Gourmet Cosmic Brownies Bars (Printable)
Rich brownie bars with silky ganache and rainbow candy topping, chilled for a glossy, indulgent finish.
# 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 the oven to 350°F. Line an 8×8-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth and glossy.
03 - Add the eggs and vanilla extract, whisking until well combined and the mixture appears slightly lightened in color.
04 - Sift the cocoa powder, flour, and salt directly into the wet mixture. Gently fold with a spatula until just combined — avoid overmixing to keep the texture tender.
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 - Let the brownie base cool completely in the pan set on a wire rack.
07 - Place the chopped chocolate and butter in a heatproof bowl. Heat the heavy cream in a small saucepan until just steaming — do not boil — then pour it over the chocolate. Let sit for 2 minutes.
08 - Stir the ganache gently until smooth and glossy. Spread it evenly over the cooled brownie base using an offset spatula.
09 - Sprinkle the candy-coated chocolate chips evenly over the ganache. 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 chilled or at room temperature.
# Expert Tips:
01 -
- The brownie base hits that impossible sweet spot between dense fudge and tender cake, something store bought could never replicate.
- That glossy ganache topping sets into a shell that cracks beautifully when you bite into it, and the rainbow candies on top make everyone smile before they even taste it.
02 -
- Underbaking slightly is the single most important thing you can do because the brownies continue cooking in the pan as they cool and nobody wants a dry edge.
- Ganache can seize if even a single drop of water gets into the bowl, so make sure every utensil and surface is completely dry before you start.
03 -
- Run your knife under hot water and dry it between each cut for bakery perfect edges that make people think you spent hours on presentation.
- Let the ganache sit on the brownie for five minutes before adding the candies so they stick without sinking completely into the chocolate.
