Place heaping teaspoons of batter onto lightly greased or silicon or parchment-lined baking sheets.
Bake at 350 degrees for approximately 12 minutes or until firm to touch.
After removing from the oven, let stand on baking sheets for about 10 minutes and then move cookies to a cooling rack to cool completely.
