Brookie (Chocolate Chip Cookie and Brownie Bar)

The brookie is a dessert bar combining two classic treats: a rich chocolate brownie base topped with chocolate chip cookie dough. The brownie layer offers a moist, fudgy texture with cocoa flavor, while the cookie dough topping bakes to a golden, slightly chewy finish studded with chocolate chips. This layered dessert balances the deep chocolate taste of the brownie with the buttery sweetness of the cookie layer, creating a complex texture and flavor profile that’s satisfying to bite through.

Ingredients

Brownie Layer:
  • 3/4 cup butter (softened)
  • 1 cup sugar
  • 1/3 cup brown sugar
  • 2 large egg
  • 1 teaspoon vanilla
  • 1/2 cup cocoa powder unsweetened
  • 1 cup flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup chocolate chips (optional)
Chocolate Chip Cookie Layer:
  • 1/2 cup butter (softened)
  • 3/4 cup brown sugar
  • 1/4 cup sugar
  • 1 large egg
  • 1 teaspoon vanilla
  • 1 1/4 cups flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup chocolate chips (plus milk chocolate chunks to sprinkle on the top)

Instructions

Brownie Batter:
    Cup of Yum
  1. Preheat oven to 350 degrees. In a large mixing bowl, cream together butter, sugar, and brown sugar for 3-4 minutes or until light and fluffy. Add eggs one at a time, mixing well after each addition. Add vanilla.
  2. Stir in cocoa, flour, baking soda, and salt until mixed together. Fold in chocolate chips. Pour into 9 x 13 aluminum pan and spread evenly. DO NOT use a glass pan or the brookies will take so much longer to cook and will get hard on the edges and underbaked in the center.
Chocolate Chip Cookie Dough:
  1. In a large mixing bowl, cream together butter, brown sugar, and sugar for 3-4 minutes. Add egg and vanilla and mix for 1 minute longer.
  2. Stir in flour, baking soda, and salt. Fold in chocolate chips. Drop spoonfuls of cookie dough on top of the brownie batter, evenly, to try to cover most of it.
  3. Bake for 28 to 32 minutes or until the edges begin to set-up. If you are using milk chocolate chunks, sprinkle on the top the last 5 minutes of baking time. Once the bars are baked, let cool before cutting. To make it easier to cut, place the bars in the freezer for 20-30 minutes.

Notes

  • Use an aluminum pan rather than glass to ensure even cooking and avoid a hard crust or undercooked center.
  • The brookie combines rich chocolate brownie and chocolate chip cookie dough layers for contrasting textures in each bar.
