Heat the oven to 375°F, cut any large apple slices into smaller pieces and spread the filling in a 9-by-13-inch dish.

Cut each biscuit into quarters and arrange the pieces loosely over the apples.

Brush the biscuit pieces with melted butter and sprinkle evenly with cinnamon sugar.

Bake for 30 to 35 minutes until the dough is browned and cooked through at the center.

Rest 25 minutes before serving.
