01 - Preheat oven to 350°F and line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a medium mixing bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and cloves until evenly blended.
03 - In a large bowl, beat softened butter, granulated sugar, and brown sugar with an electric mixer until pale and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time, mixing well after each. Blend in vanilla extract until fully incorporated.
05 - Alternately add dry ingredients and eggnog into the butter mixture, beginning and ending with dry ingredients. Stir just until combined; avoid overmixing.
06 - Divide the batter evenly among muffin cups, filling each about three-quarters full.
07 - Stir together crushed cookies, melted butter, granulated sugar, and cinnamon in a small bowl. Sprinkle the mixture over each muffin.
08 - Bake for 20 to 22 minutes, or until a toothpick inserted in the center emerges clean.
09 - Allow the baked muffins to rest in the tin for 5 minutes, then transfer to a wire rack to cool completely.
10 - Whisk together powdered sugar and eggnog until smooth; drizzle over cooled muffins if desired.
