In a high-speed blender, combine the liquid egg whites, Greek yogurt, rolled oats, half of the banana, vanilla extract, cinnamon, baking powder, and sea salt.
Process the mixture until the batter is completely smooth and the oats are fully pulverized.
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 small 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.
While the pancakes finish, slice the remaining half of the banana into thin rounds.
Remove the pancakes from the pan, add the remaining coconut oil, and sear the banana slices for 1 minute per side until they become golden and caramelized.
Stack the pancakes on a plate and top with the warm caramelized banana slices.
