Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.
Peel, core, and dice apples, then mix them with sugar, cinnamon, nutmeg, and cornstarch in a saucepan over medium heat until soft and caramelized.
Unroll the cinnamon rolls, slightly flatten them, and arrange them in layers in the baking dish.
Spread the apple filling over the first layer, then repeat with another layer of cinnamon rolls.
Drizzle caramel sauce over the top for extra indulgence.
Bake for 25-30 minutes or until golden brown and bubbling.
Let it cool for a few minutes, then drizzle more caramel sauce if desired.
Serve warm and enjoy with ice cream or whipped cream!
