Instructions
Preheat the oven: Preheat oven to 350°F (175°C) and grease or line a 9x13-inch baking pan with parchment paper.
Mix in dry: Prepare the brownie layer by melting butter, stirring in sugar, and adding eggs and vanilla. Mix in the dry ingredients until just combined, then spread in the baking pan.
Blend in: Make the cookie layer by creaming butter and sugars, then adding the egg and vanilla. Blend in the dry ingredients, fold in chocolate chips, and spread over the brownie layer.
Swirl: Swirl the two layers slightly for a marbled effect if desired.
Bake: Bake for 30-35 minutes or until a toothpick comes out with a few moist crumbs. Cool on a wire rack for 15 minutes, then slice and serve.
Notes
Substitute chocolate chips with your favorite add-ins like white chocolate chips or peanut butter chips.
Add a pinch of espresso powder for enhanced flavor.
Variations and Twists:
S'mores Brookies: Add crushed graham crackers and mini marshmallows, then broil briefly.
Nutella Swirl: Add dollops of Nutella and swirl into the brownie layer.
Pumpkin Spice Brookies: Add pumpkin puree and spice for a fall twist.
Red Velvet Brookies: Use red velvet mix and add cream cheese frosting for a festive look.
Tips for Perfecting:
Don’t overmix to keep the brookies fudgy.
Use quality chocolate for better flavor.
Begin testing for doneness early to prevent overbaking.
Chill the cookie dough if possible for thicker, chewier brookies.
Experiment with additional layers like fruit preserves or peanut butter for added flavor.
