For the 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

- ½ cup all-purpose flour

How to Make Gourmet Cosmic Brownies Recipe
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
Step 2: Prepare the Brownie Batter
In a mixing bowl, melt the unsalted butter. Once melted, add granulated sugar and brown sugar. Mix well until combined. Then stir in Dutch-process cocoa powder, salt, and vanilla extract.
Step 3: Incorporate Eggs
Add two large eggs one at a time, mixing well after each addition until fully incorporated.
Step 4: Combine Dry Ingredients
Sift together all-purpose flour and cornstarch before adding them to the wet mixture. Stir gently until just combined; avoid over-mixing.
Step 5: Bake the Brownies
Pour the brownie batter into the prepared baking pan. Bake in preheated oven for about 20 minutes or until a toothpick inserted comes out slightly moist.
Step 6: Prepare Ganache Topping
While brownies bake, heat heavy cream in a small saucepan until it begins to simmer. Pour over chopped semisweet chocolate in another bowl. Let sit for a few minutes before stirring until smooth.
Step 7: Assemble
Once brownies have cooled slightly, pour ganache evenly on top. Spread it out with a rubber spatula if needed. Sprinkle rainbow candy-coated chocolate chips on top while ganache is still soft.
Step 8: Cool and Serve
Allow brownies to cool completely before slicing into squares. Enjoy these decadent treats fresh or store them in an airtight container!
