The ingredients and preparation are so similar that they seem almost interchangeable, but here is how they differ: • Crisp: The topping of a crisp contains butter, sugar, and oats sprinkled over fresh fruit. • Crumble: Fresh fruit is topped with a crumble made with butter, sugar, and flour. • Cobbler: Dollop fresh fruit with a flour or dough mixture to create the illusion of cobbled roads.
