1 box spice cake mix
1/2 cup melted butter (1 stick, melted)
1 can pureed pumpkin
1 pack of cream cheese, softened
2 cups unpacked powdered sugar
1 tsp vanilla
2 tbsp cinnamon
2 tbsp melted butter
Mix together the 1/2 cup butter, spice cake mix, and 1 egg. Grease a 9 x 13 pan and spread this mixture in the bottom.
In another bowl, beat pumpkin, cream cheese, vanilla, 1/2 of the cinnamon, and butter together. Beat eggs in a small bowl and mix them in. Mix powdered sugar in just enough to incorporate well.
Pour this mixture on top of the spice cake mixture. Sprinkle rest of cinnamon on top.
Bake at 350 degrees for about an hour (give or take 5 minutes depending on your oven). Let cool for about 30 minutes (if you can wait :)). Serve warm with whipped cream.
