Moist and flavorful these can be made with oat or wheat bran depending on what you have. You can put your choice of nuts (my fav is walnuts) or dried fruit and vary the amount of mashed banana and they still come out great. Since I started using this recipe 5 years ago, I have kept these muffins on hand in our freezer. I save my brown bananas, freeze them and when I get a good amount puree them in my cuisinart so I can triple the batch of muffins. You can also make these as regular size muffins. The batch would make 12 muffins and bake time would decrease to 15 minutes or so.
