Measure dough, form, and roll in sugar.

Scoop a heaping tablespoon of cookie dough and roll it into a ball. Then, roll it in granulated sugar. (We like to use a small cookie scoop to make the cookies as even in size as possible.)

Forming Cookie Balls and Rolling in Sugar

Note: When you first mix the dough, you may think there is no way to roll it into balls, but it rolls easily, even if it looks too sticky!


Place on baking sheet.

Arrange the sugared cookie dough balls on a prepared baking sheet. Leave room between the cookies to press them down in the next step.
