Ingredients:
2 cups unsalted butter, softened
2 cups granulated sugar
3 large eggs
2 teaspoons vanilla extract
1/3 cup unsweetened cocoa powder
2 cups all-purpose flour
1/4 teaspoon salt
1/2 teaspoon baking powder
1/2 cup brown sugar, packed
1/2 teaspoon baking soda
1 cup chocolate chips
Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper or lightly grease it.
Make the Brownie Layer:
In a large mixing bowl, cream together the softened unsalted butter and granulated sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
In another bowl, whisk together the cocoa powder, all-purpose flour, salt, baking powder, and baking soda.
Gradually add the dry mixture to the wet ingredients and mix until just combined.
Fold in half of the chocolate chips.
Pour the brownie batter into the prepared pan and spread it evenly.
Make the Cookie Dough Layer:
In a separate bowl, cream together the remaining unsalted butter, brown sugar, and granulated sugar until fluffy.
Add the eggs and vanilla extract, mixing until well combined.
In another bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients and mix until just combined.
Fold in the remaining chocolate chips.
Assemble the Brookies:
Drop spoonfuls of the cookie dough over the brownie layer, spacing them out evenly.
Use a spatula or knife to gently swirl the two layers together for a marbled effect.
Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
Cool and Serve: Allow the brookies to cool in the pan for at least 10-15 minutes before cutting into squares.
