In large mixing bowl add pumpkin, milk, eggs, sugar,vanilla and salt. Mix well for 2 minutes medium speed.Pour in cake pan.
In another bowl with melted butter add cake mix and nuts. I start out adding 1/3 cake mix and 1/3 nuts and stir. I repeat this till its all mixed and crumbly. Evenly top pumpkin mixture. Don't be alarmed since topping is heavy it tends to sink into pumpkin.
Bake at 350 degrees for 1 hour. Warm or cold if you like pumpkin you will certainly enjoy this!
