Gourmet Cosmic Brownies Recipe
Introduction
Gourmet Cosmic Brownies are a rich, fudgy treat topped with a smooth chocolate ganache and vibrant rainbow candy chips. Perfect for special occasions or when you crave a decadent chocolate dessert with a fun 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 and line an 8×8 inch pan with parchment paper.
- Step 2: In a medium saucepan, melt the butter over low heat. Remove from heat and 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 until just combined—do not overmix.
- Step 5: Spread the batter evenly into the prepared pan and bake for 20–22 minutes, or until the edges are set but the center still has a slight jiggle. Allow to cool completely.
- Step 6: Once cool, flip the brownies out of the pan and remove the parchment paper. This gives the surface a flat, clean finish for the ganache.
- 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 one minute. Add a pinch of salt, then stir until smooth.
- Step 8: Spread the ganache evenly over the cooled brownies.
- Step 9: Immediately sprinkle the rainbow candy-coated chocolate chips over the soft ganache.
- Step 10: Chill the brownies for 1–2 hours before slicing. For clean cuts, wipe the knife between each slice.
Tips & Variations
- Use room temperature eggs for a smoother batter and better rise.
- Try substituting the rainbow chips with chopped nuts or dried fruit for a different texture.
- Ensure the ganache is warm but not hot when spreading to avoid melting the candy chips.
Storage
Store the brownies in an airtight container in the refrigerator for up to 5 days. Let them come to room temperature before serving for the best texture. You can also freeze the brownies (without the candy chips) for up to 2 months, thawing overnight in the fridge.

FAQs
Can I use regular cocoa powder instead of Dutch-process?
Yes, but the flavor and color will be slightly different. Dutch-process cocoa provides a smoother, less acidic taste.
What if I don’t have cornstarch?
You can omit the cornstarch or substitute it with an equal amount of additional flour. Cornstarch helps keep the brownies tender and fudgy.

Ingredients
Brownie Batter
- 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 (such as Wilton rainbow chips or similar)
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.
- Prepare the batter: In a medium saucepan, melt the unsalted butter over medium heat. Once melted, stir in granulated sugar, brown sugar, Dutch-process cocoa powder, and salt. Mix until smooth and fully blended.
- Incorporate eggs and vanilla: Transfer the chocolate mixture to a large bowl. Whisk in the vanilla extract. Add the eggs one at a time, beating well after each addition until the batter is thick and shiny.
- Add dry ingredients: Gently fold in the all-purpose flour and cornstarch until just combined, taking care not to overmix.
- Bake the brownies: Spread the batter evenly into the prepared pan. Bake for 20-22 minutes, or until the edges are set but the center still has a slight jiggle. Remove from the oven and allow to cool completely in the pan.
- Remove brownies from pan: Once cool, flip the brownies out onto a flat surface and peel off the parchment paper. This ensures a flat surface for the ganache.
- Make ganache: Heat the heavy cream in the microwave for about 30 seconds or until just simmering. Pour the hot cream over the chopped semisweet chocolate and let it sit for 1 minute. Add a pinch of salt and stir gently until smooth and glossy.
- Apply ganache: Spread the smooth ganache evenly over the cooled brownie layer to cover the entire surface.
- Add toppings and chill: Immediately sprinkle 2–3 tablespoons of rainbow candy-coated chocolate chips over the soft ganache. Transfer the brownies to the refrigerator and chill for 1-2 hours until the ganache is set.
- Slice and serve: For clean edges, wipe your knife between cuts as you slice the brownies into desired portions. Serve and enjoy your colorful, decadent cosmic brownies.
Notes
- For the best texture, use room temperature eggs to ensure smooth incorporation into the batter.

- You can substitute semisweet chocolate with dark chocolate in the ganache for a richer flavor.
- Store the brownies chilled in an airtight container for up to 4 days.
- Let the brownies come to room temperature before serving for the best flavor and texture.
