Fudgy Chewy Brookies (Print View)

Rich brownie and cookie dough layers swirled together for a fudgy, chewy chocolate dessert bar.

# What You Need:

→ Brownie Layer

01 - 1/2 cup unsalted butter, melted
02 - 3/4 cup granulated sugar
03 - 1/2 cup plus 1 tbsp packed light brown sugar
04 - 2 large eggs
05 - 1 tsp vanilla extract
06 - 1/2 cup plus 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
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 the oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving enough overhang on the sides to lift the baked brookies out easily.
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 until the mixture is smooth and glossy. Sift in the flour, cocoa powder, and salt, then fold gently until just combined. Fold in the chocolate chips.
03 - Pour the brownie batter into the prepared pan and spread it into an even layer across the bottom.
04 - In a medium bowl, cream the softened butter with brown sugar and granulated sugar until light and fluffy. Beat in the egg and vanilla extract until fully incorporated.
05 - In a separate 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.
06 - Drop spoonfuls of the cookie dough evenly over the brownie layer. Gently spread and swirl to cover the surface, leaving some small gaps for a marbled effect.
07 - 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, not wet batter.
08 - Let the brookies cool completely in the pan before using the parchment overhang to lift them out. Cut into 16 even squares.

# Expert Tips:

01 -
  • You get two desserts in one pan, which feels like pulling off a magic trick at any potluck or gathering.
  • The contrast between the dense fudgy bottom and the chewy golden top is something no single dessert can replicate.
  • They freeze beautifully, so you can stash half the batch and surprise yourself weeks later.
02 -
  • Underbaking slightly is always better than overbaking because the brookies continue to set as they cool in the pan.
  • If the cookie dough feels too soft to handle, pop it in the fridge for ten minutes before dropping it on the brownie layer.
03 -
  • Sprinkle flaky sea salt over the top right before baking because the salty crunch against all that sweetness is genuinely transformative.
  • Let the brownie batter rest for five minutes after mixing before spreading it in the pan because the flour absorbs the liquid and the texture turns out fudgier.
