Ingredients
The Brownies:
1 cup unsalted butter, melted
1 cup granulated sugar
½ cup brown sugar, packed
3 large eggs
1 tsp vanilla extract
¾ cup cocoa powder (unsweetened)
1 cup all-purpose flour
½ tsp salt
The Ganache Topping:
1 cup semisweet chocolate chips
½ cup heavy cream
The Toppings:
½ cup rainbow candy-coated chocolate chips (or mini M&Ms)
Instructions
Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving an overhang for easy removal.
Make the Brownie Batter: In a large mixing bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract. In a separate bowl, sift together cocoa powder, flour, and salt. Gradually fold the dry ingredients into the wet mixture until combined, being careful not to overmix.
Bake the Brownies: Pour the batter into the prepared pan and level the top with a spatula. Bake for 25 minutes, or until a toothpick inserted in the center comes out with moist crumbs but no wet batter. Allow the brownies to cool completely in the pan before adding the ganache.
Make the Ganache: Heat the heavy cream in a microwave-safe bowl or small saucepan until it begins to simmer, making sure it does not boil. Pour the hot cream over the semisweet chocolate chips and let sit for 2–3 minutes. Stir gently until the ganache is smooth and glossy.
Assemble the Cosmic Brownies: Pour the ganache over the cooled brownies and spread evenly with a spatula. Sprinkle the rainbow candy-coated chocolate chips generously over the ganache.
Chill and Slice: Refrigerate the brownies for at least 1 hour to allow the ganache to set. Use the parchment paper overhang to lift the brownies out of the pan, then slice into squares or rectangles to replicate the classic Cosmic Brownie shape.
Notes
Be careful not to overmix the brownie batter to keep it fudgy and tender.
Use parchment paper with an overhang for easy removal of the brownies from the pan.
Allow the brownies to cool completely before adding ganache to prevent it from melting and running.
Chilling the brownies helps the ganache set firmly for clean slicing.
Substitute heavy cream with coconut cream for a dairy-free ganache alternative.
Store the brownies refrigerated and bring to room temperature before serving for the best texture.
