I found a surprise box of tagalongs in my pantry from who - knows - when that I've been resisting eating for a whole week! (naturalsweetrecipes.com)
These cookies are just like Tagalongs, the Girl Scout Peanut Butter Patties, only better! (responsibleeatingandliving.com)
So they have always been called Tagalongs in California, but 2 years ago they changed the name to Peanut Butter Patties (and Trefoils were changed to Shortbread something something, and Samoas was no longer a politically correct name)... though I'm pretty sure they all changed back to their original [to us] names this year!
