Gourmet Cosmic Brownies Bars (Printable)
Fudgy chocolate bars with glossy ganache and rainbow sprinkles — nostalgic, rich, and perfect for slicing.
# What You Need:
→ Brownie Base
01 - 3/4 cup (1.5 sticks) unsalted butter, melted
02 - 1 cup granulated sugar
03 - 2/3 cup light brown sugar, packed
04 - 2 large eggs
05 - 1 large egg yolk
06 - 2 tsp pure vanilla extract
07 - 2/3 cup unsweetened cocoa powder
08 - 1 cup all-purpose flour
09 - 1/4 tsp salt
→ Chocolate Ganache
10 - 6 oz semi-sweet chocolate, finely chopped
11 - 1/2 cup heavy cream
12 - 1 tbsp unsalted butter
→ Topping
13 - 1/3 cup candy-coated chocolate chips or rainbow sprinkles
# Directions:
01 - Preheat oven to 350°F. Line an 8x8 inch 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 well blended.
03 - Add the eggs, egg yolk, and vanilla extract to the sugar mixture. Whisk vigorously until the batter becomes light, glossy, and slightly thickened.
04 - Sift the cocoa powder, flour, and salt directly into the wet mixture. Fold gently with a spatula until just combined — avoid overmixing to keep the brownies tender.
05 - Pour the batter into the prepared pan and spread it into an even layer. Bake for 22–25 minutes, or until the center is just set but still slightly soft. Do not overbake.
06 - Transfer the pan to a wire rack and let the brownies cool completely in the pan before adding the topping.
07 - Place the finely chopped chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream until it just begins to simmer, then pour it over the chocolate. Let sit for 2 minutes, add the butter, then stir gently until the ganache is smooth and glossy.
08 - Spread the ganache evenly over the cooled brownie surface. Immediately scatter the candy-coated chocolate chips or rainbow sprinkles on top, pressing gently so they adhere to the ganache.
09 - Refrigerate the brownies for at least 20 minutes to allow the ganache to set firmly. Use the parchment overhang to lift the brownies out of the pan, then slice into 12 even bars and serve.
# Expert Suggestions:
01 -
- The ganache sets into a shiny mirror like top that crackles slightly when you cut through it.
- They taste like the ones you remember but denser, darker, and completely unapologetic about it.
02 -
- If you overbake these by even three minutes the center goes from fudgy to dry and no amount of ganache can hide it.
- The ganache must cool on the brownies at room temperature before refrigerating, a sudden temperature shift can cause condensation and a dull surface.
03 -
- Run your knife under hot water and wipe it dry between each cut for perfectly clean bakery style slices.
- Adding sixty grams of mini chocolate chips to the batter before baking creates little pockets of melted chocolate inside that make each bite more interesting.
