0.5cupunsalted butter, softened to room temperature
1cupbrown sugar, packed firmly
0.5cupgranulated sugar
1largeegg
1teaspoonpure vanilla extract
1cupsemi-sweet chocolate chips
1cupcookie dough (prepared from scratch or store-bought)
Instructions
Begin by preheating your oven to 350°F (175°C). Prepare an 8x8 inch baking pan by lining it with parchment paper, ensuring there’s some hanging over the sides for easier removal later.
In a medium mixing bowl, sift together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Set this bowl aside.
In a large mixing bowl, use an electric mixer or a sturdy whisk to cream together the softened butter, packed brown sugar, and granulated sugar until light and creamy.
Add in the large egg and pure vanilla extract to the butter-sugar mixture. Mix until smooth and well incorporated.
Gradually add the sifted dry ingredients to the wet mixture, stirring gently until just combined.
Fold in the semi-sweet chocolate chips, ensuring they are evenly dispersed throughout the brownie batter.
Pour the fudgy brownie mixture into your prepared baking pan, smoothing the top into an even layer.
Take spoonfuls of the cookie dough and drop them over the brownie layer, gently pressing them down into the batter.
Using a knife or skewer, create a gentle swirl by running it through the brownie batter and cookie dough for a marbled appearance.
Place the baking pan in the oven and bake for 25-30 minutes until the edges are firm and the center remains slightly soft.
Once done, allow the brookies to cool in the pan for about 15 minutes. Then, lift them out onto a wire rack to cool completely before slicing into squares.
Notes
Serve on a decorative platter and dust with powdered sugar for an indulgent touch.
