Place the rolled oats into a high-speed blender and pulse until they reach a fine flour consistency.
Add the egg whites, Greek yogurt, protein powder, half of the banana, cinnamon, baking powder, sea salt, and vanilla extract to the blender.
Blend on high until the batter is completely smooth and thickened.
Heat a large non-stick skillet over medium heat and lightly grease with half of the coconut oil.
Pour the batter into the skillet to form three or four small 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 remaining half of the banana into rounds.
Remove the pancakes from the pan, add the remaining coconut oil, and sear the banana slices for 1 minute per side until golden and caramelized.
Stack the pancakes on a plate and top with the warm caramelized banana slices.
