Preheat oven to 425 F. Line a 12 count muffin pan with paper liners. Melt the butter in the microwave. Allow to cool to room temperature.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Set aside.
Place the peeled overripe bananas on a plate. Mash them with a fork. Set aside.
In a large bowl, whisk together the brown sugar, butter (melted, cooled to room temperature butter) and oil. Whisk in the eggs, vanilla and mashed bananas.
Use a spatula to stir in the dry ingredients until just combined and there are only a few streaks of flour remaining Do not overmix.
Fold in the chopped chocolate or chocolate chips until just combined. Avoid overmixing.
Divide batter evenly in the 12 muffin cups. Top with extra chocolate chunks (optional).
Bake at 425 F for 8 minutes. After 8 minutes, reduce heat to 350 F. (Do not open oven door, just reduce temperature and continue baking). Bake an additional 7-8 minutes until a toothpick comes out clean or with only a few moist crumbs when inserted into the center of a muffin.
Let muffins cool in the muffin pan for about 10 minutes then remove and set them on a wire rack.
