There are many different versions of Stack Cake out there, this one is more like the "old fashioned" style that used to be used in southern mountain towns. There is actually a little bit of history that goes with these cakes, which is kind of neat. Cakes used to be (and still can be) quite expensive. So when small towns would have town gatherings, like a barn dance, each family would make and bring one layer of a cake and it would be assembled (or stacked) using dry spiced fruit or apple butter.
