In a high-speed blender, combine the rolled oats, egg whites, Greek yogurt, protein powder, baking powder, cinnamon, and sea salt.
Blend on high until the batter is completely smooth and the oats are fully processed into a flour-like consistency.
Check the thickness of the batter; if it is too dense to pour easily, add one tablespoon of water and pulse briefly.
Heat a large non-stick skillet over medium heat and melt half of the coconut oil to coat the surface.
Pour the batter into the skillet to form three small pancakes, cooking for 2-3 minutes until bubbles appear on the surface.
Carefully flip the pancakes and cook for an additional 1-2 minutes until both sides are golden brown, then transfer to a plate.
Slice the banana into rounds and add them to the same skillet with the remaining coconut oil.
Sauté the banana slices for about 1 minute per side until they are caramelized and slightly softened.
Stack the pancakes and top with the warm caramelized bananas before serving.
