Introduction

Slutty Brownies are the ultimate indulgence, layering a chocolate chip cookie base, Oreos in the middle, and rich brownie batter on top. This decadent dessert combines all your favorite treats in one pan, perfect for sharing or enjoying as a special treat.

A stack of three square layered dessert bars sits neatly on a white plate with a white marbled surface in the background. Each bar has three visible layers: the bottom is a light golden cookie dough with large chocolate chips scattered throughout; the middle is a whole dark Oreo cookie with visible white cream in the center; the top layer is a thick, rich, and slightly cracked dark chocolate brownie. The stack is carefully aligned, showing all layers clearly and the texture contrasts between the soft cookie dough, smooth cream, and dense brownie top. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

3/4 cup unsalted butter (168 grams), softened
1/2 cup brown sugar (105 grams)
1/2 cup white sugar (100 grams)
1 large egg
1 large egg yolk (discard the white)
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour (188 grams)
1/4 teaspoon salt
2/3 cups chocolate chips (120 grams)
28 Oreo cookies
1/2 cup unsalted butter (112 grams), cubed
6 oz dark chocolate (170 grams), 50-70% or semi-sweet
1 cup granulated sugar (200 grams)
2 large eggs
1/2 cup all-purpose flour (63 grams)
1/4 cup cocoa powder (23 grams)
1/2 teaspoon salt

Instructions

Step 1: Preheat the oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) pan, then line it with parchment paper leaving an overhang on the sides. Greasing first helps the paper stick.
Step 2: Prepare the chocolate chip cookie layer. In a large bowl, beat together softened butter, brown sugar, and white sugar until combined. Add the egg, egg yolk, and vanilla extract while beating. With the mixer on low, mix in the flour and salt. Turn off the mixer and fold in chocolate chips gently.
Step 3: Spread the cookie dough evenly into the prepared pan using a spatula.
Step 4: Arrange the Oreo cookies on top of the cookie dough, pressing them down slightly to cover the layer completely.
Step 5: Make the brownie batter by finely chopping the dark chocolate. Place it with the cubed butter in a heatproof bowl and microwave at medium power for 45-second intervals, stirring between each until melted and smooth. Let cool for 5 minutes.
Step 6: Whisk the eggs and granulated sugar into the cooled chocolate mixture. Sift together the flour, cocoa powder, and salt, then whisk them into the wet ingredients until just combined.
Step 7: Drop spoonfuls of the brownie batter over the Oreo layer, then spread gently and evenly with a spatula.
Step 8: Bake in the preheated oven for 37-45 minutes. The brownies are done when a toothpick inserted comes out with a few moist crumbs but no wet batter.
Step 9: Cool the brownies fully in the pan for at least 4 hours. Use the parchment paper overhang to lift them out before slicing and serving.

Tips & Variations

For easier spreading, drop brownie batter in spoonfuls rather than pouring it all at once over the Oreos.
Use semi-sweet or bittersweet chocolate for a richer brownie layer.
Swap Oreos for another sandwich cookie if desired, or add nuts to the brownie batter for extra crunch.
Make sure to fully cool the brownies before slicing to keep clean edges and prevent sticking.

Storage

Store leftover Slutty Brownies in an airtight container at room temperature for up to 4 days. They reheat well slightly warmed in the microwave for a few seconds or can be enjoyed cold.
