Directions:

Preheat oven to 350 degrees. Combine pumpkin, evaporated milk, eggs, sugar, cinnamon, and salt in a large bowl. (I used my mixer for this step.) Pour into a greased 13×9 baking dish.
Run cake mix through a sifter to get lumps out and sprinkle dry cake mix evenly over pumpkin mixture. Top with pecans. Drizzle melted butter over pecans. Bake for 50-55 minutes or until golden brown. Cool. Serve chilled (or warm). Top with a dollop of whipped topping.
