Preheat your oven to 350°F and lightly grease a small oven-safe ceramic bowl with a touch of ghee or cooking spray.
In a medium mixing bowl, whisk together the egg whites, oat flour, 0.75 scoops of the vanilla protein powder, 4 tablespoons of the Greek yogurt, and the baking powder until the batter is smooth.
Pour the pancake batter into the prepared oven-safe bowl, smoothing the top with a spatula.
In a small ramekin, melt the ghee and stir in the ground cinnamon and coconut sugar until it forms a thick, dark paste.
Use a toothpick or knife to swirl the cinnamon mixture into the pancake batter in a circular motion to create the classic cinnamon roll aesthetic.
Bake for 18 to 22 minutes, or until the center is set and the edges have slightly pulled away from the sides.
While the bowl bakes, whisk the remaining 2 tablespoons of Greek yogurt, the remaining 0.25 scoops of protein powder, almond milk, and vanilla extract to create a creamy icing.
Remove the bowl from the oven and drizzle the protein icing over the warm pancake before serving.
