Pumpkin Delight

This is a recipe that I got from my sister-in-law, Karen Reid, years ago. She loved to make it instead of pumpkin pie.

1 yellow cake mix (set aside 1 cup)
1/4 cup melted butter
1 beaten egg
Mix together these three ingredients and press into 9x13 cake pan.

Filling:
1 large can pumpkin
2 eggs
2/3 cup milk
2 1/2 teaspoon pumpkin pie spice
1/2 cup brown sugar
1/2 cup sugar
Mix the filling ingredients together and then pour over the cake mixture in 9x13 pan.

Topping:
1 cup cake mix
1/4 cup softened butter
1/4 cup sugar
1 teaspoon cinnamon
Mix the topping ingredients together until crumbly and then put on top of filling.

Bake at 350 degrees for 50-60 minutes.
