Place the rolled oats in a high-speed blender and pulse until they reach a fine flour-like consistency.
Add the protein powder, egg whites, Greek yogurt, baking powder, cinnamon, vanilla extract, sea salt, and half of the banana to the blender.
Blend the mixture until completely smooth and let the batter rest for five minutes to thicken.
Heat a large non-stick skillet over medium-low heat and lightly coat with a small amount of cooking spray if needed.
Pour the batter into the skillet to form three or four pancakes, cooking until bubbles form on the surface, then flip and cook until golden.
While the pancakes cook, slice the remaining half of the banana into thin rounds.
Remove the finished pancakes from the pan, add the ghee to the same skillet, and sauté the banana slices for one minute per side until caramelized.
Stack the pancakes on a plate and top with the warm caramelized bananas to serve.
