Place the rolled oats into a high-speed blender and pulse until they reach a fine, flour-like consistency.
Add the liquid egg whites, Greek yogurt, vanilla protein powder, baking powder, ground cinnamon, vanilla extract, sea salt, and half of the banana to the blender.
Blend the mixture on high until completely smooth, then let the batter rest for 5 minutes to thicken.
Heat a large non-stick skillet over medium-low heat and lightly coat with half of the ghee.
Pour the batter into the skillet to form three or four medium pancakes, cooking until bubbles form on the surface and the edges appear set.
Flip the pancakes carefully and cook for another 1-2 minutes until golden brown, then remove from the pan and set aside.
Slice the remaining half of the banana into thin rounds.
Add the remaining ghee to the same skillet and sear the banana slices for 1 minute per side until they become fragrant and caramelized.
Top the pancakes with the warm caramelized bananas and serve immediately.
