1. Place all ingredients, except 1/4 cup sugar, in the bowl fitted with the kneading/crushing blade. Mix at speed 8 for 2 minutes 30 seconds. Form the dough into a ball and wrap in plastic wrap. Refrigerate for 2 hours.
2. Preheat the oven to 300°F.
3. Form the dough into 1 Tbsp. size balls. Roll the balls in remaining 1/4 cup sugar and place on a cookie sheet lined with parchment paper. Flatten slightly with the bottom of a glass.
4. Bake for 12-14 minutes or until set. Cookies should be soft at the end of baking; they will become crisp as they cool.
