A cobbler uses a biscuit-like batter on top of the fruit. When a cobbler is baked, the topping can resemble a cobblestone street, which is actually where the dish gets its name. A crumble is a topping over the spiced fruit that typically includes a combination of butter, flour, sugar and sometimes nuts. A crisp is very similar to a crumble. The only difference is that a crisp includes oats and nuts in the topping to give it a crunchier texture.
