After I posted those decades-old Planters packages, I remembered I had something more recent.
Here's a package for a snack/cookie product that seems to be universally missed; P.B. Crisps.
What you got with these was a crunchy peanut-shaped cookie filled with peanut butter goodness. How can you go wrong with that?
There were apparently other flavors like chocolate, and maybe even PB&J, but I don't recall those myself.
