Equipment

  • 9x9 inch baking pan
  • Parchment paper
  • 2 mixing bowls
  • Small saucepan
  • Whisk

Ingredients
  

Main Ingredients

  • ¾ cup all purpose flour
  • ⅔ cup unsweetened cocoa powder
  • 12 tbsp unsalted butter melted, 1 1/2 sticks
  • 1 cup granulated sugar
  • ½ cup brown sugar packed
  • 2 large eggs room temperature
  • 1 tsp pure vanilla extract
  • ¾ tsp kosher salt
  • 1 cup semisweet chocolate chips for the ganache
  • ½ cup heavy cream
  • ¼ cup rainbow candy coated chocolate pieces for topping

Instructions
 

Cooking

  • Prep the pan. Heat the oven to 325 degrees F, spray a 9x9 inch pan, and line it with parchment.
  • Mix the dry ingredients. Whisk the flour and cocoa together in a bowl.
  • Make the batter. Whisk the melted butter and both sugars, then mix in the eggs, vanilla, and salt. Fold in the dry ingredients until just combined.
  • Bake. Spread the batter in the pan and bake 30 to 35 minutes, until a toothpick comes out nearly clean. Cool for 1 hour.
  • Make the ganache. Heat the cream until steaming, pour it over the chips, rest 2 minutes, and stir smooth. Spread it over the cooled brownies.
  • Top and chill. Scatter the rainbow pieces over the ganache and chill for 30 minutes before cutting.

Notes

Substitutions: Use mini candy coated chocolates or rainbow sprinkles for the topping, and milk or dark chips for the ganache.
Tips: Cool the brownies fully before adding the ganache. Do not taste the raw batter because it contains raw eggs.
Storage: Refrigerate for up to 4 days or freeze for up to 3 months.
