Noël Nut Balls

In large bowl, with mixer on medium-high speed, beat butter and honey until fluffy. Add bourbon and beat until combined. In medium bowl, with wire whisk, mix together flour, walnuts, confectioners' sugar, and salt. Add to butter mixture, and beat until combined. Gather dough and flatten into a disk. Wrap in plastic wrap and refrigerate 3 hours. Preheat oven to 350 degrees F. Line 2 large cookie sheets with parchment paper or Silpats (French nonstick baking mats). Roll dough, 2 teaspoons at a time, into balls. Place, 2 inches apart, on prepared cookie sheets. Bake until browned around edges, 12 to 13 minutes. Transfer to wire racks to cool completely. Roll in confectioners' sugar to coat. Store in airtight container at room temperature up to 5 days.
