Gourmet Cosmic Brownies Recipe
Introduction
These Gourmet Cosmic Brownies are rich, fudgy, and topped with a glossy chocolate ganache and colorful rainbow candy chips. Perfect for a special treat, they combine classic brownie flavors with a fun, cosmic twist.

Ingredients
- 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)
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line an 8×8 inch pan with parchment paper.
- Step 2: In a medium saucepan, melt the butter over low heat. Once melted, stir in the granulated sugar, brown sugar, cocoa powder, and ¼ teaspoon salt until smooth and well combined.
- Step 3: Transfer the mixture to a large bowl. Whisk in the vanilla extract, then add the eggs one at a time, beating well after each addition until the batter is thick and shiny.
- Step 4: Gently fold in the all-purpose flour and cornstarch just until combined—do not overmix.
- Step 5: Spread the batter evenly into the prepared pan. Bake for 20-22 minutes, until the edges are set and the center jiggles slightly when shaken.
- Step 6: Allow the brownies to cool completely in the pan. Then flip them out and peel away the parchment paper for a smooth surface.
- Step 7: To make the ganache, heat the heavy cream in the microwave for about 30 seconds until hot but not boiling. Pour it over the chopped semisweet chocolate, add a pinch of salt, and let sit for 1 minute. Stir until the mixture is smooth and glossy.
- Step 8: Spread the ganache evenly over the cooled brownies.
- Step 9: While the ganache is still soft, sprinkle the rainbow candy-coated chocolate chips on top.
- Step 10: Chill the brownies for 1 to 2 hours until the ganache sets. For clean slices, wipe your knife between cuts.
Tips & Variations
- Use high-quality Dutch-process cocoa for a richer chocolate flavor.
- Let the eggs come to room temperature before mixing to ensure a smoother batter.
- Try swapping rainbow chips for chopped nuts or sea salt flakes for a different texture twist.
- For extra fudginess, slightly underbake the brownies by a couple of minutes.
Storage
Store the brownies in an airtight container in the refrigerator for up to 4 days. Bring them to room temperature before serving for the best texture. You can also freeze the brownies for up to 2 months; thaw overnight in the fridge before enjoying.

FAQs
Can I use regular cocoa powder instead of Dutch-process?
Yes, but the flavor and color might be slightly different. Dutch-process cocoa tends to be smoother and less acidic.
What if I don’t have cornstarch?
You can omit the cornstarch, but it helps create a tender, cakey texture. If you don’t have any, substitute with an equal amount of flour.

Instructions
- Make the Brownies: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper for easy removal.

- Clean your knife between slices for neat presentation, especially with ganache topping.
- Rainbow candy chips can be substituted with any colorful candy-coated chocolates for customization.
