This recipe was given to me by my neighbor Claire when I lived in Framingham, Massachusetts, in 1972. I had never heard of Whoopie Pies, but I fell in love with these. If you're concerned about the raw egg whites in the frosting, buy pastuerized egg whites. I've been making this recipe as is since 1972 and no one has ever become ill from eating them. The recipe is written just as it is on my very well-worn recipe card.
