Makes about 4 cups’ worth, so you can halve the recipe if you are going to spreading the frosting rather than piping it.
½ cup nonhydrogenated shortening
½ cup nonhydrogenated margarine (we use Earth Balance)
3 ½ cups confectioners’ sugar, sifted if clumpy
1 ½ tsp vanilla extract
¼ cup plain soy milk or soy creamer
Beat the shortening and margarine together until well combined and fluffy. Add the sugar and beat for about 3 more minutes. Add the vanilla and soy milk. Beat for another 5 to 7 minutes until fluffy.
