Give yourself a reason to invite a couple friends over for coffee or tea with these delicious Coffee and Hazelnut Shortbread cookies. Made with toasted hazelnuts, these coffee and vanilla flavored shortbread cookies have a lovely crunch in each bite. Refrigerate the dough before shaping and baking. Add a melted chocolate garnish for the finishing touch. You can pipe stripes of chocolate or melt chocolate and dunk the shortbread into the chocolate, it is up to you!
