Description

Chocolate chip cookie brownie bars are two classic desserts in one! This tried-and-tested recipe for layered brookie bars is easy to make at home. Top the dark chocolate brownie batter with chocolate chip cookie dough, and bake until fudgy! Recipe makes 16 dessert bars.

Ingredients

Cookie Layer

  • 1 cup (140 g) all-purpose flour
  • 1/4 tsp cornstarch
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 6 Tbsp (84 g) unsalted butter, melted and slightly cooled
  • 1/4 cup (50 g) granulated sugar
  • 1/4 cup (50 g) light brown sugar
  • 1 large egg (50 g)
  • 1/2 tsp (2 g) vanilla extract
  • 1/2 cup (85 g) semisweet chocolate chips

Brownie Layer

  • 3/4 cup (168 g) unsalted butter, cubed
  • 1 1/3 cups (267 g) granulated sugar
  • 3/4 cup (72 g) Dutch process unsweetened cocoa powder
  • 1/4 tsp (1.5 g) salt
  • 1 large egg (50 g), at room temperature
  • 1 large egg yolk (18 g), at room temperature
  • 1 1/2 tsp (6 g) vanilla extract
  • 1/2 cup (70 g) all-purpose flour
  • 3/4 cup (128 g) semisweet chocolate chips

Topping

  • 2 Tbsp (21 g) semisweet chocolate chips
  • flaky salt

Instructions

  1. Preheat oven to 350°F and spray an 8-inch square metal baking pan lightly with nonstick spray. Line the pan with parchment paper.
  2. Make cookie layer: Whisk together flour, cornstarch, baking soda, and salt in a small bowl. Combine melted butter and sugars in a medium mixing bowl and whisk until incorporated. Whisk in egg and vanilla until smooth. Fold in flour mixture just until incorporated (no flour streaks remain). Fold in chocolate chips. Set dough aside.
  3. Make brownie layer: Melt butter in a medium saucepan over low heat. Once melted, whisk in sugar for 30 seconds until incorporated. Whisk in cocoa powder and salt until combined – the texture will appear granular at this point. Remove saucepan from the heat and let stand for 5 minutes. Whisk in egg and egg yolk one at a time, until completely incorporated and batter is thick and shiny. Whisk in vanilla extract. Add flour and fold in just until no streaks remain. Fold in chocolate chips.
  4. Assemble bars: Spread brownie batter into prepared pan and smooth top with an offset spatula. Tap pan sharply several times to remove air bubbles. Drop spoonfuls of cookie dough evenly over brownie batter (don’t worry about a completely even layer of dough). Sprinkle top with chocolate chips, pressing gently to adhere.
  5. Bake bars: Bake for 25 minutes, then loosely tent the pan with foil and bake another 15 minutes (for a total baking time of 40 minutes), until top and edges are golden and a toothpick comes out with a few moist crumbs. Remove from oven and sprinkle with flaky salt. Cool completely in baking pan on a wire rack.
  6. Lift parchment to remove brookies from pan and place on a cutting board; cut into squares with a sharp knife. Store in an airtight container at room temperature.

Equipment

Notes

Baking pan: A light metal baking pan is best for cookie bars and brownies. Do not use a glass or ceramic baking dish – they conduct heat much more slowly, resulting in uneven baking.
