In a high-speed blender, combine the rolled oats, vanilla protein powder, liquid egg whites, Greek yogurt, half of the banana, cinnamon, vanilla extract, baking powder, and sea salt.
Process the mixture on high until the batter is completely smooth and creamy.
Slice the remaining half of the banana into thin, even rounds.
Heat a large non-stick skillet over medium-low heat and add the ghee, swirling to evenly coat the surface.
Pour the batter into the skillet to form three or four medium-sized pancakes.
Carefully place the reserved banana slices onto the wet surface of each pancake, pressing them slightly into the batter.
Cook for 3-4 minutes until bubbles form on the surface and the edges look set and dry.
Flip the pancakes carefully and cook for another 2 minutes until the banana slices are beautifully caramelized and the pancakes are cooked through.
Transfer to a plate and enjoy immediately while the fruit is warm and tender.
