An old-fashioned iced gingerbread loaf has been a Christmas staple for generations! It's moist, light, and warmly spiced with ginger, cinnamon, nutmeg, cloves, allspice, and molasses, for an easy breakfast, snack, or dessert that you can make in advance. Finish the cake with a vanilla citrus glaze or a dusting of powdered sugar for a festive addition to any holiday spread!
