Special equipment: 10 (5-inch) removable bottom tart pans
Preheat oven to 350 degrees F.
Cake: Combine the cake mix, egg and butter and mix well with an electric mixer. Divide the mixture into 10-equally sized balls. Flatten each ball with the palm of your hand and gently press into the bottom of each tart pan.
Filling: In a large bowl, beat the cream cheese and pumpkin until smooth with an electric mixer. Beat in eggs, vanilla and butter. Add the powdered sugar, cinnamon, nutmeg, and mix well. Spoon a scant 1/2-cup of the pumpkin mixture over cake batter in the tart pans and bake for about 40 minutes. Make sure not to over bake as the center should be a little gooey. Let cool in the pans for 10 minutes before removing.
Serve with fresh whipped cream and candy topping.
