Preheat over to 375 degrees. Coat a muffin tray with cooking spray.
Mix together the flours, baking soda, baking powder, and salt together in a small bowl. In a second bowl beat sugars and softened butter. Add the mashed bananas, peanut butter, vanilla, and egg.
Stir the flour mixture into the banana mixture until just combined; add ¾ cup of chocolate chips to the batter and mix. Spoon batter evenly into the prepared muffin pan.
Bake in preheated oven for 13-15 minutes, until a tester inserted into the center of a muffin, comes out clean.
Remove from the oven and let cool for a few minutes before removing from the tray and placing on a wire rack to finish cooling. Enjoy.
