Notes
Use very ripe bananas for the best flavor.
Substitute oat flour with all-purpose flour if needed.
Do not overmix once flour is added to keep bread tender.
Wrap tightly and store at room temperature up to 2 days or refrigerate up to 5 days.
Freeze whole or sliced—thaw and lightly toast to refresh.
