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!
