In a medium mixing bowl, mash half of the banana with a fork until it reaches a smooth consistency.
Whisk in the eggs, non-fat Greek yogurt, and vanilla extract until the wet mixture is well combined.
Fold in the vanilla protein powder, ground cinnamon, baking powder, and sea salt, stirring until the batter is thick and uniform.
Lightly grease a large non-stick skillet with a small amount of ghee and set over medium-low heat.
Spoon the batter into the skillet to form three small pancakes, cooking for 3-4 minutes until bubbles form on the surface.
Carefully flip the pancakes and cook for an additional 2-3 minutes until they are golden brown and cooked through.
Remove the pancakes from the pan, add the remaining ghee, and sauté the remaining banana slices for 1 minute per side until golden.
Plate the pancakes in a stack and top with the warm, caramelized banana slices for a naturally sweet finish.
