I love attempting healthier versions of baked goods. Some work out, and some don't. Thankfully, this Pinterest pin that my friend posted did work out:http://pinterest.com/pin/216383957066404065/
I substituted apple sauce for the mashed banana, and I also substituted oat flour for the whole wheat flour because that's what I had on hand. They made the whole house smell cinnamony good, and they had a great cinnamon flavor as well. The whole grain flour made them a little dense, but it was easy to ignore that for the amazing flavor and aroma. Best of all, my toddler gobbled them up. I had to give him half a muffin at a time because he kept asking for more.
