Instructions

  1. Step 1: Preheat oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. Step 2: In a medium bowl, whisk together 2 cups all-purpose flour, 1/2 cup unsweetened cocoa powder, 1 tsp baking powder, and 1/2 tsp salt.
  3. Step 3: In a large bowl, whisk 1 cup melted unsalted butter, 1 cup granulated sugar, and 1/2 cup packed light brown sugar until combined; add 2 large eggs and 2 tsp vanilla extract, whisking until smooth.
  4. Step 4: Gradually add the dry ingredients to the wet ingredients, stirring until just combined, then fold in 1/3 cup dark chocolate chips, 1/3 cup milk chocolate chips, and 1/3 cup white chocolate chips.
  5. Step 5: Spread the batter evenly into the prepared pan and bake for 25-28 minutes until the edges are set but the center remains slightly soft.
  6. Step 6: Allow bars to cool completely in the pan on a wire rack before lifting out with parchment paper and cutting into 12 squares.
