Ding dongs and ring dings are almost identical desserts made by two different companies (Drake's makes Ring Dings and Hostess makes Ding Dongs). Therefore, there are subtle differences between ring dings and ding dongs. As I mentioned before, Ring Dings are slightly larger. I find the chocolate cake interior of Ding Dongs drier but there's a higher ratio of filling. Neither store bought option is as good as homemade, IMO!
