The oldest recipe for an oliekoek, an oil cake of dough, raisins, apples and almonds, is in a Dutch cookbook from 1667. By 1868 the word was oliebol, oil ball, and that is what the Netherlands eats on New Year's Eve: tens of millions in a single week, two or three per person, most of them plain or raisin.
Dutch settlers brought the olykoek to New Amsterdam. In 1809 Washington Irving described "balls of sweetened dough, fried in hog's fat, and called dough-nuts, or olykoeks." That sentence is the usual case for the oliebol as the ancestor of the American donut.
The towns that kept the original were built by 19th-century Dutch Reformed emigration: Holland and Grandville in Michigan, Pella in Iowa, Lynden in Washington. A warning about the word Dutch, though. Most donut shops with it in the name have no tie to the Netherlands at all, and Pennsylvania Dutch means German. The stops below are the ones that hold up.
