Preheat oven to 350°. Spray a 9X5" loaf pan with non-stick spray. Then add two strips of Reynolds Parchment Paper, one for each direction of the pan; for easy removal.
In a medium bowl, combine flour, sugar, baking powder, baking soda, and salt.
In a mixing bowl, mix bananas, peanut butter, yogurt, egg, vanilla, and oil. Fold in flour mixture until no streaks of flour remain, then gently fold in chocolate chips. Pour batter in prepared loaf pan and bake 40-50 minutes, or until toothpick comes out clean.
Cool in pan on wire rack 15 minutes before removing using the parchment paper. Allow to cool completely before slicing.
