Pumpkin Gooey Bars

CAKE:
1 package of yellow cake mix (I use betty crocker)
1 egg
8 - 10 Tbs of butter (the more butter the softer), melted

FILLING:
1 (8-oz) package of cream cheese, softened
1 (15-oz) can of pumpkin
3 eggs
1 tsp of vanilla (a tiny drip more won't hurt)
8 Tbs of butter, melted
1 (16-oz) box powdered sugar
1 tsp cinnamon
1 tsp nutmeg

DIRECTIONS:
Preheat oven 350 degrees

Combine cake mix, egg & butter. Mix well with electric mixer. Pat mixture into bottom of lightly greased 13 x 9 inch baking pan. For the filling beat cream cheese and pumpkin until smooth in a large bowl. Add eggs, vanilla and butter, then beat together. Next add powdered sugar, cinnamon, nutmeg and mix well. Spread pumpkin mixture over cake batter and then bake for 40 to 50 minutes. Be careful to not overbake. The bars will continue to set even out of the oven. The middle of the bars will be slightly jiggly when taken out of the oven.

The bars are great on their own or with whipped cream.
