I think its a local thing, atleast in my part of PA. Everyone else I know calls the whoopie pies. I will have to look up how they got that name but it does have to do with coal miners and stuff. but I found my aunts' recipe to make them. I am so excited. I think I will be making them today for tomorrow. Now I am not sure about the jello cake but woot woot for gobs. I will have to take a picture of them once they are made! My aunt would also make gob cakes which were so yummy!
