Preheat the oven to 350F with the rack in the middle position and grease your mini muffin pans.
In a mixing bowl, combine flour, baking powder, baking soda, salt and cinnamon. Set aside.
Cream together butter and maple syrup using a stand mixer (if you have or hand mixer if you don’t) until smooth. Don't worry if the butter chunks up. Add eggs one at a time and beat until smooth. Then add bananas one at a time and mix until combined.
At low speed, add dry ingredients a little bit at a time until fully mixed together.
Fold in chocolate chips and pecans.
Spoon batter into mini muffin tins and bake for 10-12 min or until golden brown.
Let cool for about 10 minutes and then remove from the muffin pan and set on wire rack to fully cool before you enjoy.
