  • Shortbread Dough:
  • 1 1/2 cup unsalted butter room temperature
  • 2 Tbsp unsalted butter room temperature
  • 1 1/4 cup confectioners sugar
  • 2 extra large egg yolks room temperature
  • 2 tsp vanilla extract
  • 2 1/4 cup all purpose flour
  • 1 cup black cocoa powder sifted
  • 1 tsp kosher salt
  • 1 tsp sea salt flakes
  • Peppermint Buttercream Frosting:
  • 24 peppermint candies pulverized into a powder
  • 1 cup unsalted butter room temperature
  • 4 ounces cream cheese room temperature
  • 1 cup confectioner's sugar
  • 4 ounces white chocolate melted
  • 1 tsp vanilla extract
  • 1/2 tsp kosher salt
  • White Chocolate Peppermint Bark:
  • 36 peppermint candies crushed but with a few small pieces
  • 6 ounces white chocolate melted


  • Make Dough:
  • Add dry ingredients, flour, salt and sifted black cocoa powder to a medium sized
  • bowl. Set aside.
  • In a large mixing bowl, blend butter on medium speed for five to ten seconds. Add sugar and mix on low to incorporatet. Increase speed
  • to medium and cream the butter mixture until it is aerated and looks like frosting, about three minutes.
  • Scrape the sides and bottom of bowl with a spatula to make sure all the ingredients are incorporated.
  • Add the yolks, one at at time.
  • Add the vanilla extract.
  • Mix briefly until the egg yolks combine with the cookie dough. Scrape bowl. Mix another 30 seconds.
  • Add flour mixture all at once and mix on low until the dough just comes together,k about one minute.
  • Use a plastic bench scraper to finish bringing the dough together by hand.
  • Divide dough in half and place each half on a retangle of plastic wrap. Pat each
  • half down and wrap tightly. Chill in refrigerator at least two hours, preferably overnight.
  • When you're ready to bake the shortbread, let the dough sit at room temperature for about 15 to 20 minutes.
  • You want it pliable but still cool to the touch.
  • Place the dough between two sheets of parchment and roll out until you have a rectangle about
  • a 1/4 inch thick or a bit less.
  • Cut into desired shapes with cookie cutter, ideally 1 3/4 by 2 1/2 inch. Bake cookies on parchment lined half sheet pan at 350 for 12 to 15 minutes.
  • Pay attention to smell. When they smell done, they usually are. But pay attention to the timer
  • and their appearance too. My magic number was 13 minutes.
  • Repeat process with second lump of dough.
  • Make peppermint buttercream frosting:
  • Blend peppermints in a food processor until they form a powder. This step is crucial. Sift
  • the powder to make sure you've gotten out all the pieces and chunks. If you don't do this,
  • those little pieces and chunks will clog up your pastry tip when you're frosting the cookies.
  • This happened to me and I had to finish frosting with an offset spatula. Not the worst problem in the world
  • but I didn't get them as neat as I would have liked.
  • Set pulverized peppermints aside.
  • In medium sized bowl or in the bowl of a stand mixer, mix butter briefly for 5 to 10 seconds.
  • Add cream cheese and beat to combine. Add the sugar and beat until the butter mixture is
  • aerated and pale in color, about 3 minutes. Remember to scrape bottom and sides of bowl with
  • a spatula to incorporate everything. Mix in the melted chocolate, vanilla and salt for about
  • one minute. Mix in the ground peppermints. Voila, you've just made peppermint buttercream
  • frosting, which should be a luverly pale pink.
  • Fill a pastry bag with an Ateco tip #804 and fill with frosting. Frost cookies, sandwich together and then refrigerate
  • until bark is ready.
  • Make white chocolate peppermint bark:
  • Line a sheet pan or anything you want to use with parchment--I was out of sheet pans at this point
  • so I used a 9x13 cake pan. Improvise people!
  • Put peppermints in food processor and pulse until you have a blend of fine and small pieces.
  • Pour into a bowl and fold in the white chocolate.
  • Pour the mixture into your prepared pan and spread out, using a spatula, until the mix is
  • about a 1/4 inch thick.
  • Bang pan against a work surface to flatten. Refrigerate or freeze until firm 25 to 30 minutes.
  • Once firm, break into small pieces for affixing to each cookie.
  • To Gild the Lily:
  • Melt bittersweet, semisweet or regular ole' chocolate (I used a big Hershey's bar) in a small
  • bowl. Dip half of each cookie into the melted chocolate and place on parchment paper.
  • Put a piece of bark onto each cookie. Refrigerate until chocolate is firm.
  • The cookies will keep, refrigerated, for one week.
