Shortbread has always been my favorite Christmas cookie for as long as I can remember. However the last few years I have been experimenting with different flavors of shortbread. None of them will ever replace the plain traditional shortbread that I love, but this one is definitely worth making. It combines my love of shortbread, coffee and toffee.
Espresso Chocolate Toffee Shortbread
Ingredients:
- 1 tablespoon instant espresso powder
 - 1 tablespoon boiling water
 - 2 sticks (16 tablespoons) unsalted butter, room temperature
 - 2/3 cup confectioners' sugar, plus extra for dusting
 - 1/2 teaspoon vanilla extract
 - 4 ounces heath bar, finely chopped
 
Directions:
- In a small bowl dissolve the espresso powder in the boiling water.
 - In a large bowl, with an electric mixer, combine the butter and confectioners' sugar for 3 minutes at medium speed.
 - Add in the vanilla and espresso, beat just until incorporated.
 - Add in the flour and mix at low speed just until combined.
 - Fold in the chopped heath bar.
 - Transfer dough to a gallon sized ziploc bag. With bag open, roll dough into a log at the bottom of the bag, filling the entire width of the bag. Close bag removing as much air as possible.
 - Refrigerate for at least 2 hours or up to 2 days.
 - Preheat oven to 325º F. Line a baking sheet with parchment paper or a silpat.
 - Cut open the ziploc bag and place the dough on a cutting board. Cut the log in approximately 1/4 inch thick circles and place on prepared baking sheet.
 - Using a fork poke holes into the middle of each cookie.
 - Bake for 18-20 minutes.
 - Dust with confectioners' sugar as soon as the cookies come out of the oven.
 - Cool completely on a wire rack.
 - Store at room temperature in an airtight container for up to 3 weeks.
