Preheat oven to 425 degrees F. Line a muffin tin with paper liners.
Sift together the flour, baking soda, baking powder, salt and cinnamon; set aside.
Combine bananas, brown sugar, honey, egg, melted oil (or butter), milk and vanilla in a large bowl. Fold in the flour mixture and mix until smooth. Fold in the chocolate chips until combined, then spoon into muffin liners, filling them to the top.
Bake for 5 minutes, then lower the temperature to 350 degrees and continue to bake for 13 to 15 minutes or until a toothpick inserted in the center comes out clean. Allow the muffins to cool for 5 minutes, then transfer to a wire rack. Keep covered at room temperature for 3 to 4 days or in the refrigerator for up to 1 week.
Notes
Bananas should be very ripe with many brown spots.
You can use 1-to-1 gluten free flour instead of all-purpose flour.
You can use 1/4 cup granulated sugar instead of the honey.
You can use dairy free milk.
Use mini or regular chocolate chips.
You can omit the chocolate chips, if desired.
Store in a container at room temperature for up to 3 days or freeze, if desired.
