There are many trimmings besides frosting that can be used for cake decorating. Some of the common items are chocolate, candy, coconut, fruit, and nuts. Used alone or combined, these trimmings will make an interesting cake decorating design on an otherwise plain cake.
Some cake recipes may call for one or more of these trimmings because they are necessary for that type of cake, but if you have a plain cake that you want to dress up, you can use your imagination to create your own unique cake. An easy and fun cake decorating idea that the kids will love helping with is to use a Christmas tree cake pan and make your favorite cake recipe. Cover it with green frosting and then use candy to decorate it. You could use gum drops, M&M candies, Skittles, licorice, peppermint candies, candy canes . . . the choices are endless! This is just one example of many cake decorating ideas you could use.
