Ingredients

Scale

Brownie Batter

  • 1 cup (2 sticks) unsalted butter, melted and cooled slightly
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • ½ cup unsweetened cocoa powder
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup chocolate chips (optional, but highly recommended!)

Cookie Dough

  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 ¼ cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 cup chocolate chips
  • ½ cup chopped walnuts or pecans (optional)

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, lining the bottom with parchment paper for easy removal of the brookies.
  2. Mix Brownie Wet Ingredients: In a large bowl, whisk together the melted and cooled butter with granulated and brown sugars until well combined.
  3. Add Eggs and Vanilla to Brownie Base: Beat in the eggs one at a time, ensuring each is fully incorporated, then stir in vanilla extract.
  4. Combine Brownie Dry Ingredients: In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined to avoid overmixing.
  5. Add Chocolate Chips to Brownie Batter: Fold in chocolate chips if using, distributing them evenly through the batter.
  6. Spread Brownie Batter: Pour brownie batter into the prepared baking pan and spread it evenly with a spatula.
  7. Cream Cookie Dough Wet Ingredients: In a large bowl, cream together softened butter with granulated and brown sugars until light and fluffy.
  8. Add Eggs and Vanilla to Cookie Dough: Beat in the eggs one at a time followed by the vanilla extract.
  9. Combine Cookie Dough Dry Ingredients: In a separate bowl, whisk together flour, baking soda, and salt. Gradually add these dry ingredients to the wet cookie dough mixture, mixing just until combined to avoid tough dough.
  10. Add Chocolate Chips and Nuts to Cookie Dough: Stir in chocolate chips and chopped nuts if using.
  11. Drop Cookie Dough Over Brownie Batter: Using a spoon, drop spoonfuls of cookie dough evenly over the brownie batter in the pan.
  12. Create Marbled Effect: Gently swirl the cookie dough into the brownie batter using a knife or spatula to form a marbled pattern. Be careful not to over-swirl.
  13. Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  14. Cool: Allow the brookies to cool completely in the pan to set properly before cutting.
  15. Cut and Serve: Once cooled, cut the brookies into 16 squares and serve.

Notes

  • For easier removal, line the baking pan with parchment paper.
  • Avoid overmixing both batters to maintain the fudgy and chewy texture.
  • Chocolate chips and nuts are optional but highly recommended for extra flavor and texture.
  • Store brookies in an airtight container at room temperature for up to 3 days, or refrigerate for longer freshness.
  • Customize by using different types of chocolate chips—dark, milk, or white chocolate.
