While lower in fat than most Lemon Pudding Cakes, the buttermilk gives this dessert a rich, full bodied flavor. Try it both warm and chilled. The cake is light as a feather while warm and the pudding is runny, more like a sauce. When chilled, the cake has a firmer texture and the pudding thickens and permeates the cake. Its good served with whipped cream; or a raspberry sauce.
