This recipe is very versatile and heavily addictive. You can mix and match cake and icing flavors as well as the chocolate coatings. The variations are unlimited, and they can be nicely packaged and given as gifts.
If you want to go the extra mile, cake balls can be rolled in nuts, sprinkles, coconut, etc. or double-dipped in white and dark chocolates. White chocolate confectioners' coating is also called Almond Bark in some stores.
