In a high-speed blender, combine the rolled oats, liquid egg whites, Greek yogurt, half of the banana, cinnamon, vanilla, baking powder, and sea salt.
Blend until the batter is completely smooth and let it sit for 2 minutes to allow the oats to hydrate and thicken.
Heat a non-stick skillet over medium-low heat and lightly coat with half of the ghee.
Pour the batter into the skillet to form pancakes, cooking for 3 minutes until bubbles form on the surface and the edges are set.
Flip the pancakes and cook for another 2 minutes until the centers are firm and the outsides are golden brown.
Remove the pancakes from the pan, then add the remaining ghee and the other half of the banana (sliced) to sauté until caramelized and soft.
Stack the pancakes on a plate, top with the warm caramelized bananas, and finish with a drizzle of pure maple syrup.
