Place the rolled oats into a high-speed blender and pulse until they reach a fine flour consistency.
Add the liquid egg whites, half of the medium banana, half of the Greek yogurt, cinnamon, baking powder, vanilla, and sea salt to the blender; process until the batter is completely smooth.
Heat a large non-stick skillet over medium heat and lightly coat with half of the coconut oil.
Pour the batter into the skillet to form three or four pancakes, cooking for 3-4 minutes until bubbles form on the surface.
Flip the pancakes carefully and cook for another 2 minutes until they are golden brown and set through the center.
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 they are caramelized and fragrant.
Stack the pancakes on a plate, top with the remaining cold Greek yogurt, and finish with the warm caramelized banana slices.
