1 large egg
1 teaspoon vanilla extract
½ teaspoon baking soda

¾ teaspoon fine sea salt
1 cup all-purpose flour
⅓ cup semi-sweet chocolate chips

Brownie Layer

5 tablespoons unsalted butter, melted
¼ cup unsweetened cocoa powder
1 large egg yolk

1 teaspoon vanilla extract
⅛ cup all-purpose flour
¼ teaspoon fine sea salt

Oreo Layer

4 Oreo cookies

Directions

1. Preheat the Oven

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy removal.

2. Make the Cookie Dough

In a bowl, cream together the brown sugar, granulated sugar, and softened butter until light and fluffy.

Add the egg and vanilla extract, mixing until combined.
Stir in the baking soda, sea salt, and flour until just combined. Fold in the chocolate chips.

3. Make the Brownie Batter

In a separate bowl, whisk together the melted butter and cocoa powder until smooth.

Add the egg yolk, vanilla extract, and sea salt. Stir in the flour until just combined.

4. Assemble the Brookies

Press the cookie dough evenly into the prepared pan to form the base layer.
Arrange the Oreos in a single layer on top of the cookie dough.

Spread the brownie batter over the Oreos, ensuring they are fully covered.

5. Bake

Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Allow the brookies to cool completely in the pan before lifting them out using the parchment overhang.

6. Slice and Serve

Slice into 16 squares and serve. Enjoy the chewy, fudgy, and crunchy layers in every bite!
