Gourmet Cosmic Brownies Recipe
Introduction
These Gourmet Cosmic Brownies combine rich chocolate with a fun, colorful twist. With a smooth chocolate ganache topped with rainbow candy chips, they’re perfect for a special treat or celebration.

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 the oven to 350°F. Line an 8×8-inch pan with parchment paper.
- Step 2: Melt the butter in a medium saucepan over the stove. Stir in granulated sugar, brown sugar, cocoa powder, and ¼ tsp salt until the mixture is smooth and well blended.
- Step 3: Transfer the mixture to a large bowl. Whisk in the vanilla extract, then add the eggs one at a time, beating well until the batter becomes thick and shiny.
- Step 4: Fold in the flour and cornstarch gently until just combined.
- Step 5: Spread the batter evenly into the prepared pan and bake for 20-22 minutes, until the edges are set and the center has a slight jiggle. Let the brownies cool completely in the pan.
- Step 6: Once cool, invert the brownies onto a flat surface and carefully remove the parchment paper for an even surface.
- Step 7: To make the ganache, heat the heavy cream in the microwave for 30 seconds. Pour it over the chopped semisweet chocolate and let sit for 1 minute. Add a pinch of salt and stir until smooth.
- Step 8: Spread the ganache evenly over the cooled brownies.
- Step 9: Sprinkle the rainbow candy-coated chocolate chips over the ganache while it is still soft.
- Step 10: Chill the brownies in the refrigerator for 1-2 hours before slicing. For clean edges, wipe the knife between each cut.
Tips & Variations
- For extra fudgy brownies, avoid overbaking and remove when the center still jiggles slightly.
- Use your favorite candy-coated chocolates if you can’t find Wilton rainbow chips.
- Room temperature eggs help the batter mix more smoothly and create a better texture.
- For a nutty twist, sprinkle chopped walnuts or pecans on the ganache before chilling.
Storage
Store these brownies in an airtight container in the refrigerator for up to 4 days. Bring to room temperature before serving for best flavor and texture. Leftovers can also be frozen for up to 2 months; thaw in the refrigerator overnight before enjoying.

FAQs
Can I use regular cocoa powder instead of Dutch-process?
Yes, but Dutch-process cocoa is less acidic and provides a deeper chocolate flavor. Using regular cocoa may slightly change the taste and texture but will still yield tasty brownies.
How do I know when the brownies are done baking?
The edges should look set and start to pull away from the pan, while the center should still have a slight jiggle when you gently shake the pan. Avoid baking until fully firm to keep them fudgy.

Perfectly balanced with a hint of salt and vanilla, these brownies offer a decadent dessert experience that is both visually stunning and irresistibly delicious.
Ingredients
Brownie Base
- 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
Ganache
- ¼ cup heavy cream
- 4 oz semisweet chocolate, chopped
- Pinch of salt
Topping
- 2–3 tbsp rainbow candy-coated chocolate chips (Wilton rainbow chips or similar)
Instructions
- Make the Brownie Base: Preheat your oven to 350°F (177°C) and line an 8×8-inch baking pan with parchment paper. In a medium saucepan over low heat, melt the unsalted butter. Once melted, add granulated sugar, brown sugar, Dutch-process cocoa powder, and salt. Stir continuously until the mixture is smooth and well combined. Transfer this mixture to a large bowl and whisk in the vanilla extract. Add the eggs one at a time, beating well after each addition until the batter is thick and shiny. Gently fold in the all-purpose flour and cornstarch until just incorporated, being careful not to overmix.
- Bake the Brownies: Pour the batter evenly into the prepared pan and spread it out smoothly. Bake for 20-22 minutes until the edges are set and the center has a slight jiggle. Remove from oven and allow to cool completely in the pan.
- Prepare for Ganache: Once cool, carefully flip the brownies onto a flat surface and peel off the parchment paper to reveal an even, flat surface. This step ensures a clean base for the ganache layer.
- Make the Ganache: Heat the heavy cream in the microwave for about 30 seconds until hot but not boiling. Pour the hot cream over the chopped semisweet chocolate and let it sit for 1 minute to soften. Add a pinch of salt and stir the mixture until smooth and glossy.
- Assemble the Topping: Spread the ganache evenly over the surface of the brownies while it is still soft. Immediately sprinkle 2-3 tablespoons of rainbow candy-coated chocolate chips on top to create a colorful cosmic effect.
- Chill and Serve: Place the brownies in the refrigerator and chill for 1-2 hours to set the ganache completely. When ready to serve, use a sharp knife wiped clean between cuts to slice the brownies neatly and enjoy!
Notes
- Use room temperature eggs for better batter consistency and texture.
- Do not overbake the brownies; the center should remain slightly jiggly for a fudgy texture.
- For best results, use Dutch-process cocoa powder for a richer flavor.
- If you prefer a dairy-free version, substitute vegan butter, non-dairy cream, and dark dairy-free chocolate in the ganache.
- To keep the rainbow chips colorful and intact, sprinkle them only after spreading the ganache and chill immediately.
- Store brownies chilled in an airtight container for up to 5 days.
