Preheat oven to 350 degrees and lightly grease a 9X13-inch baking pan.
In a large bowl, stir together cake mix, egg, and melted butter until mixed well. Press mixture into bottom of prepared pan and set aside.
Using an electric mixer, beat cream cheese until smooth. Add pumpkin and beat until blended.
Beat in eggs one at a time.
Add vanilla, melted butter, confectioners' sugar, cinnamon, nutmeg, and cloves and beat to combine.
Pour batter into prepared pan over bottom layer.
Place in oven and bake for 50 minutes. Let cool before slicing. I like to refrigerate it.
Notes
Be sure to use Pumpkin puree and NOT pumpkin pie filling.Confectioners' sugar tends to clump together. It will mix into the batter better if you sift it first to remove any lumps.Leftovers should be refrigerated.
