Assuming a person has some experience in a kitchen, it is simple to make homemade chocolate cake frosting. Many frosting recipes require no heat, and can be altered in thickness with ease.
A recipe on Simply Scratch's website uses only five ingredients. The recipe requires 3 cups of powdered sugar, 3/4 cup of unsweetened cocoa powder, one stick of softened unsalted butter, 1/4 cup of whole milk, and 1/4 teaspoon of pure vanilla extract. The sugar and cocoa are sifted and set aside. The butter and vanilla extract are mixed and creamed. The sifted cocoa powder and sugar are added to the cream mix gradually with the milk, and the recipe is complete.
