In a high-speed blender, combine the liquid egg whites, cottage cheese, oat flour, half of the banana, cinnamon, vanilla, baking powder, and sea salt.
Blend on high for 30-45 seconds until the batter is completely smooth and slightly aerated.
Heat a large non-stick skillet over medium-low heat and lightly coat with a small amount of ghee if necessary.
Pour the batter into the skillet to form 3 or 4 small pancakes; cook for 3 minutes until bubbles form on the surface, then flip and cook for another 2 minutes until golden brown.
While the pancakes are finishing, slice the remaining half of the banana into thin rounds.
In a separate small skillet, melt the ghee over medium heat and add the banana slices and maple syrup.
Sauté the bananas for 2 minutes until they are soft and the syrup has thickened into a fragrant glaze.
Stack the pancakes on a plate, top with the caramelized banana slices, and drizzle any remaining warm syrup from the pan over the top.
