Ingredients Overview
These Slutty Brownies use simple ingredients that create the perfect balance of chewy texture, rich chocolate flavor, and fudgy consistency.
Chocolate Chip Cookie Layer
Unsalted Butter
Softened butter creates a rich, buttery flavor and helps give the cookie layer its soft and chewy texture. Using unsalted butter allows better control over the final flavor.
Brown Sugar
Brown sugar adds moisture, caramel-like sweetness, and a chewy texture to the cookie base.
Granulated Sugar
White sugar balances the sweetness and helps create the classic chocolate chip cookie texture.
Egg and Egg Yolk
The egg binds the ingredients together, while the extra egg yolk adds richness and creates a softer, chewier cookie layer.
Vanilla Extract
Vanilla enhances the overall flavor and adds warmth to the cookie dough.
All-Purpose Flour
Flour provides structure and creates the perfect cookie base. Measuring accurately helps prevent a dry texture.
Salt
Salt balances the sweetness and enhances the chocolate flavors.
Chocolate Chips
Chocolate chips add extra pockets of melted chocolate throughout the cookie layer.

The Oreo layer adds a delicious cookie crunch and creates the signature layered look of these brownies. You can use regular Oreos or try flavored versions for easy recipe variations.
Brownie Layer
Unsalted Butter
Butter adds richness and helps create a smooth, fudgy brownie texture.
Dark Chocolate
Melted dark chocolate gives the brownies a deep chocolate flavor and luxurious texture.
Granulated Sugar
Sugar provides sweetness and helps create the classic brownie texture.
Eggs
Eggs add structure while keeping the brownies moist and fudgy.

How to Make Slutty Brownies
Follow this step-by-step recipe to create these incredible layered brownies.
1. Prepare the Baking Pan
Preheat your oven to 350°F (180°C). Lightly grease a 9×13-inch baking pan, then line it with parchment paper, leaving some overhang on the sides for easy removal.
Greasing the pan first helps the parchment paper stay in place while baking.
2. Make the Chocolate Chip Cookie Layer
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth and combined.
Add the egg, egg yolk, and vanilla extract. Mix until fully incorporated.
Gradually add the flour and salt, mixing until a soft cookie dough forms. Fold in the chocolate chips until evenly distributed.
Press the cookie dough evenly into the bottom of the prepared pan.
3. Add the Oreo Layer
Arrange the Oreo cookies in a single layer over the cookie dough. Press them gently into the dough so they stay in place while baking.
4. Prepare the Brownie Batter
Melt the butter and dark chocolate together until smooth. Allow the mixture to cool slightly.
In a separate bowl, whisk together sugar and eggs until combined. Add the melted chocolate mixture and mix well.
Fold in the flour, cocoa powder, and salt until just combined. Avoid overmixing to keep the brownies fudgy.
5. Add the Brownie Layer
Pour the brownie batter over the Oreo layer and spread evenly with a spatula.
6. Bake the Brownies
Bake for about 50 minutes, or until the center is set and a toothpick inserted into the brownie layer comes out with a few moist crumbs.
Avoid overbaking because the brownies continue to set as they cool.
7. Cool and Slice
Allow the brownies to cool completely before slicing. For cleaner cuts, chill them slightly before cutting into squares.
