Cosmic brownies

  • 1⅔ cup all-purpose flour
  • 6 tbsp unsalted butter melted
  • 1 cup granulated sugar
  • 2 large eggs
  • ½ cup unsweetened cocoa powder
  • ½ tsp salt
  • 2 tbsp 2% milk
  • 2 tsp vanilla extract

Fudge like frosting

  • 4 oz milk chocolate chopped
  • 4 oz semi sweet chocolate
  • cup heavy cream
  • 1 tbsp unsalted butter chopped
  • 1.4 oz rainbow confetti sprinkles


For the brownies

  • Preheat oven to 350°. Spray a 9x9 baking pan with non stick spray and then line with parchment paper, leaving overhang on the sides. Set aside.
  • Microwave the unsalted butter in 30 second increments until completely melted.
  • In a large mixing bowl, transfer melted butter and add sugar and whisk until just combined. With electric mixer, beat on medium for 2-3 minutes until mixture light and fluffy.
  • Add the eggs and vanilla extract and beat for an additional 2 minutes until mixture is thick and pale.
  • Add the flour, cocoa powder, and salt. Mix on low until the ingredients have just combined. Stir the milk in until it is smooth.
  • Transfer batter to prepared pan and spread evenly. Bake for 20 minutes or until toothpick inserted into the center comes out clean or with just a few crumbs. Let the brownies cool.

For the frosting

  • In a medium saucepan, heat heavy cream until it just simmers. Add in the chopped chocolate and let it sit for about 3-5 minutes. Stir until smooth and then add the butter and mix until melted.
  • Pour the chocolate over the brownies and use a spatula to spread the chocolate into an even layer. Add the rainbow sprinkles on top.
  • Chill the brownies for about 1-2 hours. Lift brownies out of the pan cut cut into squares. Serve and enjoy!
