Start by preheating the oven to 350 degrees F and greasing a muffin tin with coconut oil.
Next, add the banana to a mixing bowl, and mash.
Add the eggs, maple syrup, milk, and coconut oil. Mix well.
Add the dry ingredients and mix.
Pour the batter into the greased muffin tins, filling them about 1/2 way.
Bake for 30-40 minutes or until a toothpick inserted into the center comes out clean.
Allow to cool for 10 minutes before removing from the muffin tin.
