Ingredients
Brownies
1cupgranulated sugar
6tablespoonsunsalted butter,softened
2eggs
1egg yolk
1teaspoonvanilla extract
½cupall-purpose flour
⅓cupcocoa powder
¼teaspoonsalt
2tablespoonsmilk
Frosting
⅓cupheavy cream
½cupsemi-sweet chocolate,chopped
½cupmilk chocolate,chopped
½teaspoonvanilla extract
1tablespoonbutter,cut into 4 pieces
¼cuprainbow chip sprinkles
Instructions
Preheat the oven to 350°F. Line a 9x9-inch square pan with a piece of parchment paper, leaving an overhang on both sides. Coat the pan with cooking spray.
Add the sugar and butter to a large mixing bowl and use a hand mixer to beat together until light and fluffy, about 1 minute.
Add the eggs and vanilla to the bowl. Then beat for another 2 to 3 minutes until the mixture is pale yellow and thick.
Add the flour, cocoa powder, and salt. Mix on low speed until ingredients are just incorporated. Pour in the milk and beat until smooth.
Pour the batter into the prepared pan, and spread it into an even layer.
Bake for 20 to 25 minutes until a toothpick inserted into the center of the pan comes out clean or with just a few crumbs attached to it.
Let the brownies cool.
Place the heavy cream in a medium bowl. Microwave in 20-second increments until the cream is very hot but not boiling.
Add the chopped chocolates to the cream. Let sit for a minute, then stir until a smooth chocolate mixture forms. Stir in the butter and vanilla extract until melted.
Pour the chocolate over the top of the brownies. Use a spatula to spread the chocolate into an even layer. Add the sprinkles on top of the chocolate.
Chill the brownies until they set, about 2-3 hours up to overnight. Use the parchment to lift the brownies out of the pan.
Allow to come to room temperature for 20-45 minutes. Cut into squares and serve.
Notes
Lining the pan with parchment paper will allow you to lift the entire square of baked brownies out of the pan for easier cutting once cooled.
Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to check your brownies at the lower end of the recommended baking time.
Some cosmic brownies can have nuts. Simply swap the nuts out for the sprinkles.
