01 - Preheat the oven to 350°F. Line a 12-cup muffin tray with paper liners or lightly grease with cooking spray.
02 - In a large bowl, whisk together mashed bananas, eggs, melted coconut oil or butter, honey or maple syrup, and vanilla extract until smooth and fully incorporated.
03 - In a separate medium bowl, combine rolled oats, flour, baking soda, baking powder, cinnamon, and salt. Whisk to ensure even distribution.
04 - Add dry ingredients to wet ingredients. Stir gently with a spatula until just combined. The batter should remain slightly lumpy—avoid overmixing to prevent dense muffins.
05 - Gently fold in chopped nuts or chocolate chips if desired, distributing evenly throughout the batter.
06 - Divide batter evenly among the 12 muffin cups, filling each approximately 3/4 full. Use a cookie scoop or measuring cup for consistent portioning.
07 - Bake for 18-22 minutes until golden brown and a toothpick inserted into the center comes out clean or with moist crumbs.
08 - Allow muffins to cool in the pan for 5 minutes, then carefully transfer to a wire rack to cool completely before serving.
