plans in my kitchen. I would double check on the conversions since I’ve made these a ton of times and have never had them uncooked. I’ll see if I can do the metric conversions and add them to the post :)

  89. I’ve had mine in the oven for an extra 15 minutes now – and the insides still aren’t done. they are runny and gooey inside. I made regular cookie dough, and used a boxed brownie mix for the sake of time. I am using a 9×9 metal pan, lined with foil and sprayed with Pam. Any thoughts why they won’t cook?

    1. Hey! I’m not sure why they aren’t cooking. How long does the brownie batter mix say to bake for? My brownie recipe cooks a bit faster than the box ones do, so perhaps that’s part of it?

  90. These look amazing!! I’m thinking of making these for next weekend when I visit my best friend for a Halloween party weekend. Perfect for us and her roomies!
    Why Tin foil, did you find parament paper stuck to the cookie dough?

    1. Hey Taylor, I’d keep an eye on it… since yours will be a little less thick but wider, it might still take the same time… but you just want to look for the brownies to be slightly gooey in the center and then take it out and let it cool completely and stop cooking :)

  91. What degrees do you use? Farenheit or celcius?
    If Farenheit, how many degrees shoud I have in celcius?
    Hug, Moa :)

  92. Good stuff, but the brownies were undercooked and gooey. I used a 9×9 pan (metal) and cooked for almost 45 minutes because my knife wouldn’t come out clean. Finally took them out because I didn’t want the cookie layer to burn. (It was perfect.) I let these cool completely, but they completely fell apart due to the gooey brownie layer. More than half were thrown away because I wouldn’t serve something so sloppy and undercooked to anyone.


    1. hmmmm that’s interesting. How long did you let them cool? Sometimes it takes a while for the brownie and cookie layer to set up. Let me know and we’ll get to the bottom of it!

  93. These are ridiculous in a good way. They are also about the richest thing in the world. I can only eat about half the pan. They need a new name, how about Chiporeonies?

  94. I am attempting to make these brownies with a box brownie mix. Because your recipe uses a 9×9 pan, should I cut the box brownie mix in half or can I use a 9×13 pan anyway and make the cookie dough part thinner?? Should I double the cookie portion of this recipe for a 9×13 pan?

    1. you should use the 9×13 pan and just have a slightly thinner layer of cookies and use the full amount of box brownies!! Happy Baking :)

  95. im so excited to bake these for my friends birthday..i am just going to use store brownie mix and store cookie dough. will the cookies be burnt for cooking it for 45 mins?

  96. I thought you could crush the oreos.. I made a batch with the oreos crushed the tasted ok but didnt have the layered look..

    1. Hi Shannon,

      I’ve never tried it with crushed oreos – I bet it tastes the same – but ya you won’t get that layered look. I’m going to try it thou! I bet it could be fun :) Or another brownie recipe with crushed oreos!!

  97. I started making these and my brownie mix is a little lumpy and not as smooth and glossy as it usually is. Is it supposed to be that way?

  98. Today is my birthday and I made these for myself for the first time and oh goodness they came out so perfect. I added swirls of whipped cream to each brownie when serving. Not only were they beautiful they were heavenly to eat :D

  99. I made these both ways, from scratch and with the boxed mixes. SOOOOOO Good either way. I went a little crazy with my 4th batch for a cookie party: added Rolos, and marshmallows to the Oreo layer then topped with the brownie mix. They were super decadent and a big hit with the other partygoers.

  101. Hey do you think it would be ok if i made the batters in the morning and then combined and cooked them at night?

  102. My best friend’s mom and I have both made these and we have both had the same huge issue…the oreos take all the moisture from the brownies and cookie dough and you’re left with this hard dessert that the brownie completely falls apart on…not sure how to fix this or how everyone else is gettin such epic results but does anyone have any ideas on how to make the oreos not dry everything else out so much?

    1. Hey Amanda! Are you using the homemade cookie and brownie recipe? I just did a step by step recipe for this on the peppermint slutty brownie post – you can take a look and see if I addressed your question there.

      Let me know! Feel free to email me directly and I’ll help out at much as possible!!!

    1. Hey Taylor! I always use unsalted butter – but to be honest, if you only have salted butter just go ahead and use that and omit the extra salt from the recipes :)

  103. I wanted to know if I could use a brownie bites pan. If so, at which temperature should I bake them and for how long?

    1. You can totally use a brownie bite pan! Same temperature for sure – but I’ve never done it in that kind of pan so I don’t know about the length of time. I’d just start with about 15 minutes and keep my eyes on it :)

    1. Hi Isabelle! How long did you bake it for – and did you use a different size pan? I’d love your feedback :) Thanks!

  104. Hi Gaby,
    I tried to make these for a party using cookie and brownie mix just as a time saver and the brownie layer just would not cook. I used a square glass pan. I kept putting them back in the oven for at least another 20-30 minutes in intervals of 5-10 minutes and yet the middle of the brownie layer was still runny and undercooked. Do you have any idea why this happened? I can’t seem to figure it out!

