Better than pumpkin pie! In the style of an upside down cake, you flip after baking then top with a sweetened cream cheese spread.
Preheat oven 350 degrees. Line 13x9x2 pan with wax paper.
Combine first five ingredients until smooth; pour into pan. Sprinkle dry cake mix on top of mixture and pat lightly. Sprinkle nuts on top of cake mix and pat lightly. Pour margarine over all.
Bake 50 to 60 minutes until firm. Let cool and then turn over onto serving platter. Remove wax paper.
In a large bowl, blend topping ingredients until smooth then spread over crisp.
