Preparation

Set the rack in the middle of the oven and preheat to 350°F. Line a 13x9x2-inch pan with parchment paper and grease with butter or nonstick cooking spray.

Place the butter in a medium microwave-safe bowl and melt in the microwave until bubbling. Add the chocolate and whisk until the chocolate is completely melted.

Whisk in the granulated sugar, brown sugar, vanilla, and salt. The mixture will be a bit grainy; that’s okay. Whisk in the eggs. Finally, whisk in the flour until combined. Pour the batter into the prepared pan and spread evenly with a spatula. Set aside.

In the bowl of an electric mixer fitted with the paddle or beaters, beat the butter and both sugars for 3 minutes, or until light and fluffy. Scrape down the sides and bottom of the bowl as necessary. Add the vanilla and egg and beat for 1 minute more.

Scrape down the sides of the bowl again. Add the salt, baking powder, and baking soda and beat briefly until evenly combined. At a low speed, mix in the flour. Finally, add the chocolate chips and mix until just combined.

Dollop small spoonfuls of the cookie dough evenly over the brownie batter. Cover the pan with aluminum foil and bake for 20 minutes.

Remove the foil and continue baking for about 20 minutes more until the brownie edges are shiny and the cookie portion is golden brown. Transfer the pan to a wire rack and cool completely.

To cut, lift the brookies out of the pan using the parchment overhang and transfer them to a cutting board. Pull the parchment away from the edges. Using a sharp knife, cut the brookies into 2-inch squares directly on the parchment.

Serve and enjoy.