    1. Hey Taylor! I’ve used box brownie mix too when I’m in a pinch for time. And I mut say, the glass pan will make a bit of a difference in baking time but it shouldn’t be 30 minutes worth. Do you have another pan you can try – or a bigger glass pan, and then the brownies would be a bit thinner? Let me know! I’m happy to work through it with you until they are perfect!!

  105. I added carmel pieces ntop of the oreos and used a Marie Calender brownie mix and Nestle toll house resipe for Chocolate chip cookes. Totally delish and called for milk and lots of it!

  106. I made these for dessert this weekend – big hit! This is a keeper! Of course with a bunch of kids – and their friends over – we’ll have to change the name of these brownies! LOL!

  107. These are AMAZING! It is so worth using these recipes instead of the store bought. I would recommend refrigerating them over night before cutting into them. That way they hold together and still taste fudgy delicious.

  108. Hi Gaby….I made these tonight. They are awesome! I didn’t have alot of Oreos, but they were still great!!!! Check them out on Instagram…. @dulceminamd…

  109. These didn’t turn out right at all! Which is terrible, because they’re absolutely great in theory. I had to leave it in the oven for about an hour before the brownie layer was done. It was quite a mess, really. I’m wondering what I did wrong, because everyone seems to be raving about these.

    P.S. I followed the recipe to the T.

      1. I used a 9×9 pan :(
        But I’m going to keep trying these until I get them right, because look how beautiful!

        1. 9×9 is the perfect size!

          Next time you give them a go – take them out of the oven at the given time, and let them cool. The brownies continue to bake a bit once they are out of the oven due to the residual heat… and then refrigerate them once they have cooled to room temp to firm everything up! Keep me posted for sure :)

    1. you just need to melt the butter – so if you melt it in the microwave, you can mix it all normally if you want!

  110. Step #8 is a bit confusing… How do you press down cookie dough to the tin foil when its liquidy? Won’t the oreos sink through as well as the brownie mix? Thanks :)

  111. Is it okay to use Ghirardelli brownie mix and my own cookie dough recipe as long as it’s not liquidy?

      1. To make these brownies even sluttier, how about a bit of a glaze? I have a plan to make these to share with my co-workers (am retiring soon), and am thinking that a glaze would make them dead slutty!

    1. hey sage! you can totally buy them if that’s easier for you. I prefer my homemade mixes – but I’ve done it both ways and it works for sure!

  112. my 9×9 pan is currently on loan to a friend, will these be fine to make in a 9×13? How would you suggest altering it so it would work? Thanks!

    1. Hi Sheri! A 9×13 will still totally work. You’ll just need to keep your eyes on the brownies since they will be a bit thinner, and that will affect the baking time. Just be sure to check it every once in a while after 30 minutes to see when the center is not jiggly and almost cooked!

  113. will it make a difference if I used nestle cookie dough and brownie mix? instead of doing it from scratch?

    1. hey chelsea! yes it will make a difference because the brownie mix makes a large quantity than why my homemade recipe calls for. You can still totally do it – but you might want to use a 9×13 pan since the brownie mixture makes a lot. And it will take a little longer to bake – so you’ll have to keep checking

  114. Well I made last night -I used a box mix for bownies cuz I was pressed for time -came out raw, everytime I chacked the brownie, -not alittle raw alot, so I had to keep adding more time by the time brownies are done the cookie dough was super hard -I gotta cut off or should I say saw off bottom layer to eat the brownie -I m gonna try this recipe again but in a 13×9 not the 9x 9 pan that’s recommend -way to thick.

    1. hey gigi – the homemade brownie recipe for these makes a smaller quantity than if you use a box mix – so that will absolutely affect the baking time. If you use a box mix – you would be better off in a 9×13 pan because the brownies will be so thick which will take longer to bake and will make the cookie layer crispy and overbaked

  115. Hi Gaby and thanks a lot for your wonderful recipe! My grandmother as well as my mother and her boyfriend have gladly overindulged into these goodies. They’re almost gone and I only created them last night! (without the oreos :( ! )
    I just wanted to leave something that I found useful while making them. Because I used your cookie recipe, the dough was the perfect consistency but was not packable into the container at room temperature so I put the container along with the cookie dough into the freezer and then I was able to pat it down into a nice even layer!
    Thanks a lot, and I’ll be back for more of youre nice recipes!

