I've hesitated posting a low fat coffee cake recipe. My philosophy on baked goods is "If you have to ask, you can't afford it." I say this as someone who has lost 50lbs in a year. I'm not trying to be flip, but the ugly truth is that you need some fat in baked goods to make them taste good. Nevertheless, I realize that others might count calories and fat grams. I've done a couple of things to try to retain the taste and texture: (1) I've substituted oat flour for some of the wheat flour as oat flour contains more fat; (2) I've added spices and orange zest for flavor. There is no icing or crumb topping on this cake...only chopped apples with cinnamon sugar.
