Whether you dunk them in milk, pry them apart, or devour them whole, sandwich cookies are irresistible. These, with their crisp chocolate wafers and ganache filling made from fine-quality white chocolate, are so much better than that supermarket version.

Cook's notes:

· Dough can be chilled up to 2 days. · Ganache can be made 1 day ahead and chilled, its surface covered with parchment. Bring to room temperature, then beat with mixer before using. · Sandwiched cookies keep, chilled, 4 days.
