Cake
1 (18 1/4 ounce) box yellow cake mix
1/2 cup butter
1 egg
Filling
3 cups pumpkin pie mix
2 eggs
2/3 cup milk
1/2 teaspoon cinnamon

1/2 cup sugar
1 teaspoon cinnamon
1/2 teaspoon ground nutmeg
1/4 cup butter, softened

Preparation

Preheat oven to 350\u00b0F; grease or spray a 9x13 cake pan.
Stir together cake ingredients, reserve 1 cup for the topping, press the rest of the mixture into the bottom of your pan.
Mix together filling ingredients pour over the cake layer.
Combine topping ingredients sprinkle over the filling layer.
Bake 45-50 minutes, cool.

Notes:
I seldom use cake mix, when I do it's always Duncan Hines, use the classic yellow.
For extra crunch add 1/2-3/4 cup of chopped walnuts to the topping.
