- ½ cup unsalted butter
- ¾ cup granulated sugar
- ¼ cup brown sugar
- ½ cup Dutch-process cocoa powder
- ¼ tsp salt
- 1 tsp vanilla extract
- 2 large eggs (room temperature)
- ½ cup all-purpose flour
- 1 tbsp cornstarch
- ¼ cup heavy cream
- 4 oz semisweet chocolate (chopped)
- Pinch of salt
- 2–3 tbsp rainbow candy-coated chocolate chips (Wilton rainbow chips or similar)
How to Make Gourmet Cosmic Brownies Recipe
Preheat and Prepare: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal later.
Make the Brownie Batter: In a large mixing bowl, melt the unsalted butter in the microwave or over a double boiler. Whisk in the granulated sugar and brown sugar until well combined. Stir in the cocoa powder, salt, and vanilla extract. Allow the mixture to cool for a few minutes.
Incorporate the Eggs: Once the mixture has cooled slightly, add the room temperature eggs one at a time, mixing until smooth and glossy after each addition.
Add Dry Ingredients: Gently fold in the all-purpose flour and cornstarch, mixing just until no dry bits remain. Be careful not to overmix; the batter should look thick and luscious.
Bake the Brownies: Pour the brownie batter into the prepared pan, smoothing the top with a spatula. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Make the Ganache: While the brownies are baking, heat the heavy cream in a small saucepan over medium heat until simmering. Remove from heat and immediately pour over the chopped semisweet chocolate in a separate bowl. Let it sit for a minute, then whisk until smooth and glossy.
Add Rainbow Chips and Chill: Once the brownies have cooled for about 10 minutes, pour the ganache over them, spreading it evenly. Sprinkle the rainbow candy-coated chocolate chips on top. Refrigerate for at least 1 hour to allow the ganache to set.
Tips for Best Results
- Ensure the butter is melted but not hot when mixing with sugar; otherwise, it could cook the eggs.
- Use a rubber spatula to fold in the flour mixture gently so that the brownies remain tender.
- Keep an eye on the baking time since ovens can vary; avoid overbaking for the best texture.
- For clean cuts, use a sharp knife and wipe it clean between slices.
Variations and Substitutions
If you want to experiment, consider adding chopped nuts or swapping the rainbow chips for different kinds of chocolate chips. You could also try adding a hint of espresso powder to amplify the chocolaty depth. Just remember that major substitutions may alter the final texture.
How to Serve It

Serve these gourmet brownies in squares or rectangles, perhaps with a scoop of vanilla ice cream on the side for an indulgent dessert experience. They pair beautifully with a drizzle of chocolate sauce or a sprinkle of powdered sugar for added flair.
How to Store It
To keep your brownies fresh, store them in an airtight container at room temperature for up to 3 days. For longer storage, they can be refrigerated for up to a week, or frozen for about 2 months. If you freeze them, slice them once they are fully chilled and wrap each piece individually. Wait to add any toppings until just before serving for optimal presentation.
