Rich dark chocolate brownie layered with chocolate chip cookie dough creates these decadent fudgy chewy bars.

# What You'll Need:

→ Brownie Layer

01 - 1/2 cup unsalted butter
02 - 1 cup dark chocolate, chopped
03 - 3/4 cup granulated sugar
04 - 2 large eggs
05 - 1 tsp vanilla extract
06 - 1/2 cup all-purpose flour
07 - 1/4 tsp salt

→ Cookie Layer

08 - 6 tbsp unsalted butter, softened
09 - 1/3 cup brown sugar
10 - 1/4 cup granulated sugar
11 - 1 large egg yolk
12 - 1 tsp vanilla extract
13 - 3/4 cup plus 1 tbsp all-purpose flour
14 - 1/2 tsp baking soda
15 - 1/4 tsp salt
16 - 1/2 cup semi-sweet chocolate chips

# How To Make It:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a heatproof bowl, melt butter and dark chocolate together over a pan of simmering water or in the microwave. Stir until smooth. Cool slightly.
03 - Whisk sugar into the chocolate mixture, then add eggs one at a time, followed by vanilla. Fold in flour and salt until just combined.
04 - Spread the brownie batter evenly into the prepared pan.
05 - In a medium bowl, cream softened butter with brown sugar and granulated sugar until light and fluffy.
06 - Beat in egg yolk and vanilla extract until well incorporated.
07 - Add flour, baking soda, and salt; mix until just combined. Fold in chocolate chips.
08 - Drop spoonfuls of cookie dough evenly over the brownie batter. Gently spread or swirl with a spatula for a marbled effect.
09 - Bake for 32 to 36 minutes, until the top is golden and a toothpick inserted in the center comes out with moist crumbs.
10 - Cool completely in the pan on a wire rack before slicing into squares.

# Expert Tips:

01 -
  • You get two desserts in every single bite with that perfect fudgy chewy contrast
  • The marble effect makes these look like you spent hours when they are actually quite simple
02 -
  • Slightly underbaking is your friend here, the residual heat finishes the cooking and keeps the texture fudgy
  • Room temperature ingredients are non negotiable for both layers to emulsify properly
03 -
  • If your brownie layer feels too thick to spread easily, warm your spatula under hot water and dry it off
  • For the cleanest cuts, use a sharp knife that has been dipped in hot water and wiped clean between each slice
