Put a small walnut-size ball of batter on a lightly greased cookie sheet. Cover with a square of wax paper and press with the flat bottom of a glass until very flat and thin. Bake for 5 minutes. Cookies will be light brown when done. Remove from cookie sheet with a spatula and let cool on wax paper.
