Gourmet Cosmic Brownies Bars (Printable Version)

Rich brownie bars topped with glossy chocolate ganache and rainbow candy coating, nostalgic, indulgent, and shareable.

# What You'll Need:

→ Brownie Base

01 - 6 oz unsalted butter, melted
02 - 1 cup granulated sugar
03 - ½ cup light brown sugar, packed
04 - 2 large eggs
05 - 1 tsp pure vanilla extract
06 - ⅔ cup unsweetened cocoa powder
07 - ⅔ cup all-purpose flour
08 - ½ tsp fine sea salt

→ Chocolate Ganache

09 - 4 oz semi-sweet chocolate, chopped
10 - ½ cup heavy cream
11 - 1 tbsp unsalted butter

→ Topping

12 - ⅓ cup rainbow candy-coated chocolate chips (or mini M&M's)

# How to Make It:

01 - Preheat oven to 350°F. Line an 8x8-inch square baking pan with parchment paper, leaving enough overhang on the sides for easy removal.
02 - In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until the mixture is smooth and glossy.
03 - Add the eggs and vanilla extract to the sugar mixture, whisking vigorously until fully combined and the batter appears slightly lightened in color.
04 - Sift the cocoa powder, flour, and salt directly into the batter. Gently fold with a spatula until just combined — be careful not to overmix.
05 - Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 23–25 minutes, until the edges are set but the center still looks slightly underbaked.
06 - Transfer the pan to a wire rack and allow the brownies to cool completely in the pan before adding the ganache.
07 - Place the chopped semi-sweet chocolate and butter in a heatproof bowl. Heat the heavy cream in a small saucepan until just steaming, then pour it over the chocolate. Let sit for 2 minutes.
08 - Stir the chocolate mixture gently until smooth and glossy. Spread the ganache evenly over the cooled brownie base using a spatula.
09 - Sprinkle the candy-coated chocolate chips evenly over the ganache layer. Refrigerate for at least 30 minutes, or until the ganache is fully set.
10 - Lift the brownie slab from the pan using the parchment overhang. Slice into 12 even bars with a sharp knife and serve at your preferred temperature.

# Expert Insights:

01 -
  • The ganache sets into a glossy, truffle-like layer that makes every bite feel like sneaking dessert before dinner.
  • These bars taste like a memory you did not know you needed, but somehow better than the original.
02 -
  • Overbaking is the enemy of fudgy brownies, so take them out when the center still looks slightly underdone because they keep cooking in the pan.
  • Letting the cream come to a full boil can scald it and make the ganache grainy, so stop at a gentle steam.
03 -
  • Weight your flour and cocoa instead of scooping, because packed cups have ruined more brownies than any other mistake I have made.
  • Dip your knife in hot water and wipe it dry between each cut for bakery perfect edges that make people think you bought them.
