Ingredients

For the Brownie Layer:

1/2 cup (1 stick) unsalted butter (melted)
1 cup semi-sweet chocolate chips
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/2 cup all-purpose flour
1/4 cup unsweetened cocoa powder
1/4 teaspoon salt

For the Cookie Layer:

1/2 cup (1 stick) unsalted butter (softened)
1/2 cup granulated sugar
1/2 cup brown sugar (packed)
1 large egg
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon salt
1 cup chocolate chips
12 Oreo cookies (halved)

Instructions

Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

Step 2: In a medium bowl, combine the melted butter and semi-sweet chocolate chips. Stir until smooth. Add the granulated sugar, eggs, and vanilla extract, mixing until well combined. Stir in the flour, cocoa powder, and salt until just combined. Pour the brownie batter evenly into the prepared pan.

Step 3: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Beat in the egg and vanilla extract until well combined. In a separate bowl, whisk the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the chocolate chips.

Step 4: Spoon the cookie dough over the brownie layer in the pan, spreading it evenly. Press the halved Oreo cookies gently into the top of the cookie dough.

Step 5: Bake for 30 to 35 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.

Step 6: Allow the brookies to cool in the pan for 10 to 15 minutes, then transfer to a wire rack to cool completely. Cut into squares and enjoy!

Tips & Variations

For extra richness, use dark chocolate chips instead of semi-sweet in the brownie layer.

Press Oreos lightly to avoid pushing them too deep into the cookie dough.

Add a pinch of espresso powder to the brownie batter to enhance the chocolate flavor.

Try substituting peanut butter chips for some of the chocolate chips in the cookie layer for a twist.

FAQs

Can I use regular chocolate chip cookie dough instead of making it from scratch?

Yes, you can use pre-made cookie dough for convenience, but homemade dough gives better texture and flavor balance in this recipe.

How do I know when the brookies are fully baked?

The edges should be set and a toothpick inserted into the center will come out with a few moist crumbs but no wet batter. Avoid overbaking to keep brookies soft and chewy.
