Heat oven to 400°F.
Lightly spray 8 regular-size muffin cups with cooking spray.
Open your cinnamon roll dough and spread them out on your counter.
Flatten your dough so it is thin and it will be able to fill the majority of one of the muffin tin holes.
Next, fill your dough with pie filling.
Add a pinch of cinnamon on top of the apple filling.
Add a Tablespoon of brown sugar on top of the cinnamon.
Last, add a few walnuts on top of the brown sugar of each one.
Cook in the oven at 400 degrees for 8 to 12 minutes, or until golden brown.
When they are done cooking take them out and let them cool for a few minutes.
Top with Cool Whip, more walnuts, and caramel sauce.
Serve while warm.
