The frosting is a spreadable consistency similar to peanut butter. We usually use a spatula to spread it on top and around the cake. It can be made smooth with a warm bench scraper for a perfectly smooth cake. The icing is a thinner consistency than frosting. It can be poured or spreadable similar to what we use on cinnamon rolls and loaf cakes. A glaze is pouring consistency. The best way to use it is to pour it on a cake to achieve a smooth finish.
