The Duchess Bakes a Cake by Virginia Kahl. My mother checked this out for me and my sister when we were tiny army brats in occupied West Germany. A nice tale, with figures inspired by medieval manuscript tradition. The Duchess bakes a cake that goes out of control, mounting sky-high, forcing the castle's residents to eat everything to calm the situation. So what started out as a thin cast of characters ends up with the same as rendered pleasantly plump at the end.
