  • Preheat the oven to 325 F (165 C)
  • 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.
