Ingredients

Scale

Dry Ingredients

  • 2 and 3/4 cup all-purpose flour (spooned and leveled)
  • 2 teaspoons ground ginger
  • 1 teaspoon cinnamon
  • 1/4 teaspoon ground cloves
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt

Wet Ingredients

  • 3/4 cup unsalted butter (softened to room temperature)
  • 3/4 cup brown sugar (packed)
  • 1 large egg (room temperature)
  • 1 large egg yolk (room temperature)
  • 2 teaspoons vanilla extract
  • 1/3 cup molasses (not blackstrap)

For Coating and Frosting

  • 1/3 cup turbinado or granulated sugar (for rolling dough)
  • 6 tablespoons unsalted butter (softened to room temperature, for frosting)
  • 23 cups icing sugar (sifted, for frosting)
  • 34 tablespoons eggnog (for frosting)
  • 1/4 teaspoon rum extract (optional, for frosting)

Instructions

  1. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, ground ginger, cinnamon, nutmeg, cloves, baking soda, and salt until well combined. Set this mixture aside for later use.
  2. Cream Butter and Sugar: In a separate large bowl, use an electric mixer on medium speed to beat the unsalted butter and brown sugar together until smooth and no lumps remain. This process ensures a creamy base for your cookie dough.
  3. Add Wet Ingredients: Beat in the egg, egg yolk, vanilla extract, and molasses to the butter and sugar mixture until everything is fully incorporated, creating a rich and flavorful dough.
  4. Combine Dry and Wet Mixtures: Reduce the mixer speed to low and slowly add the flour mixture to the wet ingredients. Beat until just combined to avoid overworking the dough. Stop the mixer and scrape down the sides with a spatula if necessary to ensure even mixing.
  5. Chill the Dough: Cover the bowl with cling wrap and refrigerate the dough for at least 30 minutes and up to 24 hours. Chilling helps to develop the flavors and makes the dough easier to handle.
  6. Preheat Oven and Prepare Baking Sheets: When ready to bake, preheat your oven to 350°F (175°C). Line two cookie sheets with parchment paper or silicone baking mats to prevent sticking.
  7. Form and Sugar Coat Cookies: If dough has chilled longer than 2 hours, let it sit at room temperature for about 20 minutes to soften slightly. Using a cookie scoop or spoon, form the dough into balls approximately 1.5 tablespoons in size. Roll each dough ball in turbinado or granulated sugar to coat thoroughly.
  8. Arrange and Bake: Place the sugar-coated dough balls about 2 inches apart on the prepared cookie sheets. Bake in the preheated oven for 8 to 10 minutes or until the cookie tops are just set and edges are firm.
  9. Cool Cookies: Remove the cookies from the oven and allow them to cool on the baking sheets for 5 to 10 minutes before transferring them to a wire rack to cool completely. This prevents breakage and maintains texture.
  10. Prepare Eggnog Frosting: In a medium bowl, beat the softened butter at medium speed until creamy. Gradually add the sifted icing sugar, about 1/2 cup at a time, beating well after each addition until about 2 cups have been incorporated. Add the eggnog one tablespoon at a time and mix until smooth and spreadable. Incorporate the optional rum extract if desired. Adjust the consistency with extra powdered sugar or eggnog as needed.
  11. Assemble Sandwich Cookies: Once the cookies are fully cooled, spread approximately 1 tablespoon of eggnog frosting on the bottom side of one cookie. Top it with a second cookie to create a sandwich. Repeat until all cookies are paired, yielding about 16 to 18 sandwich cookies total.

Notes

  • Allow dough to chill for at least 30 minutes; chilling longer improves flavor and handling.
  • If chilled dough is too firm, let it sit at room temperature for 20 minutes before scooping.
  • Use turbinado sugar for a subtle crunch and decorative sparkle on the cookies.
  • Adjust the eggnog frosting consistency to your preference by adding more powdered sugar for thicker frosting or more eggnog for a thinner spread.
  • Optional rum extract adds a traditional holiday flavor but can be omitted for a non-alcoholic version.
  • Store sandwich cookies in an airtight container at room temperature for up to 5 days or refrigerate for longer freshness.
