Cover the cookie dough with plastic wrap and refrigerate for at least 3 hours. Preheat the oven to 350°F (180°C). Line three baking sheets with parchment paper and set aside.
Roll heaping tablespoons of dough into balls, then place into the granulated sugar and roll to coat. Transfer to the powdered sugar and roll to coat completely.
Bake in the preheated oven for 8-10 minutes, or until the cookies have puffed and crackled. Allow to cool 10 minutes before transferring to a wire cooling rack to cool completely.
