1 box Dixie Crystals 10x powdered sugar
1/2 c. Crisco shortening
1 tsp. clear vanilla flavoring
Dash of salt
Milk or water (about 1/4 cup; start with a little less and keep adding until icing is as thin as you want it)

Sift powdered sugar; add shortening, flavoring and salt. Add milk or water and mix with electric mixer until smooth. This icing is good on Pillsbury white cake mix and is best if kept cold in refrigerator before serving.
