These are absolutely heavenly and oh so lite in taste. A wonderful little decadence that you don't mind cheating a little while dieting. I make them into cupcakes but the recipe actually is for a cake. The serving size is a guess. If you make them into cupcakes, make sure you fill them all the way to the top as they don't puff up that much. The frosting makes a huge amount and so adjust accordingly depending on if you're making cupcakes or a cake.
