Preheat oven to 350°F.
Whisk together flour, sea salt, cinnamon, pumpkin spice, and baking soda to combine. Set aside.
Whisk together in separate bowl the melted butter, sugar, brown sugar, vanilla, egg and molasses until combined
Stir the dry ingredients into the wet ingredient, only until combined.
Chill for about 20 minutes or until you can easily roll into balls.
On a parchment lined baking sheet, roll dough into one inch balls. If desired, press a pecan into the cookies if not icing. If not, leave them as is for baking. Place the cookies about 2 inches apart.
Bake for 8-10 minutes or until edges are just barely browned--they may not seem like they are done, but grab them just before you think they are done.
