Can’t decide between cookies and brownies? These cookie bars let you get the best of both worlds, with the chewy, buttery texture of a cookie and the deeply chocolatey deliciousness of a brownie.



  • ½ cup butter
  • 1 cup packed brown sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1 ¼ cups flour
  • ⅓ cup dutch processed cocoa powder
  • ½ tsp baking soda
  • ½ tsp salt
  • ½ cup white chocolate chips, divided
  • ½ cup milk chocolate chips, divided


  1. Preheat oven to 350F. Lightly grease a 9×13” baking pan, and line with parchment paper.
  2. In a large mixing bowl, cream together the butter and brown sugar. Add the egg and vanilla extract, and beat until smooth.
  3. In a small mixing bowl, stir together the flour, cocoa powder, baking soda and salt. Add to the wet ingredients, and stir until just barely combined. Fold in 1/3 cup each of the white and milk chocolate chips.
  4. Press the dough into the prepared pan, and sprinkle with the remaining white and milk chocolate chips. Bake in preheated oven for 20-25 minutes, or until the edges are set and the middle is slightly puffed. Let cool in the pan on a wire rack for 1 hour, then gently lift out using the parchment and cut into bars. Store in an airtight container until ready to serve.
