My Favorite Decorator Cake Icing - cooking recipe

Ingredients

2 tablespoons Crisco or 2 tablespoons other solid shortening
1/2 cup butter, very soft
2 lbs powdered sugar, sifted
1 teaspoon vanilla
2 -4 tablespoons milk (to adjust spreading consistency)
paste food coloring

Preparation

Cream together in a stand mixer the butter and Crisco until completely blended. Add the vanilla.
Sift in the powdered sugar a little at a time, scraping down the sides of the bowl as you go. Keep sifting and blending until the whole 2 lbs. is incorporated.
If the icing is thick and will not spread easily, add 1 tablespoons of milk at a time until desired consistency is achieved.
Add food coloring. Blend well.
