What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use bananas that are heavily speckled or fully brown for maximum natural sweetness and moisture.
- 2Fold the dry ingredients gently until just combined to avoid dense, gummy muffins.
- 3Rotate the muffin pan halfway through baking to ensure even golden domes.
- 4Cool muffins in the pan for exactly 5 minutes before transferring to a wire rack to prevent sogginess.
- 5Store leftover muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months.
- 6For extra rise, let the batter rest for 5 minutes after mixing so the oat flour hydrates and the leaveners activate.
