A fun project to do with the kids on a blustery snow day, these Hats Off to Christmas! Cookies are just as fun to decorate as they are to eat! Serve these cute Christmas hats after your holiday feast or use them to celebrate anyone whose birthday happens to fall around the holiday season. Speaking of birthday, you could even customize these hats to be any color you'd like, making them great for birthday parties that happen anytime of year! Since these cookies are decorated with thinned flow-in icing, they will need time to dry, so be sure to allow for extra time to let the icing set.
