In a medium mixing bowl, mash half of the banana until smooth and creamy.
Whisk in the liquid egg whites, nonfat Greek yogurt, and vanilla extract until the wet ingredients are well combined.
Gently stir in the oat flour, baking powder, ground cinnamon, and sea salt until a thick pancake batter forms.
Pre-heat a large non-stick skillet over medium heat and lightly coat with a touch of cooking spray if necessary.
Pour the batter into the skillet to form three or four medium pancakes, cooking for 3-4 minutes until bubbles appear on the surface.
Carefully flip the pancakes and cook for an additional 2 minutes until they are golden brown and cooked through.
While the pancakes finish, slice the remaining half of the banana into rounds.
In a separate small skillet, melt the ghee over medium heat and sauté the banana slices for 1-2 minutes per side until caramelized.
Stack the warm pancakes on a plate, top with the caramelized banana slices, and finish with a drizzle of pure maple syrup.
