Ingredients

Scale
For the Brownies
  • 1 cup (2 sticks) unsalted butter, melted
  • 1 cup granulated sugar
  • ¾ cup light brown sugar, packed
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • ½ teaspoon salt
  • ½ teaspoon baking powder
For the Ganache Topping
  • 1 cup heavy cream
  • 1 ½ cups semisweet chocolate chips
  • 1 teaspoon vanilla extract
For Decoration

  • ¼ cup rainbow candy-coated chocolate chips (like mini M&Ms)

Instructions

Make the Brownies
  1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper or grease it lightly.
  2. In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
  3. Add the eggs and vanilla extract, mixing until fully combined.
  4. In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder.
  5. Gradually fold the dry ingredients into the wet ingredients until just combined. Do not overmix.
  6. Pour the brownie batter into the prepared baking dish and smooth the top.
  7. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  8. Let the brownies cool completely before adding the ganache.
Make the Ganache
  1. In a small saucepan, heat the heavy cream over medium heat until it just starts to simmer. Do not boil.
  2. Remove from heat and pour over the chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir until smooth and glossy.
  3. Stir in the vanilla extract.
Assemble the Cosmic Brownies
  1. Pour the ganache evenly over the cooled brownies and smooth with a spatula.
  2. Immediately sprinkle the rainbow candy-coated chocolate chips over the top.
  3. Let the ganache set at room temperature for about 1 hour, or chill in the fridge for a faster set.
  4. Slice into squares and enjoy!
Storage

  • Store in an airtight container at room temperature for 3 days or in the fridge for up to 1 week.

Notes


  • For an even fudgier texture, slightly underbake the brownies and let them cool completely before adding the ganache.
  • You can swap semisweet chocolate for dark chocolate in the ganache for a richer flavor.
  • Use a hot knife to slice clean brownie squares.
