Soft eggnog cookies with warm nutmeg and a creamy eggnog frosting. These cookies bake up tender and lightly spiced, making them a simple holiday treat.
If your dough feels very soft, chill it for 15 minutes before scooping. This helps the cookies hold a neat round shape. Do not overbake these cookies. They should look set on top with only light color at the edges so they stay tender. If the frosting seems too thick, beat in 1 teaspoon of eggnog at a time. If it seems too loose, add 1 tablespoon of powdered sugar at a time until spreadable. Store the frosted cookies in an airtight container in the refrigerator for up to 4 days. Let them sit at room temperature for 15 to 20 minutes before serving so the frosting softens slightly. To freeze, place unfrosted cookies in an airtight container and freeze for up to 2 months. Thaw at room temperature, then frost before serving.
