Unlike most donut shops, Duck Donuts turns the sweet treat into an exercise in personal expression. Each one of its vanilla cake donuts is made to order. Customers first choose from a variety of coating, like lemon, vanilla, or peanut-butter icing. Then, they can top off their creations with sprinkles, nuts, or real bacon pieces. Finally, a hot-fudge, berry, or caramel drizzle can complete the tasty construction project. Duck Donuts is now located in two spots in the Maryland area.
