Bake cake according to package instructions. When cooled, crumble cake into a bowl. Mix in one container of frosting of your choice into the cake until thoroughly combined. Begin rolling up mixture into cake balls. Place on paper lined sheet pan and refrigerate. When chilled, insert candy stick into cake pop. Melt dipping chocolate. Dip cake pop into melted chocolate. Let cake pops drain for a few seconds and then place back on paper lined sheet pan. Refrigerate until hardened. Decorate with drizzled melted chocolate and sprinkles. For Store-bought Frosted Cake, just crumble, mix and roll into balls. Use more icing if needed to bind together.
