Gooey butter cake is a type of cake traditionally made in the American Midwest city of St. Louis. Gooey butter cake is a flat and dense cake made with wheat cake flour, butter, sugar, and eggs, typically near an inch tall, and dusted with powdered sugar. While sweet and rich, it is somewhat firm, and is able to be cut into pieces similarly to a brownie. Gooey butter cake is generally served as a type of coffee cake and not as a formal dessert cake. There are two distinct variants of the gooey butter: a bakers’ gooey butter and a cream cheese and commercial yellow cake mix variant. It is believed to have originated in the 1930s.
