For many of us, the local bakery becomes a second holiday home where we can stop in for a quick pound or two of green-and-pink sandwich cookies shaped like leaves and layered with chocolate, tricolor sponge cookies, and—best of all—cookie sandwiches slathered with jam and dusted with powdered sugar. Wouldn't these be even better, though, if they were homemade? Believe it or not, jam-filled cookies are easy to make ahead of time; our raspberry sandwich cookies require only five ingredients, and their buttery dough can be prepped in advance and chilled overnight. So, if you find that you have time on your hands to turn on your own oven, you can enjoy a bakery classic without having to go to the bakery. —The Editors
