Prune Cake is a classic dessert that reflects the frugality and flavor of early 20th-century home baking. Moist, dense, and rich in texture, it balances the natural sweetness of prunes with a light chocolate undertone and creamy frosting. Originally popular in mid-century kitchens where nothing went to waste, prunes provided moisture and nutrition. This cake’s charm lies in its old-fashioned ingredients, yielding a treat that’s both comforting and unique.
