In a large mixing bowl, combine 1/2 cup of butter or margarine and 1/2 cup of solid vegetable shortening. Using an electric mixer, beat the mixture until it is light and airy. Add 1 teaspoon of vanilla extract to the mixture, and beat it again.
With the mixer on medium speed, slowly add 1 cup of sugar at a time, and regularly scrape the bottom and the sides of the bowl. Once the mixture is well combined, the icing appears dry. Slowly add 2 tablespoons of milk while continuing to beat the mixture at medium speed. To avoid drying out the icing, cover it with a damp cloth until use.
If the cake requires a thinner icing, add 2 tablespoons of milk, water or corn syrup. To make a stiffer icing, replace the butter in the first step with an additional 1/2 cup of shortening and 1/2 teaspoon of no-color butter flavor.Learn more about Desserts
