Probably some of their remnant stock from 1956. For Twinkies, that passes for fresh. Man, I’ve always hated those things. They were cheap and ended up in lots of lunch sacks back in the day before universal school lunches.
Ah, the venerable Twinkies! I like them with peach slices and the peach syrup from the can poured over the mix. You can also make a no cook apple pie with Twinkies and apple pie filling. But putting a couple of dips of ice cream on two or three Twinkies is just decadent.
