A dessert called "buckle" typically refers to a type of fruit dessert in American cuisine. It is made with fresh fruit, often berries or stone fruits, mixed into a cake-like batter and topped with a streusel-like crumb topping. As the dessert bakes, the batter rises and surrounds the fruit, creating a slightly "buckled" appearance. The name "buckle" comes from the way the cake buckles or wrinkles during baking. Blueberry buckle is a popular variation of this dessert.
