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 :)

  2. 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. :)

  3. 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!!

  4. 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 :)

  5. 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!

  6. 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 :)

  7. 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?

  8. 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 :)

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

  10. 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!

  11. 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?

  12. 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 :)

  13. 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?

  14. 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!!

  15. 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?

  16. 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 😀

  17. 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.

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

  20. 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 :)

  21. 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!

  22. 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!!

  23. 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!

  24. 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!

  25. 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.

  26. 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…

  27. 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!

  28. 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 :)

  29. 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!

  30. 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!

  31. 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

  32. 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

  33. 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!

  34. 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 :)

  35. 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.

  36. 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.

  37. 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.

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

  39. 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! :)

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