I always thought a weight watcher's cake had to be invisible. Seriously, you can make a cake from scratch and use pureed fruit instead of part of the shortening. And if it's a 2 egg cake you can cut the recipe in half so you don't have quite as much cake sitting around to tempt you. Whole wheat flour can be substituted about 1/4 of the flour; more than that and the cake is way too heavy and doesn't rise well. I've never heard of soda being added to a cake. That's a different idea.
