- At least 2 hours to solidify the assembled ice cream sandwiches", "For the crispiest cookies and brightest flavors, assemble the ice cream sandwiches the same day you plan to eat them. You can assemble these up to one week ahead of time, but the cookies will soften and the flavors will mellow the longer that the sandwiches are stored.", "To prepare the ice cream, put it in the refrigerator for 20 minutes to let it soften slightly. (Set a timer!)", "Get the cookies ready, arranging half of them upside down on a baking sheet.", "At Bi-Rite Creamery we use silicone molds to create perfectly round ""pucks"" of ice cream for ice cream sandwiches, though you can get a similarly uniform shape by using a dry measuring cup as a mold for the ice cream. Or, you can get a more handmade look by simply scooping a large scoop of ice cream onto a cookie, sandwiching it with a second cookie, and pressing on the cookies slightly.", "Freeze the sandwiches, putting the baking sheet in the freezer to let them harden for at least two hours. If you're storing the sandwiches for longer than one day, transfer the hardened sandwiches to zip-top freezer bags, being sure to squeeze out any excess air before sealing."]
