Dorayaki (どら焼き, どらやき, 銅鑼焼き, ドラ焼き) is a type of Japanese confection, а red-bean pancake which consists of two small pancake-like patties made from castella wrapped around a filling of sweet Azuki red bean paste. Dorayaki are similar to Imagawayaki, but the latter are cooked with the batter completely surrounding the bean paste filling and are often served hot. The original Dorayaki consisted of only one layer. Its current shape was invented in 1914 by Usagiya in the Ueno district of Tokyo.
