Place the rolled oats into a high-speed blender and pulse until they reach a fine, flour-like consistency.
Add the liquid egg whites, Greek yogurt, half of the banana, ground cinnamon, vanilla extract, baking powder, and sea salt to the blender and process until the batter is completely smooth.
Heat a large non-stick skillet over medium-low heat and lightly coat with a tiny amount of ghee if necessary.
Pour the batter into the skillet to form three or four small pancakes, cooking for 3-4 minutes until bubbles form and the edges are set.
Flip the pancakes carefully and cook for another 2 minutes until golden brown, then remove from the pan and set aside.
Slice the remaining half of the banana into rounds.
In the same skillet, melt the 1 tsp of ghee over medium heat and add the banana slices in a single layer.
Cook the bananas for 1-2 minutes per side until they are caramelized and deeply golden.
Top the warm pancakes with the caramelized bananas and serve immediately.
