Brookies are a delicious dessert that combines two classic treats: brownies and cookies. These brownie cookie bars feature a layer of fudgy brownie and chocolate chip cookie.
Line a 9”x13” pan with parchment paper and spray with nonstick cooking spray.
Prepare the brownie mix according to the package directions, then pour the batter into the prepared pan and spread it along the bottom of the pan until it’s in an even layer.
Make the cookie layer by creaming the butter, brown sugar, and granulated sugar in a bowl (use a hand mixer or stand mixer fitted with a paddle attachment). Add the egg and vanilla and mix again. Add the flour, cornstarch, baking powder, baking soda, and salt and mix to combine. Lastly, stir in the chocolate chips.
Use your hands to portion the cookie dough over the top of the brownie batter. The cookie dough will cover most of the brownie batter, but if there areas that the brownie batter is peaking through, that’s fine!
Cover with foil and bake for 20 minutes. Then uncover and bake for an additional 20 minutes.
Remove from the oven and let cool completely before slicing and serving.
