In a large bowl with an electric hand mixer or the bowl of a stand mixer fitted with a paddle attachment, cream room temperature unsalted butter and brown sugar.
Add egg, vanilla extract, and molasses and mix until smooth.
Add in the dry ingredients (spices, baking soda, salt, and all-purpose flour) and mix on low speed until a soft dough forms.
Portion the cookie dough using a small cookie scoop. Place the dough balls on a baking sheet pan and chill for 30 minutes.
Preheat oven to 350° F and prepare baking sheet pans with a silicone baking mat or parchment paper.
In a small bowl, combine granulated sugar and cinnamon. Roll the chilled cookie dough balls in cinnamon sugar and place on the baking pan allowing room for spreading.
Bake for approximately 8-10 minutes until the cookies are slightly golden-brown on the edges. Cool the cookies on the pan for 2 minutes before transferring to a wire rack to cool completely.
