Here's what you do:
Take your favorite sugar cookie recipe. And instead of spending hours rolling the dough flat, cutting shapes with cookie cutters, and essentially having flour all over every crevice in your kitchen, make little dough balls and flatten them with your hands. Shhh. Don't tell Martha. It works just as good and takes half the time.
For the glaze:
Beat all ingredients well. Separate about 3/4 cup of the glaze into another bowl and add desired food coloring. Put the colored glaze into a pastry bag with a small writing tip.
