01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease with oil or butter.
02 - In a large bowl, mash the bananas thoroughly. Whisk in eggs, honey or maple syrup, milk, vanilla, and melted coconut oil until smooth and well combined.
03 - In a separate bowl, mix together oats, baking powder, cinnamon, and salt until evenly distributed.
04 - Add dry ingredients to the wet mixture and stir until just combined. Gently fold in any optional add-ins if desired.
05 - Divide the batter evenly among the muffin cups, filling each about 3/4 full.
06 - Bake for 22 to 25 minutes, or until the centers are set and the tops are lightly golden brown.
07 - Allow to cool in the pan for 5 minutes, then transfer to a wire rack. Serve warm or at room temperature with a dollop of Greek yogurt and optional toppings.
