Eggnog Cookies

1. Line a cookie sheet with parchment paper.
2. In a medium bowl, mix together the flour, baking powder, nutmeg and cinnamon. Set aside.
3. In a large bowl, cream the butter and sugar. Add the egg yolks and vanilla to the mixture and beat until smooth. Add eggnog and mix on medium speed until smooth and creamy. Slowly add the flour mixture into the eggnog mixture and stir until well combined. Chill dough in the refrigerator for 20 minutes.
4. Preheat the oven to 350ºF. Using a cookie scoop or spoon, drop spoonfuls of dough onto the cookie sheet about 1 inch apart. Bake for 15-20 minutes or until bottoms are lightly browned. Transfer the cookies to a cooling rack.
5. Make the icing: In a small bowl, whisk the powdered sugar and eggnog together. Add more sugar or eggnog, depending on the consistency you prefer.
6. Drizzle the icing on cooled cookies and sprinkle with nutmeg. Store in an airtight container in the refrigerator.
