Glazed

A "glazed donut" commonly refers to a plain, yeasted donut in a sweet sugar glaze, though many other types of donut have glazes, as well.

(Like a "cheese slice" refers to pizza with just tomato sauce and cheese, though many pizzas have both tomato sauce and cheese in addition to other ingredients.) Just about every American doughnut shop will make some version of these.

Chocolate glazed is a common variant, a plain yeasted donut with a chocolate-flavored glaze, though in this case, the chocolate tends to glaze only the top, rather than over the entirety of the surface; sides and bottom are left unglazed, or treated with a plain sugar glaze.
