How to Make Gourmet Cosmic Brownies Recipe
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your brownies bake evenly.
Step 2: Prepare the Baking Pan
Grease a 9×9-inch baking pan with butter or line it with parchment paper. This prevents sticking and makes for easy removal.
Step 3: Make the Brownie Batter
- In a mixing bowl, melt the unsalted butter.
- Add both sugars and whisk until well combined.
- Stir in cocoa powder, salt, and vanilla extract.
- Beat in the eggs one at a time until fully incorporated.
- Gently fold in all-purpose flour and cornstarch until just combined.
Step 4: Bake the Brownies
Pour the brownie batter into the prepared pan. Smooth out the top with a spatula.
Bake in preheated oven for about 20 minutes or until a toothpick inserted comes out with moist crumbs.
Step 5: Prepare the Ganache
- In a double boiler or microwave-safe bowl, heat heavy cream until hot but not boiling.
- Add chopped semisweet chocolate and let it sit for about 2 minutes before stirring until smooth.
Step 6: Top with Ganache and Sprinkles
Once brownies have cooled slightly, pour ganache over them while still warm. Use a spatula to spread it evenly across the surface.
Sprinkle rainbow candy-coated chocolate chips on top before ganache sets.
Step 7: Cool and Serve
Allow brownies to cool completely before cutting into squares. Enjoy your delicious Gourmet Cosmic Brownies!

How to Perfect Gourmet Cosmic Brownies Recipe
Making these gourmet cosmic brownies is simple, but a few tips can help you achieve perfection. Follow these guidelines for the best results.
Use room temperature eggs: This helps them mix more evenly into the batter, resulting in a smoother texture.
Sift cocoa powder: Sifting removes lumps and ensures an even distribution of cocoa throughout the batter, enhancing flavor.
Don’t overmix: Stir just until ingredients are combined to maintain the fudgy texture of your brownies.
Check doneness carefully: Insert a toothpick into the center; it should come out with moist crumbs, not completely clean, for that perfect fudgy bite.
Cool before cutting: Allowing brownies to cool completely ensures cleaner cuts and prevents them from falling apart when served.
Store properly: Keep leftovers in an airtight container at room temperature or refrigerate to maintain freshness.
Best Side Dishes for Gourmet Cosmic Brownies Recipe
These gourmet cosmic brownies pair wonderfully with various side dishes that enhance their flavor profile. Consider these delicious options:
- Vanilla Ice Cream – A classic pairing that adds creaminess and balances out the rich chocolate flavor.
- Whipped Cream – Lighten up each bite with fluffy whipped cream, providing a delightful contrast to the dense brownies.
- Fruit Salad – A refreshing mix of seasonal fruits can brighten up your dessert table and add a healthy touch.
- Chocolate Sauce – Drizzle warm chocolate sauce over the top for an extra indulgent treat that chocolate lovers will adore.
- Nut Medley – Serve a small dish of mixed nuts for crunch and saltiness, complementing the sweetness of the brownies perfectly.
- Coffee or Espresso – A strong cup of coffee enhances chocolate flavors, making it an ideal drink pairing with your brownies.

Common Mistakes to Avoid

- Skipping Room Temperature Ingredients: Using cold eggs or butter can lead to an uneven batter. Always ensure your eggs and butter are at room temperature for best results.

- Not Measuring Ingredients Accurately: Baking is a science, and incorrect measurements can ruin your brownies. Use measuring cups and spoons for precision.
- Ignoring Oven Temperature: Ovens can vary in temperature. Always preheat your oven to the correct temperature and consider using an oven thermometer for accuracy.
