Preheat oven to 350 degrees and line cookie sheets by lining with parchment paper.

Scoop about 2-2 1/2 Tablespoons of cookie dough and roll into balls, making them slightly taller than they are wide. Place them at least 2 inches apart on prepared cookie sheet.

Bake at 375 degrees for about 13 minutes (cookies will appear to be a bit underdone, but edges should be just beginning to turn golden brown).

Allow cookies to cool completely on cookie sheet. Makes 1 1/2 dozen cookies.
