Blend oats, egg white, and water until the consistency is smooth (I use a Nutribullet)
Pour the mixture into a bowl and whisk it together with the protein powder and 1 tsp. Stevia (the mixture should be like thick pancake batter).
Pour half of the batter into a small (about 4.5 inches across) nonstick pan and sprinkle with two-thirds of the cinnamon and 1 tsp. Stevia. Pour the remaining batter over and sprinkle with the rest of the cinnamon.
Pull a knife through the batter a few times to slightly mix in the cinnamon and Stevia.
Bake for 25 minutes and let it rest for a few minutes before serving.
If stored in the fridge, reheat for 30 sec in the microwave before serving.
