Ingredients
Scale
1 cup (2 sticks) unsalted butter, softened
1 1/2 cups granulated sugar
3/4 cup packed brown sugar
4 large eggs
1 tablespoon vanilla extract
1 1/4 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1/2 teaspoon baking powder
1/2 teaspoon salt
1 cup semi-sweet chocolate chips (for brownie batter)
1 cup semi-sweet chocolate chips (for cookie batter)
1 cup all-purpose flour (for cookie batter)
1/2 teaspoon baking soda (for cookie batter)
1/4 teaspoon salt (for cookie batter)
1/2 cup (1 stick) unsalted butter, softened (for cookie batter)
1/2 cup granulated sugar (for cookie batter)
1/4 cup packed brown sugar (for cookie batter)
1 large egg (for cookie batter)
1 teaspoon vanilla extract (for cookie batter)
Instructions
Preheat your oven to 350 degrees Fahrenheit. Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the long sides for easy removal.
Prepare the brownie layer: In a large bowl, cream together 1 cup softened butter, 1 1/2 cups granulated sugar, and 3/4 cup brown sugar until light and fluffy. Beat in 4 eggs one at a time, then mix in 1 tablespoon vanilla extract.
In a separate bowl, whisk together 1 1/4 cups flour, cocoa powder, baking powder, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in 1 cup of chocolate chips. Spread this brownie batter evenly into the prepared pan.
Prepare the cookie layer: In a medium bowl, cream together 1/2 cup softened butter, 1/2 cup granulated sugar, and 1/4 cup brown sugar. Beat in 1 egg and 1 teaspoon vanilla extract.
In another bowl, whisk together 1 cup flour, baking soda, and 1/4 teaspoon salt. Gradually add the dry ingredients to the wet ingredients. Mix until just combined. Fold in the remaining 1 cup of chocolate chips.
Drop spoonfuls of the cookie dough randomly over the top of the brownie batter layer. Use a knife or offset spatula to gently spread the cookie dough to cover the brownie layer as much as possible, creating a swirl effect.
Bake for 30 to 35 minutes. The edges should look set, and a toothpick inserted near the center should come out with moist crumbs attached, not wet batter.
Let the brookies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. Cut into squares.
Notes
For a fudgier brownie layer, slightly reduce the amount of flour in the brownie batter by one tablespoon.
To achieve distinct layers, chill the brownie batter for 15 minutes before spreading it in the pan.
If you prefer a stronger swirl, reserve 1/4 cup of the brownie batter and dollop it over the cookie layer before baking.
