Preheat the oven to 350°F. Lightly grease a 9×13-inch baking pan.
In a large bowl, combine pumpkin, evaporated milk, eggs, sugar, pumpkin pie spice, and salt. Mix well and spread evenly in the pan.
Sprinkle the dry cake mix evenly over the pumpkin mixture. Gently pat it down but don’t stir. Scatter chopped pecans on top, then drizzle evenly with melted butter.
Bake for 60–80 minutes, or until the topping is golden brown and the center is set. Let cool before topping with whipped cream.

Notes
I’m not a dietitian, just a dessert enthusiast. Nutrition info is an estimate, calculated with frozen whipped topping—because what’s Pumpkin Crunch Cake without a little fluff on top?
