Preheat oven to 350 degrees. Using an electric mixer on low speed, combine cake mix, 1 egg, butter, and 2 teaspoons pumpkin pie spice until crumbly. Press into the bottom of a 9x13-inch dish; set aside.

In a large mixing bowl, beat cream cheese until fluffy. Gradually beat in sweetened condensed milk, remaining 2 eggs, pumpkin, remaining 2 teaspoons pumpkin pie spice, and salt. Mix well. Pour over crust; sprinkle nuts on top.

Bake 30 - 35 minutes or until a knife inserted in the center comes out clean. Cool to room temperature, then chill in the refrigerator. Makes 12 servings.
