  • Use your hands to form 20-24 even sized dough balls. Place the balls two inches apart on a large cookie sheet or two smaller ones lined with parchment paper. Bake for 10-12 minutes.
  • Meanwhile, start the filling by beating the ½ cup unsalted butter in an electric mixer on medium speed for about 2 minutes. Add the 2 tbsp eggnog and 2 tbsp heavy cream and beat for another 2 minutes until smooth. Keep your eye on this mixture because it can seize up quickly.

  • When the cookies are done, let them cool at room temperature for at least 30 minutes or until they are no longer warm to the touch.
  • Fill a piping bag fitted with a 1 inch tip with the filling. Pipe about 2 tbsp of filling onto half of the cookies in a circular motion. Sandwich each with a corresponding bare cookie, slightly pressing down until the filling fills the the edge.
