Frosting sugar cookies is a time-honored holiday tradition. Whether you're whipping up a batch of sweets for Santa, pulling together some last-minute hostess gifts for Christmas parties, or crafting a fun, festive gift for your next-door-neighbors this season, sugar cookies are an easy and fun way to get into the spirit of the season. Using royal icing for your cookies will allow the frosting to harden – thus allowing you to add even more details to your treats. This royal icing recipe reigns supreme as one of the prettiest ways to dress up your favorite Southern confections. Just follow the proportions of icing sugar, meringue powder, and water, and you'll be all set. If you're interested in flooding your cookies, add a little bit of water, 1 tsp. at a time, to get your icing to flooding consistency.
