Place all ingredients except the chocolate chips into a blender and blend until smooth. Stir in the chocolate chips.
Heat a non-stick skillet over medium heat with cooking spray. Once hot, pour pancake batter onto the skillet, using a 1/4 cup to measure.
Cook until the batter starts to form little bubbles and you can easily get under the pancake with a spatula. Flip pancake and cook for another 1-2 minutes or until pancake is cooked through. Continue process until you run out of batter. You should be able to make 6 small pancakes.
Stack pancakes and top with banana slices and maple syrup to serve.
