Pulse the rolled oats in a high-speed blender until they reach a fine, flour-like consistency.
Add the liquid egg whites, half of the banana, vanilla protein powder, ground cinnamon, sea salt, vanilla extract, and baking powder to the blender.
Blend the mixture on medium speed for 30 seconds until the batter is smooth and slightly thickened.
Warm a non-stick skillet over medium heat and lightly grease with half of the coconut oil.
Pour the batter into the pan to form individual pancakes, cooking until bubbles appear on the surface and the edges look dry.
Flip the pancakes carefully and cook for an additional minute until they are golden brown on both sides.
Slice the remaining half of the banana into thin rounds while the pancakes finish cooking.
Remove the pancakes from the pan, add the remaining coconut oil, and sauté the banana slices until they are caramelized and soft.
Plate the pancakes in a stack and garnish with the warm, golden banana slices.
