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 yo self.”

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?!

Why this recipe works: Well, it’s homemade. No boxed mixes, no store-bought cookie dough. It uses my chocolate chip cookie recipe and fudgy brownie recipe. Then there’s an Oreo cookie sandwiched in the center so what’s not to love?

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 store-bought brownie mix and cookie dough, however making them from scratch is better.

Step by step instructions

This recipe requires a couple steps, but it boils down to this: make both the brownie batter and cookie dough from scratch. Then all you have to do is layer.

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. It is my chocolate chip cookie recipe cut in half.

You need butter, sugar, brown sugar, egg, vanilla, flour, baking soda, salt and chocolate chips. Mix the ingredients according to the instructions and spread the dough on a parchment-lined square baking pan.

The Oreos are layered on top of the chocolate chip cookie dough base. Layer as much as you can fit. I got about 16 on there, but if you cut them in half more Oreos fit in the pan. You can also use double stuffed oreos if you like extra filling.

Brownie layer

Finally pour the brownie batter on top. I cut my fudgy brownie recipe in half to make the brownie batter. You need chocolate chips, butter, cocoa powder, eggs, sugar, vanilla and flour. Mix the ingredients according to the instructions. The brownie batter will fill in the gaps between the Oreo cookies and create a nice shiny, crackly top.

Frequently Asked Questions

How long to bake slutty brownies:

These cookie dough Oreo brownies are very dense, so give them the full 35 to 40 minutes in the oven in order to bake through all three layers! Insert a toothpick in the center (try to avoid an Oreo). The toothpick will come out with little to no crumbs.

Can I use double stuff Oreos?

Yes! I’ve used double stuff Oreos before and they worked perfectly. You can also use flavored Oreos if you’re feeling adventurous!

Storing cookie dough oreo brownies:

Store slutty brownies in an airtight container at room temperature for up to 5 days.

Freezing cookie dough oreo brownies:

Once the brownies have cooled, use the ends of the parchment paper to lift the bars out of the pan. Leave the bars uncut and wrap the entire bar in plastic wrap then aluminum foil. Freeze for up to 3 months. Defrost in the refrigerator before cutting and serving. You can also individually wrap the bars and freeze them too!

Ingredients

Cookie Dough Layer

  • 7 tablespoons (98 g) unsalted butter, room temperature
  • ¾ cup (150 g) light brown sugar
  • 2 tablespoons granulated sugar
  • 1 large egg, room temperature
  • 1 ¼ teaspoon pure vanilla extract
  • 1 cup plus 2 tablespoons (140 g) unbleached all-purpose flour
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup semi-sweet chocolate chips

Brownie Layer

  • 5 oz. semisweet chocolate chips
  • 6 tablespoons (85 g) unsalted butter, cold and cut into cubes
  • 2 ¼ tablespoons unsweetened cocoa powder
  • 2 large eggs, room temperature
  • 1 cup (200 g) granulated sugar
  • 1 ½ teaspoons pure vanilla extract
  • ½ teaspoon salt
  • ¾ cup (95 g) unbleached all-purpose flour
  • 16 regular or double stuff Oreos

Instructions 

  • Preheat oven to 350° F. Spray and 8×8 baking pan with nonstick cooking spray. Line with tin foil or parchment paper and spray again. Set aside.

Cookie Dough Layer

  • In a bowl, whisk together the flour, salt and baking soda. Set aside.
  • In a stand mixer fitted with a paddle attachment (or using a hand mixer), 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).

Brownie Layer

  • 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 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.

Assembly

  • Layer the cookie dough on the bottom of the prepared 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 managed 16).
  • Slowly pour the brownie batter on top of the Oreo layer and make sure it evenly layers on top.
  • Bake for 35 to 40 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!
