Preheat the Oven:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with non-stick spray or butter.

Prepare the Tortillas:
Lay out the flour tortillas on a clean surface. Spoon an equal amount of apple pie filling (about 1/3 cup) onto the center of each tortilla. Sprinkle a pinch of cinnamon over the filling.

Roll the Enchiladas:
Fold the sides of the tortilla over the filling, then roll it up tightly from the bottom to create a cylinder. Place the rolled tortillas seam-side down in the prepared baking dish.

Make the Sauce:
In a medium saucepan, melt the butter over medium heat. Add the white sugar, brown sugar, and water. Stir continuously until the sugars dissolve and the mixture comes to a gentle boil. Remove from heat.

Assemble and Bake:
Pour the warm sugar sauce evenly over the rolled tortillas in the baking dish. Make sure each enchilada is well-coated. Bake in the preheated oven for 20-25 minutes, or until the tortillas are golden brown and the sauce is bubbly.

Cool and Serve:
Remove the dish from the oven and let it cool for 5-10 minutes. Serve warm, optionally topped with a scoop of vanilla ice cream or a drizzle of caramel sauce.
