1/2 cup solid vegetable shortening
1/2 cup softened butter or margarine
1 tsp vanilla extract
4 cups powdered sugar
2 T or so if milk
In large bowl, cream shortening and butter with electric mixer. Add vanilla. Gradually add sugar, one cup at a time, beating well on medium speed. Scrape sides and bottom of the bowl often. When all sugar has mixed in, icing will appear dry. Add milk and beat at medium speed until light and fluffy. Keep bowl covered with a damp cloth until ready to use. For best results, keep icing bowl in refrigerator when not in use. Refrigerated in a tight container, this icing can be stored for 2 weeks. Rewhip before using. Makes 3 cups.
