I have not tested this recipe but it's very similar to mine. I think this a great recipe because it does not call for flour and so this makes it a true unprocessed bran muffin. I actually substitute the sugar with agave nectar because the latter has a lower glycemic index. In addition to the oatmeal and oat bran, I use wheat bran for added fiber. I also add reduced fat or regular organic coconut flakes which makes it even tastier. I also use almond milk instead of dairy milk. I like the idea of using apple sauce and I will try this too.
