Whisk flour, baking soda, salt and spices in a bowl.
In a large mixing bowl, beat butter and sugars with an electric mixer until creamy. Mix in egg and molasses.
Add dry ingredients and mix until soft cookie dough forms.
Cover cookie dough with plastic and chill in the refrigerator for 1-2 hours (can chill longer if needed).
Preheat the oven to 350 degrees and line a baking sheet with parchment paper.
Scoop dough using a medium cookie scoop (2 Tbsp.) then roll in granulated sugar.
Bake the cookies, 6 per cookie sheet* for 12-13 minutes. Let cookies stand for 5-7 minutes before transferring to a wire cooling rack.*Cookies will spread so only bake 6-9 at a time. You can keep the rest of the dough in the refrigerator while you wait to bake it.

Notes
This recipe makes about 2 dozen cookies.I bake with light baking sheets so my recipe times reflect that. If your cookie sheets are dark may need to adjust the baking time, baking the cookies for less time.
