While trying to find out if Mickey cakes are still made, and/or the name of the bakery(ies) that made them, I ran across the Banana Flips.
They were first named Banana Dreams, then renamed Banana Dream, and finally Banana Flip.
They are still available from:
According to the Patent & Trademark Ofice they are owned by the same folks that own Hostess and about 50 other brands.
It also appears they will ship them to you.
Any help with Mickey Cakes would be appreciated, and can be posted here or emailed to me at the current year at bobby.net, ie. firstname.lastname@example.org
(hopefully this confuses the address collection bots).
