Ingredients

  • 1 cup unsalted butter softened
  • 4 cups powdered sugar
  • ¼ cup eggnog
  • ½ teaspoon ground nutmeg
  • ¼ teaspoon rum extract
  • teaspoon salt

Instructions

  • Using a stand mixer with the whisk attachment, beat the butter until it turns white and creamy, about 3-4 minutes.
  • Turn the mixer to low speed and add the powdered sugar, along with the nutmeg and rum extract, then increase speed to medium-high and beat until smooth. 
  • Add the eggnog and continue to beat until the consistency is smooth and pipeable, about 3-4 minutes.
  • Fill into a piping bag and use right away or store in an airtight container at room temperature for 1-2 days.

Notes

  • Make sure the butter is softened to room temperature, you should be able to make a dent by pressing in with your thumb
  • Add additional eggnog as needed to get a smooth buttercream consistency
  • Instead of eggnog, you can also use cream, add some additional nutmeg and rum extract to boost the flavor
  • This recipe works great for frosting cupcakes, cakes, and cookies
  • Don't skip the nutmeg and rum extract, they are the secret to making the frosting taste like eggnog
  • You can replace the rum extract with vanilla extract if you prefer
  • To replace the rum extract with rum you need to use 2-3 tsp of rum, you might want to reduce the amount of eggnog or the frosting might get too thin
  • This recipe can be doubled or tripled if you have a bowl that’s large enough
