How to Make Gourmet Cosmic Brownies Recipe
Step 1: Prepare Your Oven and Baking Pan
Preheat your oven to 350°F (175°C). Grease your 9×9 inch baking pan or line it with parchment paper for easy removal later.
Step 2: Melt Butter and Mix Sugars
In a saucepan over low heat, melt the unsalted butter. Once melted, remove from heat and whisk in granulated sugar and brown sugar until combined.
Step 3: Add Cocoa Powder and Eggs
Stir in Dutch-process cocoa powder and salt into the butter-sugar mixture. Allow it to cool slightly before adding eggs one at a time, whisking well after each addition. Then stir in vanilla extract.
Step 4: Combine Dry Ingredients
In a separate bowl, mix together all-purpose flour and cornstarch. Gradually fold this mixture into your wet ingredients until just combined. Do not overmix!
Step 5: Bake the Brownies
Pour the brownie batter into your prepared baking pan. Bake for about 20 minutes or until a toothpick inserted comes out with moist crumbs.
Step 6: Prepare Ganache Topping
While brownies cool, heat heavy cream in a small saucepan until simmering. Remove from heat and add chopped semisweet chocolate. Let it sit for a minute before stirring until smooth.
Step 7: Assemble Your Brownies
Spread the ganache evenly over cooled brownies. Sprinkle with rainbow candy-coated chocolate chips while the ganache is still warm.
Step 8: Cut and Serve
Once set, cut into squares and enjoy! These delectable bites are sure to please everyone!

Common Mistakes to Avoid
Making Gourmet Cosmic Brownies Recipe can be fun, but there are some common mistakes you should avoid to ensure the best results.
- Using cold ingredients – Always use room temperature eggs and butter. Cold ingredients can lead to uneven baking.
- Overmixing the batter – Mix just until combined. Overmixing can create tough brownies instead of fudgy ones.
- Not measuring accurately – Use a kitchen scale or measuring cups for precision. Incorrect measurements can alter the texture and taste.
- Skipping the cooling time – Allow brownies to cool completely before cutting. This helps them set and maintain their shape.
