1 pkg. Pillsbury yellow cake mix
1 egg
1/2 c. butter, melted

FILLING:

3 c. pumpkin pie filling (Libby's mix)
2 eggs
2/3 c. milk

TOPPING:

1 c. reserved cake mix
1/4 c. sugar
1 tsp. cinnamon
1/4 c. butter, don't melt

Grease bottom only of a 9x13 pan. Reserve 1 cup cake mix for topping. Combine cake mix, butter and egg. Press in pan. Mix ingredients for filling until smooth. Pour over crust.

Combine ingredients for topping. Sprinkle over filling. Bake at 350 degrees for 45-50 minutes (until toothpick comes out clean).

If you use pumpkin (regular instead of mix), use about 2 1/2 cups pumpkin, 2 1/2 teaspoons pumpkin pie spice, 1/2 cup firmly packed brown sugar.
