To Bake the Cookies
Preheat oven to 325°F and line two baking sheets with non-stick silicone mats or parchment paper.
Pour the 1⁄4 cup of granulated sugar into a small bowl.
Remove the dough from the refrigerator and discard plastic wrap. Divide dough into balls about 1 1/2 inch in size. You should have about 2 dozen.
Roll each ball in the granulated sugar until coated.
Place dough balls on prepped cookie sheet, about an inch apart. Bake at 325°F for 10-13 minutes, until the edges of the cookies just start to crack. Move to wire rack to cool.
