This cake may not redefine every thought you've ever had about cranberries, but it will turn them upside down--literally.
Swapping out cranberries for the classic pineapple in this upside-down cake yields a surprisingly pleasant result: the fresh berries, while still assertively tart, are pleasingly matched by a buttery, sweet cake and a brown sugar-butter topping. The sweet-tart taste has a few advantages: first, it makes it seem vaguely healthy and therefore perfect as a breakfast cake; second, the tartness of the cranberries is sublime when paired with the sweet contrast of a big scoop of vanilla ice cream on top.
