Method
Make the dough
- Preheat the oven to 350°F with racks in the upper and lower thirds.
- Line two large baking sheets with parchment paper.
- Whisk the flour, cream of tartar, baking soda, salt, and 1/4 teaspoon of the nutmeg in a medium bowl.
- Beat the butter and 1 1/2 cups of the sugar in a large bowl until light and fluffy, about 2 minutes.
- Beat in the egg, eggnog, and vanilla.
- Add the flour mixture and mix on low just until combined.
- Cover and refrigerate the dough for 30 minutes.
Mix the coating and shape the cookies
- Stir the remaining 1/4 cup sugar, cinnamon, and remaining 1/4 teaspoon nutmeg in a small bowl.
- Shape the dough into 1 1/2-tablespoon balls.
- Roll each ball in the sugar mixture to coat.
Bake the cookies
- Arrange 12 dough balls on each baking sheet, spacing them about 2 inches apart.
- Bake both sheets for 10 to 12 minutes, swapping their rack positions and rotating them front to back halfway through, until the edges are set and the tops are cracked.
- Let the cookies cool on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool completely.
Notes
For the best texture, refrigerate the dough for the full 30 minutes. Store cookies in an airtight container in the refrigerator for up to 5 days; freeze baked cookies for up to 2 months. For a dairy-free swap, use plant-based butter and eggnog.
