Just cream together butter, powdered sugar, vanilla and drizzle in some milk. I don't have any measurements for that. Maybe use the same measurements above only omit the Crisco? But I almost never buy frosting. You can also add cocoa to either of these recipes to make chocolate. Again, no measurements. Just add a little and keep adding until you get the desired flavor. Always add more milk if its too thick or more powdered sugar if its too thin.
