Ingredients

Scale

Cookie Bars

  • 1/2 cup butter (salted or unsalted), softened
  • 3/4 cup granulated sugar
  • 1/4 cup brown sugar
  • 1 egg
  • 1/3 cup eggnog
  • 1 teaspoon vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon nutmeg
  • 1/2 teaspoon salt

Frosting

  • 1/4 cup butter (salted or unsalted), softened
  • 2 cups powdered sugar
  • 1/4 cup eggnog
  • 1/2 teaspoon vanilla extract
  • A pinch of nutmeg for garnish

Instructions

  1. Prepare the Cookie Dough: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This creates a smooth base for the cookie dough.
  2. Add Wet Ingredients: Beat in the egg, eggnog, and vanilla extract until fully incorporated, ensuring the mixture is uniform and smooth.
  3. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, nutmeg, and salt to evenly distribute the leavening and spices.
  4. Mix Dry and Wet Ingredients: Gradually add the dry ingredients into the wet ingredients, mixing until just combined to form a dough. Avoid overmixing to keep the bars tender.
  5. Prepare Baking Pan: Grease or line a 9×13-inch baking pan with parchment paper for easy removal and even baking. Spread the dough evenly into the pan.
  6. Bake the Bars: Preheat the oven to 350°F (175°C) and bake the cookie bars for 20-25 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean.
  7. Cool Completely: Allow the bars to cool completely in the pan on a wire rack before frosting, preventing the frosting from melting.
  8. Make the Frosting: In a medium bowl, beat the softened butter until creamy. Gradually add powdered sugar, eggnog, and vanilla extract, beating until smooth and spreadable.
  9. Frost the Bars: Spread the eggnog frosting evenly over the cooled cookie bars. Sprinkle a pinch of nutmeg on top for a festive garnish.
  10. Serve and Store: Cut the bars into squares and serve. Store any leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.

Notes

  • For a stronger eggnog flavor, you can add an extra tablespoon of eggnog to the dough or frosting.
  • Use fresh nutmeg for the best aroma and flavor.
  • These bars can be made ahead and refrigerated; just bring to room temperature before serving for the best texture.
  • If you want a non-alcoholic version, use regular eggnog without alcohol.
  • Ensure the cookie bars are completely cooled before frosting to prevent melting or sliding.
