Preheat oven to 375°F. In a large bowl, combine mashed banana, pumpkin puree, maple syrup, and vanilla extract.
In a small bowl, combine oat flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger. Transfer mixture to large bowl and mix together gently until well combined. Avoid over-mixing to prevent toughness in the final product. Fold in chocolate chips.
Spoon batter into silicon muffin cups and bake for 20 minutes or until the muffins are lightly browned. Remove muffins from the oven and let cool for 5 minutes. Store muffins in an airtight container.
