Preheat oven to 350 degrees F and grease a 12-cup muffin pan.
In a large mixing bowl, mix together almond flour, baking soda, baking powder, and cinnamon using a fork.
In a separate, smaller mixing bowl, take 4 ripe bananas and gently smash using a fork or potato masher. You want your bananas to still be chunky. Add vanilla extract and syrup. Gently stir to combine.
Take wet ingredients and pour into dry ingredient mixing bowl. Add egg and mix to combine everything.
Fold in chocolate chips.
Add batter to greased muffin pan. Fill to just below the top.
Top with extra banana slices, syrup, and or chocolate chips.
Bake for 25-30 min. Test at 25 min using a toothpick or small knife to gently poke through the center of one of the muffins. If the toothpick/knife comes out clean, remove muffins from oven.
Let cool before removing from muffin pan.
