01 - Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease each cup.
02 - In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, salt, ground cinnamon, ground nutmeg, and ground cloves until well blended.
03 - In a large bowl, use an electric mixer or whisk to beat softened butter, granulated sugar, and light brown sugar until pale and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time to the butter mixture, beating thoroughly after each addition. Stir in pure vanilla extract to combine.
05 - Add the dry ingredients to the wet mixture in alternating portions with eggnog, beginning and ending with dry ingredients. Mix gently until just incorporated, taking care not to overwork the batter.
06 - Evenly distribute the batter among the prepared muffin cups, filling each approximately three-quarters full.
07 - In a small bowl, combine crushed holiday cookies, melted butter, granulated sugar, and ground cinnamon. Sprinkle the mixture generously over each muffin.
08 - Bake muffins for 20 to 22 minutes, or until a toothpick inserted in the center comes out clean.
09 - Allow muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
10 - In a small bowl, whisk together powdered sugar and eggnog until smooth. Drizzle glaze over cooled muffins as desired.
