Place flour, baking soda, baking powder, nutmeg, salt, and cream of tartar to large bowl. Mix well, and set aside.
Place butter and vanilla extract in a bowl, and beat well with mixer until creamy.
Add granulated sweeteners and beat until well-blended and fluffy.
Add egg (or egg alternatives) and eggnog and mix well.
Add dry ingredients to wet ingredients and stir until just combined. Be careful to not over mix. Try not to eat too much dough--it's hard, but you can do it!
If you will be baking with parchment paper, cover your cookie sheet with the paper now.
Using a spoon or cookie scoop, scoop out uniform, small (approximately 1-inch) balls, and place on a plate. But no need to be too perfectionistic about it--they're just cookies! And have fun doing this--aren't scoops fun?
Roll each cookie dough ball in the Spice Topping Blend to coat. Place on cookie sheet.
Place cooking sheet into the refrigerator 30 minutes to least 1 hour to chill to prevent spreading (optional).
About 10 minutes before baking, preheat oven to 325 degrees. Remove cookies from fridge, space cookies about 2 inches apart on the cookie sheet.
Press down the cookies slightly to allow them to spread out a bit.
Bake 8-10 minutes or until lightly browned.
Allow 5-10 minutes for cookies to cool completely before removing them from the baking sheet. Note: this is VERY important for gluten-free and grain-free baking.
Make the glaze while the cookies are cooling. Try not to lick the spoon (too many times).
Drizzle with glaze when the cookies have completely cooled.
