In a high-speed blender, combine the rolled oats, liquid egg whites, Greek yogurt, half of the banana, cinnamon, baking powder, vanilla, and sea salt.
Blend on high until the batter is completely smooth and the oats are fully processed into a flour-like consistency.
Heat a large non-stick skillet over medium heat and lightly coat with a small amount of cooking spray if needed.
Pour the batter into the skillet to form three or four small pancakes, cooking for 2-3 minutes per side until golden brown and firm.
While the pancakes cook, slice the remaining half of the banana into thin rounds.
In a separate small skillet, melt the grass-fed ghee over medium-high heat and add the banana slices.
Sear the bananas for approximately 1 minute per side until they develop a deep golden, caramelized crust.
Stack the warm pancakes on a plate and top with the caramelized banana slices and any remaining ghee from the pan.
