- For a healthier twist, substitute half the flour with whole wheat flour.
Pro Tips

- Use very ripe bananas with brown spots for the best sweetness and flavor.
- Do not overmix the batter; stir just until combined to keep muffins tender.
- Let the oats soak in the batter for 5 minutes before baking for a softer texture.
- Use paper liners or grease the tin well to prevent sticking.
- Fill muffin cups about ¾ full for nicely domed tops.
- Test with a toothpick in the center; it should come out clean or with a few crumbs.
- Let muffins cool in the pan for 5 minutes before transferring to a rack.
- For extra moisture, add a spoonful of Greek yogurt or applesauce.
