Delicious Brookies

1. Prepare Baking Pan and Preheat Oven

Grease a 13x9-inch baking pan with butter and line it with parchment paper. Preheat your oven to 350 degrees Fahrenheit.

2. Make the Brownie Layer

In a saucepan, melt 8 tablespoons of unsalted butter and mix in 1 cup of granulated sugar. Allow the mixture to cool slightly, then whisk in 2 large eggs and 1.5 teaspoons of vanilla extract. In a separate bowl, combine 0.5 cup of all-purpose flour, 0.75 cup of cocoa powder, 0.25 teaspoon of baking powder, and 0.25 teaspoon of kosher salt. Stir these dry ingredients into the buttery sugar mixture until just combined.

3. Make the Cookie Batter

In a clean saucepan, melt 6 tablespoons of unsalted butter. Stir in 1 cup of brown sugar. Once the mixture has cooled slightly, whisk in the remaining 2 large eggs and 2 teaspoons of vanilla extract. For the dry ingredients, mix 1.25 cups of all-purpose flour, 2 teaspoons of baking powder, and 0.75 teaspoon of kosher salt. Fold in 0.75 cup of chocolate chips into the smooth dough.

4. Assemble and Bake

Alternate dollops of brownie and cookie batters in the prepared pan. Sprinkle the remaining 0.5 cup of chocolate chips over the top. Bake in the preheated oven for 20-22 minutes, until a toothpick comes out with a few moist crumbs.

5. Cool and Serve

Allow the brookies to cool in the pan, then transfer to a rack to cool for about 45 minutes. Lift the brookies using the parchment paper, transfer to a cutting board, and cut into 24 bars.
