Ingredients

Scale

For the Cookies

  • 1 ¼ cups (2 ½ sticks) unsalted butter, softened to room temperature
  • 1 cup packed light brown sugar
  • 4 large egg yolks
  • ¼ cup eggnog
  • 1 tablespoon spiced rum (or 1 teaspoon rum extract)
  • 3 cups all-purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • ½ teaspoon freshly grated nutmeg
  • ½ teaspoon ground cinnamon
  • A small pinch of allspice

For the Frosting

  • 6 tablespoons unsalted butter, softened
  • 2 ¼ cups powdered sugar
  • 1 ½ teaspoons spiced rum (or ¼ teaspoon rum extract)
  • 2 tablespoons eggnog
  • ¼ teaspoon freshly grated nutmeg
  • A pinch of cinnamon

For Decorating

  • Extra flour (for rolling out dough)
  • Festive sprinkles of your choice


Instructions

Make the Cookie Dough

  1. Cream the butter: In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium speed until smooth and pale, about 2 minutes.

  2. Add sugar: Pour in the brown sugar and continue beating for another minute until fluffy and light.

  3. Mix in wet ingredients: Reduce the speed to low and add the egg yolks one at a time. Then pour in the eggnog and rum (or extract) and mix just until everything is combined.

  4. Combine dry ingredients: In a separate bowl, whisk together the flour, baking powder, salt, nutmeg, cinnamon, and allspice.

  5. Bring the dough together: Gradually add the dry mixture to the wet ingredients while mixing on low speed. Mix until a soft dough forms. Scrape the bowl and mix briefly again to ensure everything is incorporated.

  6. Chill: Divide the dough in half, flatten each piece into a disc, wrap tightly in plastic wrap, and refrigerate for about 2 hours or until firm enough to roll.


Make the Frosting

  1. Beat the butter: In a clean mixing bowl, beat butter until smooth and creamy.

  2. Add sugar and flavorings: Gradually mix in powdered sugar. Then add rum (or rum extract), eggnog, nutmeg, and cinnamon.

  3. Whip until smooth: Beat for 2–3 minutes until light and fluffy. If the frosting seems too thick, add a teaspoon of milk or more eggnog until you reach a spreadable consistency.

  4. Set aside: Keep the frosting at room temperature while baking the cookies.


Bake the Cookies

  1. Preheat oven: Set your oven to 325°F (163°C) and position the rack in the upper third. Line baking sheets with parchment paper.

  2. Roll the dough: Lightly flour your counter. Place half the chilled dough on the surface and roll to about ¼ inch thick.

  3. Cut shapes: Use your favorite cookie cutters (stars, trees, bells—whatever screams “holidays!”) and transfer shapes to the prepared baking sheets. The cookies spread very little, so you can space them about ½ inch apart.

  4. Bake: Bake one sheet at a time for 12 minutes, or until the bottoms are golden and the tops are just turning a pale tan.

  5. Repeat: Gather and re-roll the dough scraps as needed—you can reuse them several times without affecting texture.

  6. Cool: Let the cookies rest on the baking sheet for a few minutes, then move them to a wire rack to cool completely.


Frost and Decorate

 

  1. Once cookies are completely cool, spread or pipe the frosting generously on top.

  2. If the frosting stiffens while you work, whisk in a touch of milk or eggnog to loosen it up.

  3. Before the frosting sets, shower each cookie with colorful holiday sprinkles.

  4. Allow frosting to firm up before stacking or storing.


Notes

  • Storage Tips
    • Room temperature: Keep in an airtight container for up to 3 days.
    • Refrigerated: Store up to 5 days if your kitchen runs warm. Bring to room temp before serving.
    • Freezer-friendly: Freeze unfrosted cookies for up to 3 months; thaw and frost later for fresh holiday flavor.
  • Baker’s Notes
    • Freshly grated nutmeg makes all the difference—trust me.
    • Don’t skip chilling the dough! It helps your cookies keep their shape.
    • These cookies are rich but not overly sweet, so the frosting shines without being cloying.
