For an extra touch of indulgence, add chocolate chips to the batter. Store muffins in an airtight container at room temperature for up to 3 days, or freeze for longer storage. If you don't have oat flour, you can make your own by grinding rolled oats in a food processor until finely ground. The riper the bananas, the sweeter and more flavorful the muffins will be.