  116. Hi, I would like to know what brand you get of the ingredients needed. And where you buy them. That would be great (: I’d Love to try your homemade recipes for the cookie and brownie layer. Thank you (:

    1. Hi Cray, I don’t use anything special – just the generic versions of flour, sugar, kerry gold butter, ghiradelli chocolate chips! Hope this helps :)

  117. Hi Gaby! Can you recommend a substitute for the eggs? I’m not too keen on using applesauce because I did once and it made my cake very (for want of a better word) squishy -.- I was thinking maybe baking soda+some water. Any ideas? This looks incredible and I can’t wait to try it! Thanks :)

    1. Hi Bhavna,

      Unfortunately I’ve never done any experimenting with egg substitutes so I can’t recommend something that I 100% know will work. Sorry I can’t be of more help.

  118. I made these last year for my sister-in-law’s homecoming. Everyone raved at how sinfully delicious they were. I still receive constant requests for more. Yummy.

  119. Made these last weekend for my hubby’s birthday. I didn’t have any Oreos so I used peanut butter cups. I also don’t have a 9×9 pan so I used my 8×8. They fit but they were a little thick. The end result was delicious though. I”ll definitely be making these again.

  120. Fell in love with these. 3 layers of my favorite. My best friend and I are making these tomorrow!! *excited*

  121. I was watching Don’t Be Tardy with Kim Zolciak (from Real Housewives of Atlanta) and on the most recent episode, they were making Slutty Brownies! I was totally wondering if they were using your recipe and thought of you! I hope they were! :)

  122. I’ve made these before, and I want to make a 13×9 pan. What would the conversions for that size pan be?

  123. I have yet to make these… I plan to do so in approximately 2 hours. :) I’m extremely curious, for all of you with youngsters at home, do you keep the name of the brownie when telling them what they are? Do you tell your kids “Hey, would you like a slutty brownie?” or do you knock it down to a PG rating and just call them “cookie brownies” or some variation. The human interactions of this particularly sinful treat intrigues me. :)

  124. Hi Gaby!
    I found this on Pinterest and I want to make them today! They look sooooo good! I just have one question: to save time I’ll be using boxed brownie and cookie dough mixes, but how do I know how long to cook them for? Is it different when using a box mix? Or do I just look at how long the brownies take to cook and go by that?

    1. Hi Christina! The recipe baking time will be similar, but just keep an eye on them while they are in the oven so you don’t over bake them! I’d say they will take a bit longer as there is more brownie batter in a box mix that the recipe I have :)

      Let me know how you like them!

  125. Hi, I have one more question: can we use a glass pan if we don’t have a 9×9 brownie pan, or should we just go with an 8×8 brownie pan?

    1. I’d go with the 8×8 brownie pan – just because the glass pans tend to bake a little differently!

  126. Hi there,

    These look amazing! Cannot wait to make them. I don’t have a 9×9 pan. Can I use a 9×13 pan if I line it with extra cookie dough and use more oreos. Would I need to double the brownie recipe, too?


    1. You can use a bigger pan for sure – just be sure to bake them for a few minutes longer as it will take longer for the center to cook since it’s in a larger pan :)

      And yes, I’d double the brownie recipe!! Or you could make it times 1.5 and that would probably be perfect

  127. I’m going to make these tonight. But here’s the twist… I’m going to use peanut butter cookie dough instead! Peanut butter and chocolate were made for each other!

  128. Just thought I’d drop a little hint here that might help some of you who are like me with a decision you might consider having to make when making this.

    When you’re layering the brownies and you notice those little gaps between the Oreos, you might wonder what could go there. For that matter you might have wondered how delicious the brownies might be with Reese’s Cups instead of Oreos.

    Well… you don’t actually have to make a choice. Reese’s Miniature Cups fit perfectly in those gaps between the Oreos. Be warned though… you’ll want to have a cup of water handy to drink after eating such a creation. Especially if you like a side of Oreo ice cream with these ;)

  129. Pingback: Labor Day BBQ
  130. Thanks for the reminder! I made these a couple of months ago and they were awesome, even if I got the oven temperature conversion wrong. I’m waiting for the weather to cool before trying them again, although I want to make the slutty blondie brownies. I haven’t seen golden Oreos in the UK, so I’m going to go with a British favourite, custard creams. I’ll let you know how I get on. I might also try another British favourite, Bourbon creams, instead of the Oreos.

  131. These are marvelous— super moist, deep chocolate flavor, and eye-catching. My only problem was serious overflow when using a 9×9″ dish. Good thing I put a cookie sheet under the baking dish. I plan to bake another batch this weekend, and I’ll use a larger baking pan this time. Are these brownies worth the effort? You bet, and when you fill your belly, you can just rub the rest directly on your thighs!

