Whisk the flour, baking soda, spices, and salt together in a bowl.
In a stand mixer, cream together the butter and sugars until quite fluffy. Then add the egg and molasses and mix until homogenous, scraping the bottom of the bowl with a spatula halfway through.
Add the dry ingredients to the mixer and mix until just combined.
Put the sanding or raw sugar in a bowl. using a small cookie scoop or tablespoon, scoop the dough out one cookie at a time. Roll each into a ball and roll to coat in the sugar.
Put the cookies on parchment-lined baking sheets with room to expand.
Bake the sheets of cookies in the oven for 8 minutes, then check their doneness with your Thermapen ONE. Look for a temperature no lower than 185°F (85°C). If you've got it, take them out; if not, keep cooking for another couple minutes and check doneness again.
Transfer the cookies to a cooling rack and try to restrain yourself for juuuust a minute or two before you dive in!
