Even if Grandma's cookies are the best, she still appreciates someone else baking for her on occasion. We love these massive cookies from New York's Levain Bakery. One cookie goes a long way, and if you pop them in the oven for a few minutes, they come out with a marvelous ooey, gooey center. Get a 4-pack for $29, an 8-pack for $49, or a 12-pack for $79.
