Doughnuts are a type of fried dough confection, typically sweet and often ring-shaped or filled. The classic dough is made from flour, sugar, eggs, butter, and a leavening agent, then deep-fried and finished with glaze, frosting, or toppings. While enjoyed worldwide, their modern form is strongly associated with American cuisine and diner culture.
Doughnuts are very high in carbohydrates and fat, with minimal protein. They primarily provide quick energy from sugars and refined starches, along with some fat-soluble vitamins from the frying oil and dairy ingredients.
