01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and cloves.
03 - In a large bowl, beat softened butter with granulated sugar and brown sugar until light and airy, approximately 2 to 3 minutes using an electric mixer.
04 - Add eggs individually, mixing thoroughly after each addition. Stir in vanilla extract until evenly blended.
05 - Gradually add dry ingredients to the butter mixture, alternating with eggnog. Begin and finish with dry ingredients. Mix gently until just combined; avoid overmixing.
06 - Divide batter equally among prepared muffin cups, filling each about three-quarters full.
07 - In a small bowl, blend crushed holiday cookies, melted butter, sugar, and ground cinnamon. Sprinkle topping over unbaked muffins.
08 - Bake in preheated oven for 20 to 22 minutes, or until a toothpick inserted in the center emerges clean.
09 - Let muffins rest in the tin for 5 minutes before transferring to a wire rack to cool completely.
10 - Combine powdered sugar and eggnog, whisking until smooth. Drizzle glaze over cooled muffins.
