Place the rolled oats in a high-speed blender and pulse until they reach a fine, flour-like consistency.
Add the liquid egg whites, Greek yogurt, vanilla protein powder, cinnamon, vanilla extract, baking powder, and sea salt to the blender.
Blend the mixture on medium speed until the batter is completely smooth and well-combined.
Peel the banana and slice it into thin, even rounds.
Heat the ghee in a large non-stick skillet over medium-low heat until melted and shimmering.
Place the banana slices in the skillet in small circular clusters, allowing them to sizzle for 1 minute until the natural sugars begin to brown.
Pour the pancake batter directly over each cluster of bananas to form individual pancakes.
Cook for approximately 3 minutes until bubbles form on the surface and the edges look set.
Flip the pancakes carefully and cook for another 2 minutes until the other side is golden-brown and the center is cooked through.
Serve the pancakes immediately while the caramelized bananas are warm and soft.
