Create the ultimate dessert bar by layering rich, fudgy brownie batter with chewy chocolate chip cookie dough. This recipe delivers the best of both worlds in one decadent, easy-to-make treat.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 1 3/4 cups granulated sugar
  • 3/4 cup packed light brown sugar
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 cup semi-sweet chocolate chips (for brownie layer)
  • 1 cup (1 batch) prepared chocolate chip cookie dough (store-bought or homemade)
  • 1/2 cup semi-sweet chocolate chips (for cookie layer)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper.
  2. Prepare the brownie batter: In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Beat in the eggs one at a time, then stir in the vanilla extract.
  3. In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the 1 cup of chocolate chips designated for the brownie layer.
  4. Spread half of the brownie batter evenly into the prepared pan.
  5. Dollop the chocolate chip cookie dough evenly over the brownie layer. Gently spread the cookie dough to cover the brownie layer, being careful not to mix the layers completely.
  6. Spoon the remaining brownie batter over the cookie layer. Use a knife or offset spatula to gently spread the top layer, ensuring most of the cookie dough is covered. Sprinkle the remaining 1/2 cup of chocolate chips over the top.
  7. Bake for 35 to 40 minutes. The edges should look set, and a toothpick inserted near the center should come out with moist crumbs attached, not wet batter.
  8. Let the brookies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang.
  9. Cut into squares. This layered dessert bar is best served once fully cooled for clean slices.

Notes

  • For a fudgier brownie texture, slightly underbake by about 2-3 minutes.
  • If you use homemade cookie dough, ensure it is chilled slightly before layering to prevent it from spreading too quickly into the brownie batter during baking.
  • For an extra decadent treat, press chopped peanut butter cups into the top layer before baking.
