Add rolled oats to a high-speed blender and pulse until they reach a fine, flour-like consistency.
Incorporate the egg whites, Greek yogurt, half of the banana, vanilla, cinnamon, baking powder, and sea salt into the blender and process until completely smooth.
Heat a large non-stick griddle or skillet over medium-low heat and lightly coat with a clean cooking spray if necessary.
Pour the batter onto the skillet to form four pancakes, cooking for about 3 minutes until the edges are firm and bubbles appear on the surface.
Flip the pancakes carefully and cook for an additional 2 minutes until they are golden and cooked through.
While the pancakes finish, slice the remaining half of the banana into thin rounds.
In a small separate pan, melt the ghee over medium heat, then add the banana slices and drizzle with honey.
Sauté the bananas for 1 minute per side until they are beautifully caramelized and soft, then serve immediately over the warm pancake stack.
