Method
Make the dough
- Whisk the flour, cream of tartar, baking soda, and salt in a medium bowl.
- Set aside 1/4 cup of the granulated sugar for the coating.
- In a large bowl, beat the butter with the remaining 1 1/2 cups sugar on medium speed until light and fluffy, 2 to 3 minutes.
- Beat in the egg, eggnog, and vanilla until combined.
- Mix in the flour mixture on low just until no dry streaks remain.
- Cover and refrigerate the dough for 30 minutes.
Coat and bake
- Heat the oven to 350°F with racks in the upper and lower thirds, and line two large baking sheets with parchment paper.
- Stir the reserved sugar, cinnamon, and nutmeg together in a shallow bowl.
- Roll the dough into 2-tablespoon balls and coat each in the sugar mixture.
- Arrange 12 balls on each baking sheet, spacing them about 2 inches apart.
- Bake both sheets for 10 to 12 minutes, switching their positions and rotating them halfway through, until the edges are set and the centers look puffed and slightly soft.
- Cool the cookies on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool.
Notes
For tender cookies, mix the flour in just until no dry streaks remain. Store in an airtight container at room temperature for up to 4 days; freeze baked cookies for up to 3 months. For a dairy-free option, use dairy-free butter and dairy-free eggnog.
