This is the icing that I used on my 4th of July Red, White and Blue Tie-Dye (rainbow type) cupcakes. It was very good and super simple and fast to make. 4 cups confectioners’ sugar 1 cup shortening 2 tablespoons water 1 teaspoon clear imitation vanilla extract Directions In a large bowl, combine sugar, shortening, water and vanilla. Beat on low speed to combine, then beat on medium speed for a full five minutes. It won’t look like Icing at first, but keep the mixer going for a full five minutes, and then you’re done! Note: If you’re not using this for decorating, but just for icing the cake, thin the icing by adding 3 tbs. of corn syrup, or water to the icing. in the UK shortening is available under brand names such as Cookeen, Trex, White Flora, etc.
