Preheat oven to 400F.
Cut tortillas into triangles and place in a large mixing bowl.
Line baking sheets with parchment paper, silpats or spray with a non-stick spray such as Pam.
Pour melted butter over the tortillas and add 3/4 of the sugar, the pumpkin spice mix, and two tsp of the cinnamon. Toss well to coat.
Arrange the tortillas on the baking sheets in one layer. Bake for 5 minutes on one side, remove from the oven, flip chips to other side and bake for another 5 minutes.
While chips are baking, mix the remaining sugar and cinnamon to create cinnamon sugar.
Remove the chips from the oven and sprinkle with the cinnamon sugar. Add to a plate, and top with caramel sauce (if desired) and whipped cream (if desired).
Note: This makes one plate of dessert nachos
