Here you go, Rachel, this is for you.
A 2 lb bag of powdered sugar
1 cup shortening, (crisco, please)
2 cubes butter softened
5 TBS water
1 TBS. clear vanilla (You can use regular vanilla, it will just make the frosting yellower)
Mix it all up until nice and smooth, then eat it, right out of the bowl, YUMMY.
(You know Frosting Fingers)
Ok, or put it on a cake. I have omitted 1/2 cup of powdered sugar and added 1/2 cup of cocoa powder to make chocolate buttercream, in case you are interested in that as well.
