It’s all about Slutty Brownies today! Layers of cookie dough, Oreo’s and homemade brownie batter = it’s perfection. Keep reading for all the tips and tricks 🙂

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 and they are basically it’s a SUPER POWERED brownie made with layers of cookie dough, oreo cookies, and then a rich and decadent brownie layer. They are EVERYTHING. Seeing as how I’m a private chef, I made them for every single person in my life, including Jessica Simpson who is my current private chef client, and when asked on Leno what made them slutty she replied.. it’s because a lot of things go into them. GENIUS.

They are decadent. One small bite will be enough to satisfy any sweet tooth but why stop there!

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 chocolate-y 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.

Make Slutty Brownies immediately.

They’ll 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.

VERY IMPORTANT SLUTTY BROWNIE FAQ’s:

  • This is the pan I bake these in – it’s a 9×9 square pan from Amazon and it’s the best. It’s a non-stick square pan – which is what you need. A glass pan or a pan of another size won’t yield the same results as the photos here.
  • Cool the brownies once they come out of the oven for at least 1 hour before slicing and serving if you want perfect square pieces.
  • You can use any kind of Oreos you want – double stuffed, regular, flavored, birthday cake, red velvet etc
  • IF you use a box mix for the brownie layer, you won’t want to use the entire batter as it yields more than my homemade brownie recipe. You just want to have enough brownie recipe to cover the oreos on the top layer.

Ingredients
  

For the Brownie layer:

  • 10 tablespoon unsalted butter
  • 1 1/4 cups white sugar
  • 3/4 cup cocoa powder
  • 1/2 teaspoon kosher salt
  • 2 teaspoons vanilla extract
  • 2 large eggs
  • 1/2 cup 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 teaspoons vanilla extract
  • 1 1/4 cups flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1 cup semi-sweet chocolate chips

Instructions
 

For the Brownie layer:

  • 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.

For the Cookie Dough layer:

  • Cream together the butter and sugars in a mixer. Add the egg 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.

Assembly:

  • Pre-heat the oven to 350 degrees F.
  • Line the bottom of a 9x9 baking pan with tin foil and then spray the tin foil with a layer of baking spray.
  • Layer the cookie dough on the bottom of a 9x9 baking pan, pressing down to form the bottom of the slutty brownies.
  • Layer as many oreos that will fit on top of the cookie dough. No need to overlap. One single layer will do.
  • Pour the brownie batter on top of the oreo layer and make sure it's evenly layers on top.
  • Bake for 30-40 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. Slice and serve.

      When cooling the slutty brownies is it best to cool in pan for two hours or lift it out of pans and cool for two hours? I worry the batter will crack.

  3. Leanne

    Hi Gaby.
    I just want to thank you for this lovely recipe! These came outstanding. You can definitely taste the homemade goodness in just one bite! Ghirardelli boxed brownie mix is the only thing that comes close to this!

  5. Tracy

    Hi, how should I change ingredients for Slutty Brownies to make this a 13 x 9 recipe and keep same thickness? Looks delicious! Can’t wait to try these for my husband’s birthday!

    Thanks!

    • Gaby

      Hey Tracy – won’t quite work the same in a 9×13 since that affects the baking time since it’s a larger area. I’d do 2 9×9 pans if you can!

    • Maria Ellsworth

      Should these be stored in the refrigerator or on the counter?

    • Gaby

      fridge if you’re going to take more than 48 hours to eat them!

  6. Dee

    Hello!
    Do you think I’d be able to make the batters the day before, assemble the brownies then cook them the next day? Or does everything have to be room temperature?
    Thank you!

    • Gaby

      you can prep ahead and let the batters come to room temp before assembling!!

    • Gaby

      you can prep the day before – just let the batters come to room temp a bit before assembling so it’s easy to spread the brownie layer

    • Caroline

      Looks like a great recipe. I only have an 8×8 pan. Is it ok to use an 8×8 pan instead of a 9×9 pan?

    • Gaby

      Yes – just might take a few extra minutes to bake since it will be thicker

  7. Savannah

    Hi Gaby,

    Great recipe! A few questions: I want to make this in 2 8×8 pans. So can I use one box of brownie mix or do you suggest two boxes? Also, if I want to use store bought cookie dough, do I buy one tube or two? Thank you in advance for your response 🙂

    • Gaby

      you’ll want to buy 2 of each – but you should only use 3/4 of each store bought package if that makes sense.

  8. Robbie

    These look amazing! If I make these on Wednesday and need them for a Saturday event, when should I take them out of the freeze on Saturday? Do I need to cover the pan with anything while in the freezer and should I wait to cut them until Saturday?

