Line a muffin tin with 12 liners and spray with cooking spray.
In a large mixing bowl, mash the bananas (I find a pastry cutter works great to do this!) and combine with eggs, coconut oil, vanilla, and maple syrup. Mix until combined.
Combine the dry ingredients together, and then mix into the wet ingredients.
Cook for about 20 minutes, until the tops of the muffins are browning. Allow to cool before eating, otherwise the muffin liners may stick. Enjoy!
Notes
Using room temperature coconut oil, not melted, will help the muffins retain moisture but not feel greasy.
