Preheat oven to 375°F (190°C). Spray a 12-cup standard muffin tin with nonstick baking spray.

Lightly flour a work surface. Open the cinnamon roll package and remove one cinnamon roll. Flatten it with your fingertips on the work surface (you can also use a rolling pin).

Then press the flattened cinnamon roll into one muffin cup to fit. Repeat for the remaining muffin cups.

Spoon apple pie filling into each muffin cup until 3/4 full.

Bake for 15-18 minutes or until puffy and golden.

Remove from the oven and cool in the pan for 10 minutes.

Slide a small spatula around the edges to remove the cups.

Optional: Heat the icing in the microwave for 10 seconds on low-power and then drizzle onto the cups. Alternatively, serve with ice cream or caramel sauce.
