Do you call it Whoopie Pie or Cookie Sandwich? I would have called it Cookie Sandwich growing up, but my S-I-L introduced me to the Whoopie Pie (she's got my back like that!) when I entered the Oberholzer family and learned the ways of Pennsylvanians. I believe the Whoopie Pie is a PA thing, but I'm not entirely sure. Either way it's a yummolicious thing!
This particular one involves cake mix and cream cheese and is EASY. Click here for the recipe!
