In a high-speed blender, combine the egg whites, Greek yogurt, protein powder, rolled oats, half of the banana, cinnamon, baking powder, sea salt, and vanilla extract.
Blend on high until the batter is completely smooth and the oats are fully processed into a flour-like consistency.
Slice the remaining half of the banana into thin, even rounds.
Heat a non-stick skillet over medium-low heat and melt the ghee, ensuring the surface is well-coated.
Place the banana slices in the skillet and cook for 1 minute until they begin to soften and turn golden.
Pour the pancake batter directly over the banana slices to form 3-4 small pancakes.
Cook for 3-4 minutes until bubbles form on the surface and the edges look set.
Carefully flip the pancakes and cook for another 2 minutes until the bottom is golden brown and the center is cooked through.
Serve immediately while the caramelized bananas are warm and fragrant.
