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 F.
  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 for at least 2 hours 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,

  1. 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!!

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

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

  4. 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.

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

  6. 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!!!

  7. 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.

  8. 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!

  9. 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”?

  10. 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!

  11. 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!

  12. 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!

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

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

  15. 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.

  16. 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!

  17. 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 :)

  18. 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.

  19. 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!

  20. 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!
