Divide the dough in half. Smooth and shape each half of the
dough into an evenly shaped rectangle that is about 8 1/2 inches (21.5 cm) long and 2.5
inches (7 cm) wide. Then wrap the shaped logs in plastic wrap or parchment or
paper, and place in the
refrigerator to chill for at least three hours, or up to three days. (The logs can
also be frozen for about two months. If freezing, it is best to defrost the logs
in the refrigerator overnight before slicing and baking.)
Preheat oven to 325 degrees F (165 degrees C) with the rack in

Ganache: Meanwhile, place the chopped chocolate in a small bowl. Place the
cream in a small saucepan over medium heat and bring just to a boil (you can

the peppermint extract. Set aside to let the ganache completely cool and become
thick enough to spread, about two hours.
Assemble Cookies: Take one chocolate shortbread and spread a small
tablespoon of the ganache on the flat side of the cookie. Top with a second
shortbread, flat side down, and press gently so the ganache spreads to the edges
of the sandwich cookie. Repeat with the remaining shortbread cookies.
