Ingredients for Easy Cosmic Brownies
This recipe keeps things simple while delivering maximum flavor.
For the brownies:
1 cup unsalted butter (melted)
1 cup granulated sugar
1 cup brown sugar
3 large eggs
1 tablespoon vanilla extract
1 cup all-purpose flour
¾ cup cocoa powder
½ teaspoon salt
For the chocolate topping:
1 cup semi-sweet chocolate chips
½ cup heavy cream
For topping:
Colorful candy-coated chocolate chips (cosmic style)
Sprinkles (optional)
Step by Step Easy Cosmic Brownie Recipe
Follow these steps carefully for that perfect fudgy texture.
Step 1: Prepare the Batter
In a large 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.
Step 2: Mix Dry Ingredients
In another bowl, combine flour, cocoa powder, and salt. Gradually add this mixture into the wet ingredients.
Mix until just combined. Do not overmix, as this can make brownies dense in a bad way.
Step 3: Bake the Brownies
Pour the batter into a lined baking pan and spread evenly.
Bake at 350°F (175°C) for 20 to 25 minutes. The center should be set but still slightly soft for that fudgy texture.
Let the brownies cool completely before adding topping.
Preparing the Chocolate Ganache
Step 4: Make the Ganache
Heat heavy cream until warm but not boiling. Pour it over chocolate chips and let sit for 1 to 2 minutes.
Stir until smooth and glossy. This creates that signature cosmic brownie topping.
Assembling the Cosmic Brownies
Step 5: Add Chocolate Layer
Spread the ganache evenly over the cooled brownies.
Step 6: Add Toppings
Immediately sprinkle colorful candy-coated chocolates on top before the ganache sets.
Let everything sit until the topping firms up.
Step 7: Slice and Serve
Cut into square pieces and enjoy that classic cosmic brownie look.
