Sugar Cookie Frosting
4 tbsp meringue powder (available at many supermarkets and in most craft stores)
1/2 cup water
6-7 cups confectioner's sugar (may need more or less, see the consistency advice below)
1 tsp vanilla extract
1/4 cup Crisco
Whip the meringue powder and water on high speed for a looooong time, several minutes, until it's fluffy and peaks form. Gradually add the rest of the ingredients to desired consistency. Store at room temperature in a sealed container for up to a month.
