It consists of a rolled sheet of yeast-leavened dough onto which a cinnamonand sugar mixture (and raisins or other ingredients in some cases) is sprinkled over a thin coat of butter. The dough is then rolled, cut into individual portions, and baked or deep fried. In North America, cinnamon rolls are frequently topped with icing (usually confectioners' sugar based) or a glaze. In Northern Europe, nib sugar is usually used with a glaze instead of icing. Commonly in North America, these rolls are fried, glazed, and served as a variation of a raised donut.
The size of a cinnamon roll varies from place to place, but many vendors supply a smaller size about 5 centimetres (2.0 in) in diameter and a larger size about 10 centimetres (3.9 in) to a side. The largest variety can be found in Finland, called Korvapuusti, where it can be up to 20 centimetres (7.9 in) in diameter and weighing 200 grams (7.1 oz)
The Finnish "Boston cake" is a "cake" made by baking cinnamon rolls in a round cake pan instead of baking them separately, so that they stick together to form a round cake.
