Fudgy Chewy Brookies (Printer-Friendly)

Rich fudgy brownie layer meets chewy chocolate chip cookie dough in this indulgent 55-minute dessert that yields 16 decadent squares.

# What You'll Need:

→ Brownie Layer

01 - 1/2 cup unsalted butter, melted
02 - 3/4 cup granulated sugar
03 - 1/2 cup plus 1 tablespoon packed light brown sugar
04 - 2 large eggs
05 - 1 teaspoon vanilla extract
06 - 1/2 cup plus 1 tablespoon all-purpose flour
07 - 1/3 cup unsweetened cocoa powder
08 - 1/2 teaspoon 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 teaspoon vanilla extract
15 - 1 cup all-purpose flour
16 - 1/2 teaspoon baking soda
17 - 1/2 teaspoon salt
18 - 3/4 cup semisweet chocolate chips

# How-To Steps:

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 is glossy and smooth.
03 - Sift the flour, cocoa powder, and salt directly into the wet ingredients. Stir gently just until combined — do not overmix. Fold in the 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, beat the softened butter with 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 small bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the butter mixture, stirring until just combined. Fold in the chocolate chips.
07 - Drop spoonfuls of the cookie dough evenly over the brownie layer. Gently spread and swirl with a spatula to cover — a few gaps are perfectly fine and create a beautiful marbled look.
08 - Bake for 28 to 32 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out with moist fudgy crumbs attached — not wet batter.
09 - Let the brookies cool completely in the pan before using the parchment overhang to lift them out. Cut into 16 even squares.

# Expert Hints:

01 -
  • You get two desserts in one bite, which is honestly the only math that matters.
  • The contrast between dense brownie bottom and golden cookie top is something no single dessert can replicate.
  • They freeze beautifully, so you can stash a few squares and forget about them until a Tuesday emergency strikes.
02 -
  • Underbaking slightly is far better than overbaking because these set up as they cool and nobody wants a dry brookie.
  • The swirl does not need to look perfect, and ragged gaps between cookie and brownie actually create the best texture contrast.
03 -
  • A light sprinkle of flaky sea salt on top before baking takes these from great to unforgettable with zero extra effort.
  • Let the brownie batter rest for five minutes after mixing before spreading, because it thickens slightly and becomes easier to layer evenly.
