Line a cookie sheet with wax paper or a baking mat. Scoop a little less than ¼ cup of cookie batter on, then flatten into the shape of a cookie. Bake for 15 minutes. You should have 12 cookies.
After 15 minutes, flip the cookies with a spatula and brown the other side for 2-3 minutes.
Let the cookies cool on a baking rack for 5 minutes before enjoying.
