This Southern dessert begins with a thick cake batter. Once the batter is in the pan or oven-safe dish, gently spoon boiling water over the top. The water and batter blend while baking to form the pudding layer. Try Hot Fudge Brownie Cake capped with a fluff of whipped cream or Apple Pudding Cake flavored with apple juice, freshly chopped apples, and cinnamon. Serve warm, and enjoy.
