Preheat oven to 375 degrees. In a mixing bowl, combine flour, baking soda, spices, and salt and whisk well to incorporate the ingredients evenly. Set aside.
Using a stand mixer, cream butter for 1 minute until creamy and fluffy. Scrape down the sides of the bowl using a spatula. Add sugars and mix on medium speed for an additional minute.
Add egg, molasses, and vanilla to the butter mixture and beat until smooth and ingredients are well incorporated.
Add flour mixture and stir on low speed stopping once dough is evenly combined.
In a small bowl combine coarse sugar and remaining spices.
Using a medium sized ice cream scoop, scoop dough and form into balls using the palms of your hands. Roll in spiced sugar mixture and arrange evenly on an ungreased cookie sheet.
Bake for 9-11 minutes. Remove from pan immediately and let cool on a rack.
