In a high-speed blender, combine the rolled oats, egg whites, Greek yogurt, half of the banana, vanilla extract, cinnamon, sea salt, and baking powder.
Blend until the batter is completely smooth and let it rest for 5 minutes to allow the oats to hydrate and thicken the mixture.
Heat a non-stick skillet over medium heat and lightly coat with a small amount of ghee if necessary.
Pour the batter into the skillet to form small pancakes, cooking for 2-3 minutes per side until golden brown and bubbles form on the surface.
While the pancakes are cooking, slice the remaining half of the banana into rounds.
In a separate small pan, melt the 1 tsp of ghee over medium-high heat and sear the banana slices until they are caramelized and fragrant.
Stack the pancakes on a plate and top with the warm caramelized bananas and an extra sprinkle of cinnamon.
