5 eggs, separated 1 cup vanilla whey protein or egg white protein 4-8 tablespoons of cinnamon (depends on how much you like cinnamon!) Preheat the oven to 375 degrees. Separate the eggs and whip the whites until very stiff. Slowly add in the whey protein. Blend until smooth and then very gently add in the yolks (try to keep the whites fluffy).Grease a bread pan and pour the mixture into the pan. Bake at 375 degrees for 45 minutes. Turn off the oven and leave the bread in to cool slowly. After an hour, take the bread out. Once totally cool, cut into 12 large slices. I love mine toasted with cream cheese! It also makes great French toast.
