Ingredients for Slutty Brownies recipe
Cookie Layer (Base)
- ½ cup (115 g) unsalted butter, melted
- ¾ cup (150 g) packed light brown sugar
- ¼ cup (50 g) granulated sugar
- 1 large egg
- 1 large egg yolk
- 2 teaspoons vanilla extract
- 1½ cups (190 g) all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1¼ cups (225 g) chocolate chips

Oreo Layer (Middle)
- 18 Oreo cookies (classic or double-stuffed; double-stuffed is recommended for extra indulgence)
Brownie Layer (Top)
- 1 box brownie mix (plus ingredients required by the box, usually oil, eggs, and water)
Equipment Needed
- 9×9-inch (23×23 cm) baking pan
- Parchment paper
- Large mixing bowls
- Silicone spatula
- Measuring cups and spoons
- Optional: small offset spatula for spreading layers
Step-by-Step Instructions
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, making sure the paper extends over the edges of the pan to allow easy removal of the finished brownies. Set aside while you prepare the layers.
Step 2: Make the Cookie Dough Base
In a large mixing bowl, combine the melted butter, light brown sugar, and granulated sugar. Stir using a silicone spatula until smooth and well incorporated.
Add the egg, egg yolk, and vanilla extract to the sugar mixture and mix thoroughly. The dough should be shiny and slightly thick.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix, as this can affect the chewy texture of the cookie layer.
Finally, fold in the chocolate chips evenly throughout the dough. Once fully incorporated, scrape the dough into the prepared baking pan. Use your spatula or hands to gently pat it into an even layer, pressing it into the corners so it forms a uniform base.
Step 3: Add the Oreo Layer
Place the Oreo cookies evenly over the cookie dough layer. You can leave them whole or slightly break them up to ensure every bite has a little bit of Oreo. Gently press the cookies into the dough so they stay in place during baking. This layer will provide a delightful crunch and creaminess contrast between the cookie base and the brownie topping.
Step 4: Prepare the Brownie Layer
Prepare your boxed brownie mix according to the package instructions. Most mixes require combining the brownie mix with oil, eggs, and water. Stir until smooth and glossy.
Carefully pour the brownie batter over the Oreo layer, spreading it evenly with a silicone spatula. Make sure the Oreo cookies are fully covered. The chocolate layer should be thick enough to provide a rich fudgy topping without overwhelming the other layers.
Step 5: Bake the Slutty Brownies
Place the baking pan in the preheated oven. Bake for 45–55 minutes, depending on your oven and the brownie mix used. The edges should be set, and the center should look slightly underdone. The brownies will continue to set as they cool, which helps maintain their gooey texture. Avoid overbaking, as this will make the brownies dry and compromise the chewy layers.

Step 6: Cool and Slice
Once baked, remove the pan from the oven and allow it to cool completely at room temperature. For cleaner slices, chill the brownies in the refrigerator for at least 30 minutes. Use a sharp knife to cut into squares. The layers should remain distinct, showcasing the chewy cookie base, Oreo middle, and fudgy brownie top.
Tips and Tricks for Perfect Slutty Brownies
- Use double-stuffed Oreos for extra creaminess in the middle layer.
- Don’t overmix the cookie dough to maintain a soft, chewy texture.
- Chill before slicing to prevent the layers from sliding and to achieve neat squares.
- Customize the layers: swap Oreos for peanut butter cups, Nutella, or caramel for a different flavor profile.
- Storage: These brownies can be stored at room temperature for up to 3 days, in the fridge for 5–6 days, or frozen for up to 2 months. Reheat slightly before serving if desired.
