In a mixing bowl, mash 1 banana with a fork or handheld mixer. Use a rubber spatula to fold in canned pumpkin and Greek yogurt.
Beat in maple syrup, egg, and vanilla extract.
In a separate bowl, mix together all purpose flour, pumpkin pie spice, ground cinnamon, salt, baking soda, and baking powder.
Combine wet and dry ingredients until a batter forms.
Fold in chocolate chips.
Grease a 8x4 or 9x5 loaf pan. Pour batter into the loaf pan. Sprinkle more chocolate chips on top if desired.
