Cream shortening with 1 cup of sugar. (reserve ½ cup of sugar for rolling formed cookies in step #7)
Stir in molasses and beaten egg.
Add remaining ingredients, except gluten-free flour and ½ cup sugar, and blend well.
Add gluten-free flour and mix. If using a stand or hand mixer, mix the dough for an additional 2-3 minutes after the ingredients are fully mixed for the best results.
Chill dough in the refrigerator for one hour.
Preheat oven to 350℉. Prepare baking sheets with parchment paper or silicone baking mats.
Place the remaining ½ cup of sugar in a small bowl. Shape dough into 1-inch balls, about the size of a walnut in its shell. Roll in the sugar to coat.
Place on prepared baking sheets and bake in the preheated oven for 10-12 minutes. Let rest on baking sheet for 2-3 minutes before transferring to cooling racks.
