Preheat oven to 350 degrees and line two baking sheets with parchment paper
In a large bowl, mix together your flour, ginger, cinnamon, nutmeg, allspice, baking soda, and salt.
Using another bowl or stand mixer, beat together the brown sugar and butter until light and fluffy. Mix in the molasses, egg, and vanilla extract.
Now, you will add in the dry ingredients gradually until the dough forms.
Pour your sanding sugar into a bowl, and form small balls of cookie dough then roll them in the sanding sugar.
Place the cookie dough balls on the prepared baking sheets, then bake for 8-10 minutes.
Pull from the oven and allow them to cool for 2-3 minutes before adding a Hershey's kiss into the center.
Allow them to cool completely before serving.
