Place the liquid egg whites, Greek yogurt, rolled oats, hemp seeds, half of the banana, cinnamon, vanilla, and sea salt into a high-speed blender.
Process the mixture until completely smooth and the oats are fully incorporated into a pourable batter.
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 medium pancakes, cooking for 2-3 minutes until bubbles form on the surface.
Flip the pancakes carefully and cook for another 2 minutes until the edges are golden brown and the centers are set.
While the pancakes finish, slice the remaining half of the banana into thin rounds.
Remove the pancakes from the pan and add the remaining coconut oil and the maple syrup to the same skillet.
Add the banana slices to the skillet and sear for 1 minute per side until they become soft and caramelized.
Stack the pancakes on a plate and top with the warm caramelized banana slices and any remaining syrup from the pan.
