This is the recipe I grew up eating and it is still my favorite! Enjoy!
3 c. powdered sugar
1/4 c. shortening
1 tsp. vanilla
Small drops of milk gradually added
Food coloring as desired
Mix all ingredients to the desire consistency with a hand mixer. This amount will frost one batch of sugar cookies or cupcakes or will fill and frost a two-layer 9 inch round cake (thin layer).
