Preheat oven to 350 degrees Fahrenheit. Lightly grease the bottom of a pie pan and set aside.
On a lightly floured surface, roll out 12 cinnamon rolls with a rolling pin until flattened and doubled in size (1 1/2 cans). Evenly place the cinnamon rolls throughout the bottom and sides of the pie pan to form a crust. Pinch together any holes. Bake for 7 minutes and remove from oven and set aside.
Peel, core, and slice apples into 1/2-inch slices and place in a medium-sized bowl. Add cranberries, sugar, cornstarch, and cinnamon and stir together until the fruit is covered. Pour the filling into the bottom pie crust.
Roll out the remaining 12 cinnamon rolls and evenly place over the top of the pie to form the top crust. Cover with aluminum foil and bake for approximately 40-50 minutes. Check the underside of the top crust to ensure it is cooked through and not raw. If it is not cooked, cover and continue to bake, checking often until completely cooked through. Then remove the foil and bake an additional 8-10 minutes until the top is golden brown.
Remove pie from oven and allow to fully cool at least 3 hours. Drizzle with cinnamon roll icing and enjoy!
