Fudgy Chewy Brookies (Printable)

Fudgy brownie meets chewy cookie in these decadent layered chocolate dessert bars.

# What You Need:

→ Brownie Layer

01 - 1/2 cup unsalted butter, melted
02 - 3/4 cup granulated sugar
03 - 1/2 cup + 1 tbsp packed light brown sugar
04 - 2 large eggs
05 - 1 tsp vanilla extract
06 - 1/2 cup + 1 tbsp all-purpose flour
07 - 1/3 cup unsweetened cocoa powder
08 - 1/2 tsp salt
09 - 2/3 cup semisweet chocolate chips

→ Cookie Layer

10 - 1/2 cup unsalted butter, softened to room temperature
11 - 1/2 cup light brown sugar
12 - 1/4 cup granulated sugar
13 - 1 large egg
14 - 1 tsp vanilla extract
15 - 1 cup all-purpose flour
16 - 1/2 tsp baking soda
17 - 1/2 tsp salt
18 - 3/4 cup semisweet chocolate chips

# How To Make It:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a large bowl, whisk the melted butter with granulated sugar and brown sugar until well combined. Add the eggs and vanilla extract, whisking vigorously until the mixture turns glossy and smooth.
03 - Sift the flour, cocoa powder, and salt directly into the wet mixture. Stir gently until just combined — do not overmix. Fold in the semisweet chocolate chips.
04 - Pour the brownie batter into the prepared pan and spread it into an even layer across the bottom.
05 - In a medium bowl, cream the softened butter with light brown sugar and granulated sugar using a hand mixer until light and fluffy, about 2 minutes. Beat in the egg and vanilla extract until fully incorporated.
06 - In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry mixture to the butter mixture, stirring until just combined. Fold in the chocolate chips.
07 - Drop spoonfuls of cookie dough evenly over the brownie batter. Gently spread and swirl the cookie dough to partially cover the brownie layer — some gaps are expected and desirable for a marbled effect.
08 - Bake for 28 to 32 minutes, until the top is lightly golden and a toothpick inserted into the center comes out with moist fudgy crumbs clinging to it — not wet batter.
09 - Let the brookies cool completely in the pan on a wire rack. Use the parchment overhang to lift the block out, then cut into 16 even squares.

# Expert Suggestions:

01 -
  • The fudgy bottom meets chewy top situation is genuinely unfair to every other dessert in your repertoire.
  • It solves the eternal brownie versus cookie debate without anyone having to choose a side.
  • You get two completely different textures from a single pan, which feels like getting away with something sneaky and wonderful.
02 -
  • Underbaking slightly is far better than overbaking, because the brownie layer should be fudgy and dense, not dry and cakey, so pull the pan when the center still looks just barely set.
  • The cookie dough will seem like it is not enough to cover the brownie layer, but trust the process and spread it in patches because it spreads during baking.
03 -
  • Weigh your ingredients with a kitchen scale if you have one, because the difference between a fudgy brownie and a dry one can come down to a few tablespoons of flour.
  • Let the melted butter cool slightly before mixing it with the sugars, since hot butter can scramble the eggs and give you a grainy texture instead of a silky one.
