Preheat oven to 325F (163C).
Mix all cookie ingredients until well combined. If you need more water, add it by the ¼ teaspoon.
Spoon cookie batter onto a parchment-lined cookie sheet (1 large or 4 small cookies) and use your spoon to shape them into circles.
Bake for 5 minutes, and check to see if they are firm. If not, check every minute. Be sure not to over-bake these cookies! Take them out as soon as they are firm.
Let cool.
Put the unflavored and chocolate whey proteins in separate bowls.
Add 1½ packets stevia to the unflavored, and ½ packet to the chocolate.
Add 2 teaspoons filtered water to each. Mix well.
If either icing is not a spreadable consistency, add more water by the ¼ teaspoon.
Turn the cookies over, as you'll want to ice the bottom (flat side) of each cookie.
Ice half of each cookie with the white icing, and the other half with the chocolate.
Enjoy! Store in the refrigerator.