  132. These are so, so good. But just an FYI, they were NOT created by The Londoner. Bloggers Kevin & Amanda posted their recipe almost a full month before Rose posted her boxed mix version.

  133. I made these the other day and brought them to work everyone loved them, they came out good although i baked them in a 9X11 silicone pan instead of a 9×9 pan. I had no issues with them at all… will definatly use this recipe again

  134. Can these be made into individual portions by putting them into cupcake liners? If so, would the brownie pour down next to the oreo and create a brownie with a surprise inside?

    1. yes! that would totally work. Just watch the baking time as it will most likely be a bit shorter than a pan of them :) Also, I love that idea!

  135. Hi!
    I’m from Denmark – and that recipe – I LOVE IT!
    I am making the brownie today, but you write ‘cup’ a lot ind the start by how much you need for this brownie – I just need to know, witch size the cup is, or if theres any other way ..

    Sarah :)

  136. They do look amazing, and I will try them….. However, they don’t look slutty enough for me! (what does that say about me?). To me, slutty needs a layer of dripping, oozing something… either like a chocolate ganache, or a caramel/toffee type of layer. Do you smell what I am stepping in?!

  138. These are always my go to dessert now. To date, I have had 4 people ask me to marry them after taking the first bite.

  139. Can these be done with a 9×13 pan instead of a 9×9? I’m baking at a friends house, and I don’t believe they have a 9×9 available!

  140. I cheated when I made these, I used a boxed brownie mix and already made cookie dough. Came out great.

  141. Hi Gaby! I know this is an old post, but I had a question about the brownie layer of this recipe. I have tried to make this recipe before several times, and the brownies always come out undercooked. Always. I’ve cooked them over double the time stated on the recipe, and the brownies are still so gooey that the entire thing falls apart when I cut it, even after I’ve let it set. I used a 9×9 pan with a full boxed brownie mix – do you think that could be the problem?

    1. Hey Amanda!!

      The issue is in the brownie mix. The box mix makes a large quantity than what my recipe on here yields. If you want to cut the box mix in half, it should then work perfectly!! :) And continue to let it set, as that really helps!

      Keep me posted!

  142. They look Slutty and SEXY AT THE SAME TIME…..will be sharing this with the teachers I work with. Thanks and your very talented. love your stuff!

  143. Oh My God these brownies smell so good
    Mine r tasking longer to bake as we’ll
    Glad to know I’m not the only one
    Can’t wait to try

  144. I’ve made these for some time using box or pkg mixes. Cooking time is affected with that brownie mix and I have to watch so they don’t get hard. I drizzle sweetened condensed milk over the Oreos before topping wirh brownie mix for a caramel taste. We are a family of chocoholics so it’s a staple!!

  145. Hello! I found this recipe of yours and I want to recreate it! I have one question though, how did you cut the brownies to perfectly? Everytime I make brownies they always crumbles down. :(

  146. Made this brownies last night, and they were delicious. Thank you for all these delicious recipes.

  147. Gaby, I made these for my husband’s bday last week and we froze half of them so that we wouldn’t eat them all. I caught him eating them from the freezer this weekend…when you slice them frozen they have the consistency of fudge omg. Almost better than when they were just baked. Thanks for sharing!

  148. I’ve just got to ask this coz I’m a little worried… this is the first time I’m making this!
    Normally my brownies are always undercooked in the centre, so I leave them in the oven for about 10 more minutes (my family hates undercooked brownies).
    When I took the brownies out I stuck a knife in the centre and it came out with a bit of brown batter. I thought I’d better stick it back into the oven, so I did.
    This time, I realized that somehow I could see bubbling after the oven timer was done, and I took it out of the oven.
    Upon cutting, I realized the cookie layer was still super moist and looked a little like glutinous rice paste. I thought that the cookie layer would be firm and crunchy! Is this because I cut it too quickly after removing it from the oven (about an hour or so?) Does this mean the cookie layer was undercooked? The brownie layer’s been completely cooked and is a little crumbly (no undercooked brownie parts), so I’m a bit perplexed because I thought the cookie layer would cook that much faster than the brownie layer.
    Was there something I did wrong, perhaps? Hope you could help shed some light on the matter! (:

    1. Hi Hazel! Hmmmm I always let the brownies set for about 4-5 hours after baking because they are so dense – and then I cut them. It’s easy for them to fall apart when you cut them while they are still warm. What kind of baking pan did you use? LMK and I can help get to the bottom of this :)

  149. I just made these for the 1st time and they are amazing. I made them in a 9×13 pan and the only change I made was to use the new Oreo Thins. I didn’t want to double the recipe and by using the thins there was just enough brownie batter to cover. Of course they are not as thick as the 9×9 but still delicious. Can’t wait to share them with my friends!
