In a high-speed blender, combine the liquid egg whites, Greek yogurt, rolled oats, collagen peptides, cinnamon, vanilla extract, sea salt, and half of the banana.
Blend on high for 30-45 seconds until the batter is completely smooth and the oats are fully pulverized.
Heat a large non-stick skillet over medium-low heat and lightly coat with half of the ghee.
Pour the batter into the skillet to form three or four small pancakes; cook until bubbles form on the surface and edges look set, about 3 minutes.
Carefully flip the pancakes and cook for another 2 minutes until golden brown, then remove to a plate.
While the pancakes are resting, slice the remaining half of the banana into 1/4-inch thick rounds.
Add the remaining ghee and the honey to the same skillet over medium heat.
Place the banana slices in the skillet and sear for 1-2 minutes per side until they develop a deep golden, caramelized crust.
Stack the pancakes and top with the warm caramelized bananas and any remaining glaze from the pan.
