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, vanilla extract, ground cinnamon, and sea salt to the blender.
Blend on medium speed for 30 seconds until the batter is completely smooth and aerated.
Peel the banana and slice it into thin rounds, approximately 1/4 inch thick.
Heat a large non-stick skillet over medium heat and melt the coconut oil, swirling to coat the surface.
Pour the batter into the skillet to form three or four medium-sized pancakes.
Immediately press 3-4 banana slices into the wet surface of each pancake while they are still cooking on the first side.
Cook for 3-4 minutes until the edges are set and bubbles appear on the surface.
Carefully flip the pancakes and cook for another 2 minutes, allowing the banana slices to caramelize and turn a deep golden brown.
Transfer the pancakes to a plate with the caramelized banana side facing up.
Garnish with a sprinkle of hemp seeds for added texture and serve immediately.
