A doughnut or donut ( /ˈdoʊnət/ or /ˈdoʊnʌt/) (see spelling differences) is a type of fried dough confectionery or Dessert food. Doughnuts are popular in many countries and prepared in various forms as a sweet snack that can be homemade or purchased in bakeries, supermarkets, food stalls, and franchised specialty outlets. They are usually deep-fried from a flour dough, and shaped in rings or flattened spheres that sometimes contain fillings. Other types of batters can also be used, and various toppings and flavorings are used for different types.
The two most common types are the toroidal ring doughnut and the filled doughnut, a flattened sphere injected with fruit preserves, cream, custard, or other sweet fillings. A small spherical piece of dough may be cooked as a doughnut hole. Doughnut varieties are also divided into cake and risen type doughnuts. Other shapes include rings, balls, and flattened spheres, as well as ear shapes, twists and other forms.
