Cobblers include a fresh (or frozen) fruit filling baked in a baking dish and topped with a sweet biscuit-like topping (which, you may have noticed, has a very “cobbled” appearance). Crisps also have fruit on the bottom, but they have thinner, crispier, and crumblier tops made primarily of butter, sugar, and oats. If you're looking for a crisp recipe, please check out my apple crisp, berry crisp or peach crisp! Bon Appetit has a breakdown on the differences if you want to read more on the subject!
