how about funnel cake?
Vanilla cream soda -- the kind you used to be able to get when drugstores had soda fountains and lunch counters (showing my age again...sigh).
Edit: Actually, it might be a nice marketing hook to have a "Soda Fountain" line of products, all designed to taste the way that drinks used to before the advent of monster-sized soft drink companies, chemical additives and FDA regulations -- true root beer, cream soda, orange crush, sarsaparilla, chocolate cream egg, vanilla cream egg, etc
