A
sweet roll or
sweet bun refers to any of a number of sweet, baked,
yeast-
leavened breakfast or
dessert foods. They may contain
spices,
nuts,
candied fruits, etc., and are often
glazed or topped with
icing. Compared to regular bread
dough, sweet roll dough generally has higher levels of sugar, fat, eggs, and yeast. They are often round, and are small enough to comprise a
single-serving. These differ from
pastries, which are made from a
paste-like
batter; from
cakes, which are typically unleavened or chemically leavened; and from
doughnuts, which are
deep fried.
