Ingredients

Scale

Eggnog Cookies

  • 2 1/2 cups all-purpose flour (313 grams)
  • 1 teaspoon nutmeg
  • 1/2 teaspoon cinnamon
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3/4 cup unsalted butter (168 grams), softened to room temperature
  • 3/4 cup granulated sugar (150 grams)
  • 1/4 cup brown sugar (50 grams), light or dark
  • 2 large egg yolks (discard the whites)
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon rum extract (use up to 1 teaspoon if desired)
  • 1/3 cup eggnog (80 ml)

Eggnog Frosting

  • 2/3 cup unsalted butter (151 grams), salted butter works too (omit salt from recipe if using salted)
  • 34 cups powdered sugar (330440 grams)
  • 1/4 teaspoon nutmeg
  • 1/2 teaspoon rum extract
  • 1/4 teaspoon salt
  • 35 tablespoons eggnog (4575 ml)
  • 12 tablespoons cornstarch (cornflour), optional, for thickening

Instructions

  1. Preheat Oven and Prepare Baking Sheets: Preheat your oven to 350°F (180°C) or 325°F (170°C) if using a convection oven. Line cookie sheets with parchment paper or silicone baking mats to prevent sticking and facilitate even baking.
  2. Mix Dry Ingredients: In a medium-sized bowl, whisk together the all-purpose flour, nutmeg, cinnamon, baking soda, and salt. Set aside this dry mixture for later use.
  3. Cream Butter and Sugars: In a large bowl, beat the softened unsalted butter, granulated sugar, and brown sugar together until the mixture is fluffy and light, ensuring good incorporation of air for soft cookies.
  4. Add Egg Yolks and Extracts: Beat in the two egg yolks, vanilla extract, and rum extract into the butter and sugar mixture until fully combined, adding flavor and richness.
  5. Incorporate Eggnog: With the mixer on low speed, gradually beat in the eggnog to the butter mixture, maintaining a smooth consistency without overmixing.
  6. Combine Dry Ingredients with Wet: Slowly add the flour mixture to the wet ingredients, starting the mixer on a low speed and increasing to medium until just combined, avoiding overmixing to keep cookies tender.
  7. Form Cookie Dough Balls: Using a medium cookie scoop or spoon, portion out 1 to 1.5 tablespoons of dough per cookie. Roll each portion into a ball and place them about 2 inches apart on the prepared cookie sheets. For slightly flatter cookies, gently press down on each dough ball.
  8. Bake the Cookies: Bake one sheet at a time on the middle rack of the preheated oven for 8 to 11 minutes or until the cookie tops look set and the edges begin to turn golden. Baking times may vary slightly by oven.
  9. Cool Cookies: Remove the cookie sheet from the oven and allow the cookies to cool on the sheet for at least 10 minutes to firm up before transferring them to a wire rack to cool completely.
  10. Prepare Eggnog Frosting: In a large bowl, beat the 2/3 cup unsalted butter until smooth and creamy. Turn off the mixer, then add 2 cups of powdered sugar along with nutmeg, salt, and rum extract. Gradually beat starting at low speed and increase until well combined.
  11. Finish Frosting: Beat in the remaining powdered sugar ½ cup at a time, alternating with 1 tablespoon of eggnog, until the frosting reaches your desired flavor and consistency. If the frosting is too thin but becomes too sweet when adding sugar, sift and beat in 1 to 2 tablespoons of cornstarch to thicken.
  12. Frost Cookies: Once cookies are completely cooled, use a flat knife or spatula to spread the eggnog frosting evenly over each cookie. Optionally, sprinkle a pinch of nutmeg or cinnamon on top for garnish and extra holiday flair.

Notes

  • Use only egg yolks for the dough; egg whites are not needed and should be discarded or saved for another use.
  • You can adjust the amount of rum extract to your taste; 1 teaspoon provides a stronger flavor.
  • For a gluten-free version, substitute the all-purpose flour with an equal amount of gluten-free flour blend.
  • If you use salted butter in the frosting, omit the added salt to avoid excessive saltiness.
  • Letting cookies cool on the baking sheet before moving prevents them from breaking apart.
  • The cornstarch in the frosting helps if the frosting becomes too thin but adding sugar further isn’t desirable.
  • Store cookies in an airtight container at room temperature for up to 5 days or freeze the dough for future baking.
