In a high-speed blender, combine the liquid egg whites, Greek yogurt, vanilla protein powder, oat flour, cinnamon, baking powder, and sea salt.
Pulse the mixture until the batter is completely smooth and well-incorporated.
Heat a large non-stick skillet over medium-low heat and lightly coat the surface with 0.5 tsp of coconut oil.
Pour the batter into the skillet to form three or four small pancakes, cooking for approximately 2-3 minutes until bubbles form on the surface.
Flip carefully and cook for another 2 minutes until the edges are set and the centers are springy.
While the pancakes finish, slice the banana into 1/2-inch thick rounds.
In a separate small pan, heat the remaining 0.5 tsp of coconut oil and the maple syrup over medium heat until bubbling.
Add the banana slices to the syrup and sear for 1 minute per side until they develop a rich, golden syrupy glaze.
Stack the pancakes on a plate and top immediately with the warm caramelized bananas and any remaining glaze from the pan.
