Description

Slutty Brownies are an indulgent and layered dessert combining a buttery chocolate chip cookie base, a rich layer of Oreo cookies, and a fudgy brownie topping. This decadent treat is baked until perfectly set and requires cooling for best texture, offering a delightful mix of chewy, crunchy, and gooey flavors in every bite.

Ingredients

Scale

Chocolate Chip Cookie Layer

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)

Oreo Layer

28 Oreo cookies

Brownie Batter

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

Preheat and prepare pan: Preheat the oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) baking pan, then line it with parchment paper allowing an overhang for easy removal.
Make chocolate chip cookie layer: In a large bowl, beat softened butter with brown sugar and white sugar until combined. Add the large egg, egg yolk (discard the second egg white), and vanilla extract, mixing well. On low speed, beat in the flour and salt until just combined. Stir in chocolate chips using a spatula. Spread this dough evenly in the prepared pan.
Add Oreo cookie layer: Arrange the 28 Oreo cookies over the cookie dough layer, pressing them slightly into the dough so they adhere well. Use whole and half cookies as needed to cover the surface completely.
Prepare brownie batter: Finely chop the dark chocolate. Place chopped chocolate and cubed butter in a heatproof bowl and microwave in 45-second intervals on medium power, stirring between intervals until melted and smooth. Let cool for 5 minutes. Whisk in eggs and granulated sugar until well combined. Sift in flour, cocoa powder, and salt, then whisk gently until just combined.
Assemble brownie layer: Spoon the brownie batter over the Oreo layer in several dollops. Gently spread the batter evenly across the Oreos with a spatula. This technique helps cover the Oreos without disturbing them.
Bake the brownies: Bake in the preheated oven for 37-45 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Baking time varies based on oven and desired gooeyness.
Cool and serve: Allow the brownies to cool completely, at least 4 hours, to set the layers. Use parchment paper overhang to lift the brownies from the pan, then cut into squares. Store leftovers at room temperature in an airtight container for up to 4 days.

Notes

Do not add two whole eggs to the cookie dough; use only one whole egg and one egg yolk to maintain texture.
Microwave chocolate and butter on medium power in intervals to avoid burning or graininess.
Use parchment paper with an overhang to easily remove the baked brownies from the pan.
Cooling the brownies fully ensures cleaner slicing and allows layers to set properly.
Adjust baking time depending on whether you prefer gooier or more set brownies.
