Ingredients

Scale

Brownie Base

  • ½ cup unsalted butter
  • ¾ cup granulated sugar
  • ¼ cup brown sugar
  • ½ cup Dutch-process cocoa powder
  • ¼ tsp salt
  • 1 tsp vanilla extract
  • 2 large eggs (room temperature)
  • ½ cup all-purpose flour
  • 1 tbsp cornstarch

Chocolate Ganache

  • ¼ cup heavy cream
  • 4 oz semisweet chocolate (chopped)
  • Pinch of salt

Topping

  • 23 tbsp rainbow candy-coated chocolate chips (Wilton rainbow chips or similar)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to ensure easy removal of the brownies later.
  2. Make Brownie Batter: In a medium saucepan over the stove, melt the unsalted butter. Once melted, stir in the granulated sugar, brown sugar, Dutch-process cocoa powder, and ¼ teaspoon of salt until the mixture is smooth and well blended.
  3. Incorporate Vanilla and Eggs: Transfer the butter and cocoa mixture to a large bowl. Whisk in the vanilla extract, then add the eggs one at a time, beating well after each addition until the batter becomes thick and shiny.
  4. Add Dry Ingredients: Gently fold in the all-purpose flour and cornstarch until just combined, being careful not to overmix the batter.
  5. Bake the Brownies: Spread the batter evenly into the prepared pan. Bake for 20-22 minutes, or until the edges are set but the center still has a slight jiggle. Remove from the oven and allow to cool completely in the pan.
  6. Prepare the Ganache: Once the brownies are cooled, microwave the heavy cream for about 30 seconds until hot but not boiling. Pour the hot cream over the chopped semisweet chocolate and let sit for 1 minute. Add a pinch of salt and stir until the ganache is smooth and glossy.
  7. Apply Ganache: Flip the cooled brownies out of the pan to remove the parchment paper, achieving a smooth flat surface. Spread the prepared ganache evenly over the top of the brownies.
  8. Add Rainbow Topping: While the ganache is still soft, sprinkle 2–3 tablespoons of rainbow candy-coated chocolate chips on top to create a colorful cosmic effect.
  9. Chill and Set: Place the brownies in the refrigerator and chill for 1 to 2 hours until the ganache is set and firm.
  10. Slice and Serve: Before slicing, wipe your knife clean between cuts for neat brownie slices. Serve and enjoy these indulgent cosmic brownies!

Notes

  • Room temperature eggs help the batter to emulsify better, resulting in a smoother texture.
  • Do not overbake the brownies; the center should still have a slight jiggle when done to maintain fudginess.
  • For a cleaner look, flipping the brownies before adding ganache creates a flat surface for the topping.
  • Use high-quality Dutch-process cocoa powder for a rich chocolate flavor.
  • Store chilled brownies covered in an airtight container for up to 4 days.
