Pumpkin Gooey Butter Cakes (and other variations)

(From Paula Deen on the Food Network)

This cake is absolutely my new favorite pumpkin dessert! Sooooo good! It is very rich and sweet, but that doesn't stop me from having seconds. Yummy, yummy, yummy!!!

Cake:
1 (18 1/4-ounce) package yellow cake mix
1 egg
8 tablespoons butter, melted
Filling:
1 (8-ounce) package cream cheese, softened
1 (15-ounce) can pumpkin
3 eggs
1 teaspoon vanilla
8 tablespoons butter, melted
1 (16-ounce) box powdered sugar
1 teaspoon cinnamon
1 teaspoon nutmeg

Preheat oven to 350 degrees F.

Combine the cake mix, egg, and butter and mix well with an electric mixer. Pat the mixture into the bottom of a lightly greased 13 by 9-inch baking pan.

To make the filling: In a large bowl, beat the cream cheese and pumpkin until smooth. Add the eggs, vanilla, and butter, and beat together. Next, add the powdered sugar, cinnamon, nutmeg, and mix well. Spread pumpkin mixture over cake batter and bake for 40 to 50 minutes. Make sure not to overbake as the center should be a little gooey.

Serve with whipped cream.

Variations: For a Pineapple Gooey Cake: Instead of the pumpkin, add a drained 20-ounce can of crushed pineapple to the cream cheese filling. Proceed as directed above.

For a Banana Gooey Cake: Prepare cream cheese filling as directed, beating in 2 ripe bananas instead of the pumpkin. Proceed as directed above. (You could also use a chocolate cake mix for this variation, yum!).

For a Peanut Butter Gooey Cake: Use a chocolate cake mix. Add 1 cup creamy peanut butter to the cream cheese filling instead of the pumpkin. Proceed as directed above.
