These special spots are putting sweet spins on American classics. The Doughnut Project in New York City offers savory-meets-sweet doughnuts, including a doughnut crossed with an everything bagel, and a chocolate cream doughnut flavored with bone marrow. In Miami, Sweetness Bake Shop gives childhood favorites tropical Latin twists, like a cinnamon-spice doughnut filled with dulce de leche and topped in chocolate frosting and a crispy churro. At The Dirty Cookie in Tustin, Calif., milk and cookies combine in edible cookie shot glasses!
