We are going to a toddler holiday party next week and I am making cookies/frosting so that the kids can decorate. I haven't been able to find a good icing recipe though. Most recipes call for Royal Icing, which uses egg whites or powdered egg whites (which I can't find here), and since there will be pregnant moms and very young children, I don't want to use raw egg whites. Any suggestions (with links!) for good cookie decorating icing?
