- Preheat the oven to 325 degrees. 
- Separate the eggs. Place the whites and the salt into a stand mixer (or large bowl) whip the whites until very stiff. 
- Slowly add in the protein powder. Do not over mix, otherwise it will turn out like styrofoam. 
- Blend until smooth and then very gently add in the yolks OR the cream cheese (try to keep the whites fluffy). Omit for protein sparing. 
- Next swirl in the cinnamon. 
- Grease a bread pan and pour the mixture into the pan. 
- Bake for 20-25 minutes. Turn off the oven and leave the bread in to cool slowly. 
- After 20 minutes, take the bread out. 
- Once totally cool, cut into 12 large slices. I love mine made into French Toast!
