Here`s one with Bisquick that makes its own crust.
3/4 C Sugar
1/2 C Bisquick
2 TBSP Butter
1 13 oz can evaporated milk
2 eggs
1 16 oz can pumpkin
2 1/2 tsp pumpkin pie spice
2 tsp vanilla
Heat oven to 350°
Grease pie pan
Beat all ingredients till smooth
Pour in pie pan
Bake 50-55 minutes
My recipe doesn`t state what kind of pumkin but I assume it`s puree since they`re adding pumpkin pie spice. I would think you could substitute pie filling and skip the spice?
