Cosmic Brownies
Description
Cosmic Brownies start by mixing melted butter with granulated and brown sugars, cocoa powder, vanilla, eggs, and corn syrup, then folding in flour, cornstarch, and salt to create a thick batter. Baking at 350°F for 25 minutes yields a fudgy but set brownie with a tender crumb. After cooling, a ganache made by combining warmed heavy cream with semisweet chocolate chips is poured over the brownies and smoothed evenly. Bright candy-coated chocolate chips or mini M&Ms scatter atop the frosting for added sweetness and a colorful presentation.
The brownies are best served after chilling the frosting for 1 to 2 hours to set, ensuring clean slices. They can be stored airtight and enjoyed over several days. This recipe allows substituting candy toppings based on availability and preference.
Ingredients
For the brownies:
- 10 tablespoons unsalted butter 142 grams
- 1 cup granulated sugar 200 grams
- 1/3 cup light brown sugar packed, 67 grams
- 3/4 cup unsweetened cocoa powder sifted
- 1/2 teaspoon vanilla extract
- 2 egg large eggs plus 1 yolk
- 1 tablespoon corn syrup
- 2/3 cup all-purpose flour
- 1 tablespoon cornstarch
- 1/4 teaspoon salt
For the frosting:
- 1/2 cup heavy cream
- 1 1/2 cups semisweet chocolate chips 255 grams
- candy-coated chocolate chips or mini M&M’s, sprinkles, or other candy, for topping, rainbow
Instructions
Make the brownies:
- Preheat the oven to 350°F. Line an 8-by-8-inch metal baking pan with parchment or foil and spray with cooking spray.
- In a large microwave-safe bowl, melt the butter for about 90 seconds on high power. Stir in the granulated sugar, brown sugar, and cocoa powder. If still very hot, let cool slightly before adding in the vanilla, eggs, egg yolk, and corn syrup. Stir until very well combined. Add in the flour, cornstarch, and salt and stir until just combined. Batter will be thick. Pour into the prepared pan and bake for 25 minutes. Let cool completely in the pan.
Make the frosting:
- Place the cream in a small microwave-safe bowl and microwave on high for 1 minute. Add in the chocolate chips. Let stand for 3 minutes before stirring until smooth. Pour over the cooled brownies and smooth evenly. Sprinkle with the Rainbow Candy-Coated Chocolate Chips. Refrigerate for 1 to 2 hours, or until the frosting is set, before cutting.
- Brownies can be stored in an airtight container for 3 days at room temperature and for 1 week in the fridge. Brownies are best served chilled.
Notes
- If Wilton Rainbow Crunch candy chips are unavailable, use rainbow sprinkles, mini M&Ms, or preferred colorful candy-coated chocolates as toppings.
- Refrigerate brownies to allow frosting to firm before cutting and serving for best texture.
