In a large bowl whisk together flour, baking soda, and spices.
In a mixer cream the butter and brown sugar. Add the egg, vanilla, molasses, orange zest, and bourbon and continue mixing until combined.
Slowly add the dry ingredients to the mixer about a ¼ at a time until incorporated.
Cover the dough and refrigerate for about 30 minutes.
Preheat oven to 350°
Add the sugar to a small plate or bowl.
Take about 1-2 tablespoons of the dough, roll into a ball, then roll in the sugar to coat. Continue to create the sugar coated dough balls and place on a cookie sheet about 2 in apart.
Bake for 8-10 minutes.
