01 -  Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease each cup. 
 02 -  In a medium mixing bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and cloves. 
 03 -  In a large bowl, beat softened butter with granulated and brown sugars until light and fluffy using an electric mixer, about 2 to 3 minutes. 
 04 -  Add eggs one at a time, blending well after each addition. Stir in vanilla extract until combined. 
 05 -  Gradually add dry mixture to wet ingredients, alternating with eggnog and beginning and ending with dry ingredients. Mix until just incorporated; do not overmix. 
 06 -  Divide batter evenly among prepared muffin cups, filling each about three-quarters full. 
 07 -  For the topping, combine crushed holiday cookies, melted butter, granulated sugar, and cinnamon in a small bowl. Sprinkle mixture over each muffin before baking. 
 08 -  Bake for 20 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean. 
 09 -  Let muffins cool in tin for 5 minutes, then transfer to a wire rack to cool completely. 
 10 -  To make the glaze, whisk powdered sugar with 1 to 2 tablespoons eggnog until smooth. Drizzle over cooled muffins if desired.
