Cereals are the American breakfast staple that we all grew up with and often times, continue to grow with. The best part of cereals is the insane amount of varieties available. Using these popular choices as toppings on donuts has become one of the biggest hits in the gourmet donut area. Popular choices include lucky charms, cinnamon toast crunch, fruity pebbles, frosted flakes and many other cereal to play with.
