Ingredients

For the cookie layer:

1 cup unsalted butter, softened
1 cup brown sugar
½ cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2 ½ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon salt
1 ½ cups chocolate chips

Middle layer:

1 package Oreo cookies (about 24 cookies)

For the brownie layer:

1 cup unsalted butter, melted
1 ½ cups granulated sugar
3 large eggs
1 teaspoon vanilla extract
1 cup cocoa powder
1 cup all-purpose flour
½ teaspoon salt
½ teaspoon baking powder

Instructions

Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
Prepare the cookie layer. In a large bowl, cream butter, brown sugar, and granulated sugar until light and fluffy. Add eggs and vanilla, mixing well. Stir in flour, baking soda, and salt. Fold in chocolate chips. Press the cookie dough evenly into the bottom of the prepared pan.
Add the Oreo layer. Place Oreo cookies in a single layer on top of the cookie dough.
Make the brownie layer. In a separate bowl, mix melted butter and sugar. Add eggs and vanilla, stirring until combined. Mix in cocoa powder, flour, salt, and baking powder until smooth. Spread the brownie batter evenly over the Oreos.
Bake for 35–45 minutes, or until the top is set and a toothpick inserted comes out with a few moist crumbs.
Allow to cool completely before slicing for clean layers.

Tips for Perfect Slutty Brownies

Do not overbake — slightly underbaked brownies stay gooey and rich.

Let them cool fully before cutting to keep the layers neat.

Use parchment paper for easy removal.

For extra decadence, serve warm with vanilla ice cream.
