A fruit crisp has a fruit filling topped with a streusel. In a crisp, the crunchy streusel topping has oats in it. Typically rolled oats are used. Fruit crumble is also fruit filling topped with streusel but without oats. Cobblers are similar to crisps and crumbles in that they have a fruit filling with no bottom crust. However, instead of a streusel topping they have a fluffy, baked biscuit on top of the fruit filling.
