Mini donut maker appliances are available from brands such as Babycakes, Nostalgia Electrics, SmartPlanet, Bella and Sunbeam. Home donut machines typically bake four to seven donuts at once and don't require any deep frying.
The most common donut machines consist of upper and lower baking plates with nonstick coating, similar to a waffle iron. After filling the donut molds on the lower plate, close the lid and allow the donuts to bake and rise into a uniform shape. The Nostalgia Electrics model is an automatic donut factory, which completely forms the donuts inside the machine and moves them along a conveyor belt to an exit chute.
