A crispy, crunchy maple bar of sorts, these twice-baked, buttery cookies offer sturdy structure for dunking and dipping, not to mention portability. Tender chopped walnuts add a nutty crunch, while natural maple flavor and brown sugar bring sweetness and warmth. A drizzle of white icing further amps up the sweetness — these are cookies, after all — so this Biscotti looks nearly as good as it tastes, whether you enjoy it with a spot of tea, a robust espresso, a cozy cup of cocoa, or a mug of good, old-fashioned Pumpkin Spice Coffee.
