approximately 1/3 cup warm water [add extra if required]
Beat all ingredients together with electric mixer until smooth & shiny. It should be the consistency of whipped cream. Thin with water if required.
I really recommend this activity to do with your children. Coming up with ways of using the lollies you give them is a great exercise in imagination. I piped the icing & let them decorate as they wanted. You can't see in the photo but this house has ducks in a pond out front & sharks in a pool out back!!
