Rum Buttermilk Butterfinger Cake

A Butterfinger bar’s crunchy center elevates it to the top of the Halloween candy list. Or is it the buttery, caramelized flavor lurking behind a thin layer of chocolate? Or is it the fact that many of us do not permit ourselves the treat of candy except at Halloween. And Valentine’s Day. And Easter. Hmmm. Maybe scratch that thought about discipline and deprivation.
