Preheat oven to 350 degrees.

In a stand mixer beat butter, stevia, egg and vanilla extract on medium speed 3 for about 2-3 minutes.

Mix in flour, cream of tartar, baking soda and salt until blended.

Add in cinnamon, nutmeg, ginger and molasses scraping down the sides of the bowl between mixing as needed.

Stir in optional chocolate chips if using.

Chill for about 30 minutes in refrigerator if the batter is too soft to roll into balls.

Roll into 1 inch balls and place on a parchment lined baking sheet.

If using coating, mix ingredients together in a small bowl and roll each ball in coating.

Bake 8-10 minutes.

Cool for a minute on pan then remove to a wire rack to finish cooling.
