Set the oven to preheat at 400°F. Empty the contents of both apple pie filling cans into an 8x8-inch baking dish, spreading evenly.
Dust the surface of the filling with ground cinnamon to enhance the flavor.
In a separate mixing bowl, add the flour and sugar along with the cubed cold butter.
Utilize a fork or pastry cutter to integrate the butter into the dry mixture until it forms a crumbly texture resembling coarse pebbles.
Incorporate the chopped pecans into the crumble topping, mixing to distribute evenly.
Evenly scatter the topping mixture over the prepared apple filling in the dish.
Position the dish on the center rack of the oven and bake for 25 to 30 minutes, or until the top has turned a light golden hue and the filling is visibly bubbling around the edges.
