Dolly Madison (IBC) has inherited the banana flips from Mickey (ABC).
Flowers also used to make them, (that's what Mrs. Frehsley's would be)but the cake was always dry and gritty. They also made chocolate flips (vanilla creme) and even a vanilla flip.
I still have the paper labels from a lot of these things, and have even scanned them and used them as my desktop for a while.
I also still miss Drake's strawberry and banana Shortcakes (basically, their fake Twinkies back before the merger). And out West, the best tasting cakes I ever had were Break's (Campbell Taggart; now Earth Grains) Shake Cakes, which looked like Zingers, but were slightly longer, and came in vanilla, chocolate, and Strawberry.
These days, I have been eating Entenmann's mini carrot cakes, which are also sold in two in a pack, at least around here. They are kind of shaped like Zingers as well, but not as sugary, but tasty carrot cake. Totally unique in snack cakes.
