In a small bowl, combine the Greek yogurt, 1 tablespoon protein powder, and 1 tablespoon almond milk. Stir until smooth and creamy. Set aside.
Add the rolled oats to a food processor or high-speed blender and blend until a fine flour forms.
Add the remaining protein powder, baking powder, and cinnamon. Pulse to combine.
Add the mashed banana, egg white, and 2 tablespoons almond milk.
Blend until the batter is smooth.
Heat a non-stick skillet or griddle over medium heat and lightly coat with cooking spray.
Pour the batter onto the skillet, forming 3 to 4 medium pancakes.
Cook until bubbles begin to form on the surface, about 2–3 minutes.
Carefully flip and cook for another 1–2 minutes until golden and cooked through.
Transfer the pancakes to a serving plate.
Top the Strawberry Banana Protein Pancakes with the protein yogurt topping and chopped strawberries.
Serve immediately.
