  • 1 cup all-purpose flour + 2 TBSP flour
  • 1/4 cup cocoa powder
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup butter softened
  • 1 cup semi-sweet chocolate chips
  • 2 eggs
  • 2/3 cup brown sugar
  • 1/2 cup granulated sugar
  • 1 tsp vanilla extract

Chocolate Ganache

  • 6 oz semi-sweet chocolate chips
  • 1/4 cup heavy cream
  • 1/4 cup Rainbow Candy Chips


  • Preheat the oven to 350 degrees. Use parchment paper or a silpat mat to line a baking sheet.
  • Mix flour, cocoa powder, baking powder and salt in a small bowl and set aside.
  • Melt the butter and chocolate chips in a saucepan over low-medium heat. Stir continuously until melted. Remove from heat and set aside.
  • In stand mixer, beat eggs, brown sugar and granulated sugar on high speed for 3-4 minutes until the mixture is light and airy.
  • *You want to do these next steps by hand. Slowly add in the chocolate and butter mixture to the egg mixture in the mixing bowl and fold together with a spatula. Slowly add in the dry ingredients and continue to fold together with spatula until just combined.
  • Divide cookie dough into 12 equal sized cookie dough balls and place them on your prepared baking sheet. Put 6 cookies per baking sheet. (This recipe makes BIG cookies, so if you'd like smaller cookies, divide dough into 18 cookies.)
  • Bake cookies at 350 degrees for 12 minutes (about 10 minutes if you make smaller cookies!).
  • Remove from oven and let cookies cool on baking sheet for 10 minutes. Remove to cooling rack and let the cookies cool completely.

Make Chocolate Ganache

  • Add chocolate chips and heavy cream to a small, microwave-safe bowl and microwave for 30 second increments (stir between increments) until completely melted and smooth.
  • Spoon 1-2 tablespoons of chocolate ganache on top of each brownie cookie and sprinkle with Rainbow Candy Chips.
