1canFrostingTraditional, not whipped
4tablespoonsSalted Butter
2tablespoonsUnsweetened Cocoa Powder
3tablespoonsWhole Milk
1 1/2cupsPowdered Sugar
Instructions
Preheat oven to 350°F. Butter and flour a 9x13 pan and set aside.
Prepare and bake cake as directed on box. Let cool completely. Crumble cooled cake into a large bowl, making sure there are no large chunks. Spoon entire can of frosting into the bowl, then combine thoroughly with a rubber spatula.
Once a thick “dough” has formed, spoon it over the brownies and spread evenly. Cover and let cool for several hours, until chilled. Prepare fudge topping.
Melt butter in a small saucepan over medium heat. Whisk in cocoa powder and milk until mixture is smooth, thick, and begins to bubble. Remove from heat and whisk in powdered sugar until smooth.
Working quickly, pour fudge frosting over brownies, spreading to the edges. Immediately top with sprinkles, if desired. Cover and chill until firm, then cut into squares.
