Blend the oats, egg white, and water until the consistency is smooth (I use a Nutribullet)
Pour the mixture into a bowl. 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 plus 1 tsp. Stevia. Pour the remaining batter 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.
This recipe is for one serving of cinnamon swirl cake.This dish keeps very well in the fridge. Store in an airtight container in the refrigerator for 3-4 days.To reheat, place in the microwave for 30 seconds.Make sure you're using a protein powder with a strong vanilla flavor that holds up well to baking. If the recipe doesn't come out right, consider changing the protein powder.
