Sugar Trees in a snowy meadow of Icing. Sugar cookies have stood the test of time down through the generations; you may remember your own grandmother or mother baking sugar cookies in her kitchen. Rolling out and cutting sugar cookies takes a little more effort than drop or bar cookies, but this is a wonderful and traditional recipe; the dough doesn't spread and the cutout cookies keep their shape when baked. I have included a basic recipe for confectioners sugar icing along with recipes for Royal Icing. Royal Icing made with egg whites is generally not consumed but is great for non-edible decorations such as gingerbread houses or tree ornaments. Since the egg whites are not cooked there is a greater risk of salmonella. Royal Icing made with meringue powder is safe to eat
