Place the banana, oats, egg whites, baking powder and cinnamon in a blender and mix until smooth.
Add the walnuts and pulse a few times to combine.
Heat a nonstick skillet over medium heat. Pour 1/3 of the batter into the pan forming a 3-inch pancake. Set a timer and cook for 2 minutes. If adding chocolate chips, sprinkle them when bubbles begin forming on the surface. Flip and cook for another 1-2 minutes on the opposite side.
Repeat with the remaining batter.
Serve with maple syrup, additional fruit, nuts or a dollop of yogurt.
Notes
This recipe is denser than a typical pancake so be sure to keep the heat at medium and cook for the full 2 minutes per side until they are golden brown.
You can add 1 scoop of protein powder to the recipe along with the other ingredients if you would like even more protein. However it will change the flavour and reduce the cooking time slightly.
You can use pecans as a walnut substitute.
