This easy to make, 6-ingredient recipe for The Best Brownie Frosting makes enough thick chocolate icing for a 9x13 pan of your favorite brownies!
Place softened, room temperature butter (NOT melted), unsweetened cocoa powder, light corn syrup, and vanilla extract in a medium sized bowl. Stir until fully combined.
Add the powdered sugar, along with 2-3 Tablespoons of milk. Give the frosting a good stir until this is completely mixed together. You will want frosting to be thick, creamy and spreadable. If too thick, add a couple drops more of the milk. If too thin, simply add a bit more powdered sugar.
Once you've made your brownies, whether homemade or box mix, remove brownies from oven, and LET THEM COOL COMPLETELY BEFORE FROSTING. Spread frosting over top of brownies. Once completely covered with frosting, let them rest for 10-15 minutes. This gives the frosting time to slightly firm up. Slice and serve your brownies, and enjoy!
NOTE: The recipe calculation is for the entire batch of frosting. Since a 9x13 pan of brownies is typically cut into 24 servings, the caloric calculation for each serving of frosting averages out to about 74 calories (per serving of frosting).
