- 1/2 cup unsalted butter – softened
- 1/2 cup light brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 tsp baking soda
- 1/4 tsp fine salt
- 1 cup semisweet chocolate chips
- 1/2 cup unsalted butter – melted
- 1/2 cup unsweetened cocoa powder
- 1 cup granulated sugar
- 2 large egg
- 1 tsp vanilla extract
- 1/4 tsp fine salt
- 3/4 cup all-purpose flour
Instructions
1. Preheat the oven to 350°F (175°C). Line a 9-inch square baking pan with a parchment sling, leaving overhang on two sides for easy removal.
2. Make the cookie dough: In a large bowl, beat the softened butter, light brown sugar, and 0.25 cup granulated sugar until creamy and slightly lightened, 2–3 minutes. Beat in the egg and 1 tsp vanilla extract until smooth, 30–45 seconds.
3. In a separate bowl, whisk together 1.25 cups all-purpose flour, baking soda, and 0.25 tsp fine salt. Add the dry ingredients to the butter mixture and mix just until no dry spots remain. Fold in the semisweet chocolate chips. Press the dough evenly into the prepared pan to form a level base.
4. Make the brownie batter: In a medium bowl, whisk the melted butter and unsweetened cocoa powder until glossy. Whisk in 1 cup granulated sugar until evenly combined. Whisk in the eggs one at a time until the mixture is thick and shiny, then whisk in the remaining 1 tsp vanilla extract and remaining 0.25 tsp fine salt.
5. Sprinkle the 0.75 cup all-purpose flour over the batter and fold with a spatula just until no flour streaks remain; do not overmix. Spoon the brownie batter over the cookie layer and gently spread to the edges to cover without disturbing the base.
6. Bake until the top is set, the edges are slightly pulled away from the pan, and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter), 35–40 minutes.
7. Cool the pan on a wire rack until completely cool, about 1 hour. Lift out using the parchment, cut into 16 squares, and serve.
A brookie combines two beloved classics—chewy chocolate chip cookie and fudgy brownie—into one bar cookie with contrasting textures in every bite. The base brings caramel notes and gentle crispness from brown sugar and butter, while the brownie layer delivers deep chocolate richness and a tender, fudgy crumb. It’s a crowd-pleasing bake that travels well, cuts cleanly once cooled, and satisfies both cookie and brownie cravings at once.
Born from American home-baking culture’s love of mashups, the brookie rose to prominence in the early 2000s as bakeries and bloggers layered their favorite doughs and batters into a single pan. The concept echoes potluck bars and bake-sale squares that prioritize big flavor and easy sharing. Today, brookies are a staple in cafes and home kitchens, spawning countless riffs while retaining the simple joy of two classics baked together.
