Cosmic Brownie Recipe (Tastes Like the Real Thing!)
My homemade, completely from-scratch cosmic brownie recipe tastes like the real thing, minus all the preservatives. These are quick and easy to make with no mixer and just 30 minutes of prep work!
Prepare a 13x9 pan by lightly greasing and flouring, or line with parchment paper. Preheat oven to 350F.
Place butter in a large, microwave-safe bowl, and microwave until completely melted.
Stir in cocoa powder.
Add sugars, and stir well.
Add eggs, one at a time, stirring well after each addition.
Stir in vanilla extract. Set aside.
In a separate, medium-sized bowl, whisk together flour, cornstarch (cornflour for UK), and salt.
Gradually stir dry ingredients into wet until completely combined.
Evenly spread into prepared pan and bake on 350F (177C) and bake for 16-18 minutes. Allow to cool completely before frosting.
Frosting
Combine chocolate chips and heavy cream in a medium-sized saucepan over medium-low heat. Stir well until chocolate is completely melted and mixture is smooth.
Remove from heat and stir in vanilla extract and salt. Allow to cool 5-10 minutes before proceeding.
Evenly pour frosting over brownies, using a spatula to spread evenly.
Immediately sprinkle candy chips over top. Allow frosting to harden (about 1 hour) before cutting and eating (this can be sped up if you place the brownies in the refrigerator for about 15 minutes).
