Ingredients
For the brownies
- 10 tablespoons unsalted butter
- 1 cup granulated sugar
- 1/3 cup packed light brown sugar
- 3/4 cup plus 2 tablespoons unsweetened cocoa powder, sifted
- 1/2 teaspoon vanilla extract
- 2 large eggs plus 1 egg yolk
- 1 tablespoon corn syrup
- 2/3 cup all-purpose flour

For the frosting
- 1/2 cup heavy cream
- 1 1/2 cups semisweet chocolate chips

Step-by-Step: How to Make Cosmic Brownies recipe
Step 1: Prepare the pan
Preheat your oven to 350°F. Line an 8-by-8-inch baking pan with parchment paper or foil. Lightly spray it with cooking spray to prevent sticking.
Step 2: Melt and mix
In a microwave-safe bowl, melt the butter for about 90 seconds. Stir in granulated sugar, brown sugar, and cocoa powder until smooth. Let the mixture cool slightly if it feels too hot.
Step 3: Add wet ingredients
Mix in the vanilla extract, eggs, egg yolk, and corn syrup. Stir until the batter becomes glossy and well combined.
Step 4: Add dry ingredients
Add flour, cornstarch, and salt. Stir gently until just combined. Do not overmix, as this can affect the texture.
Step 5: Bake
Spread the thick batter evenly into your prepared pan. Bake for about 25 minutes. The center should be set but still soft. Let the brownies cool completely in the pan.
Step 6: Make the frosting
Heat the heavy cream in the microwave for about 1 minute. Add chocolate chips and let sit for 3 minutes. Stir until smooth and glossy.
Step 7: Assemble
Pour the frosting over cooled brownies and spread evenly. Sprinkle candy-coated chocolate chips on top.
Step 8: Chill and slice
Refrigerate for 1 to 2 hours until the frosting sets. Cut into squares and serve chilled for the best texture.
Helpful Tips
- Use high-quality cocoa powder for richer flavor
- Do not overbake or brownies will lose their fudgy texture
- Let brownies cool completely before frosting to avoid melting
