Preheat the oven to 375. Prepare your 12 count muffin tin - either grease the cups or add in muffin liners. Set aside for now.
Add the bananas to a large bowl. Mash the bananas up with a fork until they are fully mashed, with minimal banana lumps left. To this bowl, add in your maple syrup, melted butter, and egg. Mix well with a whisk.
To this bowl, add in the all purpose flour, cinnamon, baking soda and salt. Mix together gently with a wooden spoon until all ingredients are combined and no streaks of flour are left.
Grab your prepared muffin pan. Fill the muffin cups until ⅔ full. Bake for 20-24 minutes or until a toothpick can be inserted and comes out clean.
Once done, let cool in the pan for a few minutes and then remove them to a cooling rack.
When ready, eat with warm maple butter. Enjoy!
