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, baking powder, sea salt, and vanilla extract to the blender.
Blend on medium speed until the batter is completely smooth and well-combined.
Heat a large non-stick skillet over medium-low heat and lightly coat with a tiny amount of ghee if necessary.
Pour the batter into the skillet to form small-to-medium pancakes, cooking for 2-3 minutes until bubbles form on the surface.
Flip the pancakes carefully and cook for another 1-2 minutes until they are set and lightly browned.
While the pancakes finish, slice the half banana into thin rounds.
Remove pancakes from the pan and melt the remaining 1 tsp of ghee in the same skillet.
Place the banana slices in the pan and sear for 1 minute per side until they become golden and caramelized.
Stack the pancakes on a plate and top with the warm caramelized banana slices.
