Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, ground cinnamon, and nutmeg. Set aside.
In a large mixing bowl, cream together the softened butter and granulated sugar using an electric mixer until light and fluffy (about 3 minutes).
Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract and eggnog until well combined.
Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix.
Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheets, spacing them about 2 inches apart.
In a small bowl, combine the powdered sugar and a pinch of cinnamon. Roll each cookie ball in this mixture until fully coated.
Bake for 10-12 minutes or until the edges are lightly golden and the centers appear just set. Let them cool on the baking sheets for 5 minutes before transferring to wire racks to cool completely.
For an extra touch, drizzle with a simple glaze made from powdered sugar and a splash of eggnog before serving.
