The Southern dessert made from baked apples, sugar, and pastry or biscuit dough is called apple cobbler.
A cobbler consists of fruit baked beneath, or sometimes surrounded by, a topping that resembles rough biscuits, dumplings, or pastry. Apple cobbler uses seasoned apples, sugar, and often cinnamon, with the topping browning as the fruit softens.
Cobbler developed in North America as an adaptable fruit dessert. Its informal, uneven topping distinguishes it from a neatly crimped double-crust pie. Recipes vary considerably, so some use biscuit dough while others use cake-like batter.
Apple pie has a continuous pastry crust and is a different dessert. Peach cobbler uses peaches rather than apples, while Brown Betty traditionally uses buttered breadcrumbs or crumbs instead of a biscuit-style topping.
