A Dutch baby pancake, sometimes called a German pancake, a Bismarck, a Dutch puff, or a Hootenanny, is a large American popover.
A Dutch baby is similar to a large Yorkshire Pudding. Unlike most pancakes, Dutch babies are baked in the oven, rather than being fried. They are generally thicker than most pancakes and contain no chemical leavening ingredients such as baking powder.
They can be sweet or savory and can be served at any meal.
The idea of a Dutch baby pancake may have been derived from the German Pfannkuchen, but the current form originated in the US in the early 1900s.
