Be careful with your definition... A chocolate bar is generally something that is vaguely rectangular (longer than it is wide), has chocolate as it's outer layer, and would take multiple (often many) bites to eat. If I take a sherbet pip and dip it in chocolate, it is not a chocolate bar good sir! :-)
