Bake yellow cake according to directions. Once mostly cooled, crumble into a bowl. Stir in chocolate frosting until completely combined into a dough. Roll into small balls. Insert toothpicks for easy dipping and freeze for 1-2 hours.
Once the cake balls are hardened, melt your chocolate. Right after dipping them in chocolate, dip the tops in the candy, and place on wax paper, candy side down, for at least an hour to dry.
