Fudgy Chewy Brookies Bars (Printable)

Brownie base topped with a chewy chocolate-chip cookie layer for fudgy, shareable chocolate bars.

# What You'll Need:

→ Brownie Layer

01 - 1/2 cup (115 g) unsalted butter, melted
02 - 1 cup (200 g) granulated sugar
03 - 2 large eggs
04 - 1 tsp vanilla extract
05 - 1/2 cup (65 g) all-purpose flour
06 - 1/3 cup (30 g) unsweetened cocoa powder
07 - 1/4 tsp salt

→ Cookie Layer

08 - 1/2 cup (115 g) unsalted butter, softened
09 - 1/2 cup (100 g) packed brown sugar
10 - 1/4 cup (50 g) granulated sugar
11 - 1 large egg
12 - 1 tsp vanilla extract
13 - 1 1/4 cups (150 g) all-purpose flour
14 - 1/2 tsp baking soda
15 - 1/2 tsp salt
16 - 2/3 cup (110 g) chocolate chips

# Directions:

01 - Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a medium bowl, whisk together the melted butter and granulated sugar until well combined. Add the eggs and vanilla extract, whisking until the mixture is smooth and glossy. Fold in the flour, cocoa powder, and salt until just incorporated. Spread the batter evenly across the bottom of the prepared baking pan.
03 - In a separate bowl, beat the softened butter, brown sugar, and granulated sugar together until light and creamy. Mix in the egg and vanilla extract until fully blended. In another bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in the chocolate chips.
04 - Drop spoonfuls of the cookie dough evenly over the brownie batter. Gently spread with a spatula to cover the surface — it is fine if some brownie batter peeks through.
05 - Bake for 28–33 minutes, or until the cookie layer is golden and a toothpick inserted into the center comes out with a few moist crumbs. Avoid overbaking to maintain a fudgy texture.
06 - Allow the brookies to cool completely in the pan. Use the parchment overhang to lift the block out, then cut into 16 even bars.

# Expert Tips:

01 -
  • You get the dense fudgy center of a brownie and the golden chewy edge of a cookie in every single bite, no compromise required.
  • It looks like you spent hours layering something fancy, but the whole thing comes together with basic bowls and a spatula.
02 -
  • Overbaking is the single biggest enemy of brookies because the brownie layer goes from fudgy to dry in just a few extra minutes, so set a timer and check early.
  • Chilling the baked brookies for an hour before slicing firms up the layers and gives you those clean bakery style edges everyone photographs.
03 -
  • Use a toothpick to test the center at 26 minutes and then every two minutes after, because ovens vary wildly and the difference between perfect and overdone is surprisingly small.
  • Let the brownie batter rest for five minutes before spreading it in the pan because it thickens slightly and creates a denser chewier final texture.
