Cookie dough Oreo brownies (aka “slutty brownies”) are layered with cookie dough, Oreos and brownie batter to create the ultimate dessert bar.
We’ve all got a sweet tooth, and we all know those times where we can’t help but give in to its sugary cravings. Whether it’s a delicious dessert, a mid-afternoon snack, or the late night craving, there’s that voice in your head saying “treat yoself.”
My go-to is usually straight up chocolate, but sometimes that voice is a little more indecisive, and pretty much anything sounds appealing. Maybe a chocolate chip cookie? Brownie? Oreos?!
Cue the little girl from the Old El Paso commercials: Por que no los dos? Or in this case, los tres?
Recently I was called upon by my younger brother to send his first college care package. It seems he’s missed being the official taste tester for my blog, and I think we can all agree that college gives you more than enough reasons to indulge your sweet tooth (study snacks, stress eating, midnight munchies… need I go on?).
So, I decided to send him the ultimate baked good: chocolate chip cookie dough Oreo brownies. Now there’s a mouthful (pun intended)!
What are slutty brownies?
“Slutty brownies” are dessert bars made up of layers of cookie dough, oreos and brownie batter. They are three favorite desserts molded into one. You can make them using storebought brownie mix and cookie dough, however making them from scratch is better.
How to make cookie dough oreo brownies
The cookie dough layer goes on the bottom because it is sturdier and bakes a little quicker. This makes it a good base to hold the Oreos and brownie layer.
The Oreos are layered on tops. Layer as much as you can fit (I got about 16 on there, but if you cut them in half you can fit more). Finally pour the brownie batter on top. The brownie batter will fill in the gaps between the Oreo cookies and create a nice shiny, crackly top.
These cookie dough Oreo brownies are very dense, so be sure to give them the full time in the oven in order to bake through all three layers!

- 1 1/4 tsp vanilla extract
- 1 cup plus 2 tablespoons unbleached all-purpose flour
- 1/2 tsp salt

Cookie Dough Layer
- In a bowl, whisk together the flour, salt and baking soda. Set aside.
- In the mixer fitted with a paddle attachment, cream together the butter and sugars until fluffy and light (I usually mix for 3 minutes).
- Beat in the egg and vanilla, making sure to scrape down the sides of the mixing bowl.
- Slowly mix in the flour mixture until combined.
- Stir the chocolate chips. Set bowl aside (stick it in the fridge if you like).
- In a double boiler or microwave, melt semisweet chocolate and butter, stirring often. (See tips for melting chocolate here). Once melted, whisk in cocoa and instant espresso and let cool.
- Meanwhile, fit your mixer with a whisk attachment. Whisk together eggs, sugar, vanilla, and salt, just until combined—about 30 seconds.
- Whisk in the warm chocolate mixture. Then, stir in the flour with a rubber spatula. Set aside.
- Layer the cookie dough on the bottom of the prepared 9x9 baking pan, pressing down to form the bottom of the brownies.
- Layer as many Oreos that will fit on top of the cookie dough. No need to overlap. (I think I managed 16).
- Slowly pour the brownie batter on top of the Oreo layer and make sure it evenly layers on top.
- Bake for 40 to 45 minutes. Test with a toothpick: if it comes out clean the center is done, if not, let the brownies cook 5 minutes more. Let the brownies cool before serving!
