Preheat oven to 375°F (190°C). Spray an 8×8-inch baking dish with nonstick spray.

In a bowl, mix the peeled and diced apples with the sugar, cornstarch, cinnamon, and nutmeg until evenly coated.

Unroll the cinnamon roll dough and cut the rolls into ½-inch strips. On a floured surface, roll out each strip until fluffy and thin. Use flour as needed to prevent sticking.

Arrange the first layer of flattened cinnamon roll dough on the bottom and sides of the prepared baking dish.

Spread half of the apple mixture over the dough and drizzle 2–3 tablespoons of caramel sauce on top.

Cover with another layer of cinnamon roll dough strips and spread the remaining apple mixture and pour more caramel sauce on top.

Cover with the remaining flattened cinnamon roll dough.

Cover the dish with aluminum foil and bake for 30 minutes.

Remove the aluminum foil and bake for another 10–15 minutes, or until the top is golden brown.

Let the dish cool for at least 30 minutes.

Drizzle the icing that comes with the cinnamon rolls over the top before slicing and serving.
