Preheat your oven to 325. Prep a sheet with parchment paper.
In a bowl, beat together the egg whites and creme of tarter. You should see peaks form.
In a separate bowl, mix together your dairy, sugar alternative, and egg yolks. You will need to mix this until smooth. Sometimes using a whisk after using a spoon with help you get it smooth enough to move on. Once smooth you can gently stir in any optional ingredients.
Now, fold the egg white and tarter mixture into the contents of the second bowl. Do this gently to insure that your egg whites stay peaked.
Use a scoop or large spoon to scoop the batter on to the baking sheets. This will spread to about 4".
Bake for 30 minutes or until these begin to brown. Remove from oven and allow to cool on the pans for five minutes and then transfer to a rack to finish cooling.
