Slutty Brownies Recipe with Oreo and Cookie Dough
These Slutty Brownies layer cookie dough, Oreo cookies, and brownie batter into a fudgy dessert bar that’s rich, chewy, and easy to make.

If you love a dessert with a little drama, these Slutty Brownies bring it in the best way. You get soft cookie dough on the bottom, a neat layer of Oreos in the middle, and rich brownie batter baked over the top. The result is thick, fudgy, and full of that satisfying contrast between chewy, creamy, and chocolatey. Ready for a pan dessert that makes people stop talking for a second and just take another bite?
This is the kind of layered dessert that feels playful but still easy enough for a weeknight bake. The cookie base gives you a buttery, tender bite, the Oreos add a crisp center, and the brownie layer bakes into a soft, gooey top. One thing can go wrong here: if you overbake, the center can turn dry instead of fudgy. To fix that, pull the pan when the top is set and a toothpick comes out with moist crumbs, not wet batter. Let’s walk through it so your bars slice cleanly and stay rich in the middle.
Why My Recipe
- Uses a simple cookie dough base for rich, chewy texture.
- Layers in Oreos for a crisp, creamy middle that holds its shape.
- Keeps the brownie layer fudgy by baking just until set.
- Makes 12 sturdy dessert bars for sharing or storing.

Ingredient Notes
- 1/2 cup unsalted butter, softened: Softened butter creams smoothly with the sugars and helps create a tender cookie base.
- 1/2 cup granulated sugar: Adds sweetness and helps the cookie layer bake up with a slight bite at the edges.
- 1/2 cup packed light brown sugar: Brings moisture and a deeper caramel note to the cookie dough.
- 1 large egg: Binds the cookie dough and adds structure.
- 1 teaspoon vanilla extract: Rounds out the flavor and gives the dessert a warm bakery-style aroma.
- 1 1/4 cups all-purpose flour: Provides the structure for the cookie layer.
- 1/2 teaspoon baking soda: Helps the cookie dough spread and bake with a lighter texture.
- 1/4 teaspoon salt: Balances the sweetness and sharpens the chocolate flavor.
- 3/4 cup semi-sweet chocolate chips: Adds extra chocolate pockets throughout the cookie layer.
- 24 Oreo cookies: Forms the signature middle layer and keeps the dessert fun and distinct.
- 1 box brownie mix, about 18 to 19 ounces: Use your preferred brownie mix for the top layer.
- Ingredients needed to prepare brownie mix, typically eggs, oil, and water, according to package directions: Have these ready before you start so the brownie batter comes together quickly.

Instruction Steps
- Heat the oven to 350°F and prepare a 9×13-inch baking pan with parchment paper or a light coating of grease. This helps the bars release cleanly later, which matters because the layers are thick and rich.
- In a medium bowl, beat the softened butter with the granulated sugar and brown sugar until the mixture looks smooth and fully combined. This step builds the base for the cookie layer, so take a minute to work out any lumps.
- Stir in the egg and vanilla until the mixture looks uniform. You want the batter to turn glossy and cohesive before adding the dry ingredients.
- Add the flour, baking soda, and salt, then mix just until a soft dough forms. Overmixing can make the cookie layer tough, so stop as soon as you no longer see dry flour.
- Fold in the chocolate chips so they stay evenly distributed through the dough.
- Press the cookie dough into an even layer across the bottom of the pan. Try to make the surface level so the Oreo layer sits neatly on top.
- Arrange the 24 Oreo cookies in a single layer over the cookie dough. Cover the surface as evenly as possible so every slice gets that middle cookie crunch.
- Prepare the brownie mix according to the package directions in a separate bowl. Follow the package measurements for the eggs, oil, and water so the batter bakes correctly.
- Pour the brownie batter over the Oreos and spread it gently to the edges of the pan. Work slowly here so you don’t shift the Oreo layer too much.
- Bake for 30 to 35 minutes, checking for a set top and a toothpick with moist crumbs near the center. That gives you the fudgy texture these bars are known for without drying them out.
- Let the brownies cool completely in the pan before lifting them out and slicing into squares. Cooling helps the layers firm up, so your cuts come out cleaner and the bars hold together better.