    • Gaby

      I would bake wednesday, let cool entirely. wrap is plastic and freeze. then take out and thaw 6-8 hours before serving and slice!

  9. Nikki

    For the cookie dough, do I just mix it in a bowl or am I supposed to put it over the stove in a saucepan?

    • Gaby

      cookie dough gets made in a bowl – the video is helpful with a step by step!

  10. Elizabeth

    When I did this the cookie layer wasn’t being baked. The brownie layer was fine and I put it in for an extra 10 minutes but the cookie layer was still super soft and I didn’t want to ruin the brownie layer. Now sure what I did wrong

  11. Ginger

    Made this with store bought cookie dough brought to room temp (1 tub or 3 packs of squares) and used wax paper instead of foil In a 9×13 pan – your brownie Recipe was perfect to spread on top, just added 5 mins at a time till done (toothpick clean). Thanks for posting, love these things and the fam does too!

  12. Maria Hicke

    What ice cream could you eat this with? I’m thinking vanilla? I’m excited to taste this! Also making this for my hubby’s birthday..

    • Mauricio A Brito

      They are good recipes thank you for sharing them. ☺

  13. Heather Littrell

    Mine was so delicious But when I cooked it at all ran together and it didn’t look pretty and separate like this. What did I do wrong? I did make it all from scratch.

    • Gaby

      did you alter any of the recipe and what size pan did you do it in?

  14. lori gagnon

    OMG AMAZING!!!!! Made the first time with store prepared mix and cookie dough. Made again according to recipe – no comparison!!

  15. Ann

    HI,

    OH MY GOODNESS!! This recipe was sooooo good. I made this during the covid-19 outbreak, but I made them so many times I think my family might be sick of them. Anyway, thank you so much for this recipe I love it and make it all the time.

  18. Mara Berube

    Hi! Can I make this as “cupcakes” Instead? Would it just be A little bit less cooking time?

    • Gaby

      yes you can and correct – baking time would need to be adjusted! I’d start at 20ish minutes and keep my eyes on them

  19. zoe

    what do i do if i use more than half of the brownie batter to make sure the cookie dough doesnt burn on the bottom?

    • Gaby

      brownie batter goes on the top layer! No need to use it on the bottom. Cookie dough won’t burn

    There is no flour at the store, can I use gluten free flour??

  21. Susie

    Really delish. We took it up a notch by adding a melted Caramel layer to seep into the nooks & crannies around the Double Stuffs…1/4 c Cream & 1 bag Kraft Caramels…microwave for 60 seconds…mix with a small whisk until it reaches its smooth swirly goodness & pour over Double Stuff Oreo layer, followed by Brownie mix. It’s Yumalicious!

    5 stars
    Absolutely delicious!! It was fun and easy to make, and I loved making it all from scratch! My husband also loved it and he’s usually pretty picky. The brownies were rich, but not so rich that you could only have one. Love it!

    • Gaby

      so you can easily lift them out once they are baked

  23. Lisa

    I made this the other day . Delicious. I have a question. Can I make the recipe for the cookie dough from the toll recipe chocolate chip cookies?

    • Gaby

      it ends up being a different ratio of cookie dough to brownie batter / oreos. So bottom line is yes you can – but it will affect the baking time

  24. valerie Bartlett

    I have made these with reese peanutbutter cups, Andes mints, Heath bars, mounds in place of the oreos, All of the variations were awesome. Only thing stopping the variation is your imagination.

    • Bryn Adams

      When making it with peanut butter cups, was everything else the same in terms of baking time, etc.? And just layering them like you would with the oreos?

  25. Nicole

    I love this recipe, and I’ve made it multiple times! If I just want to make the brownies, should I double the recipe and then do the same time and temperature?

  26. Janine

    5 stars
    Hi can the cookie dough and brownie batter be prepared beforehand and frozen and then baked at a later date?

    • Gaby

      yes – just bring to room temp before trying to assemble

  27. Simran

    Hey! The recipe looks so good I feel like trying them right away.
    But is there any substitue for eggs? Since i want to make a vegetarian one.

    • Gaby

      Haven’t tested it with an egg substitute so can’t say for sure

  28. Jan

    What brownie mix would you use and could you use premise cookie dough and how much? I need shortcuts please. I’m sure others do also. Thanks

  29. Charlotte

    I am the resident cook at our office and these have become a favorite. We have a group of guys who go absolutely gaga over peanut butter so I now make a batch with Oreos and another with mini reeses
