Gooey Butter Cake

In honor of Kate's birthday I made Gooey Butter Cake.  It's her favorite dessert at the Sailaway Cafe in Afton, MN (and mine too). It's not quite the same, but still great.  I thought it was going to be difficult to make given how delicious it is, but it's surprisingly simple, and the base of the crust uses a cake mix. 

Yield: 1 (9x13) cake pan (It's up to you to decide piece size)
Oven Temp: 350°F

Cake:
1 (18 1/4 oz) pkg yellow cake mix
1 egg
8 TBS unsalted butter, melted

Filling:
1 (8 oz) pkg cream cheese, softened
2 eggs
1 tsp vanilla
8 TBS unsalted butter, melted
1 (16 oz box) powdered sugar

Preheat oven to 350°F.  Combine cake mix, egg, and butter in a large mixing bowl.  Pat the mixture into the bottom of a lightly greased 9x13-inch baking pan.

In a large bowl, beat the cream cheese until smooth.  Add the eggs, vanilla, and butter and mix together.  slowly add the powdered sugar and mix well.  Spread over cake batter and bake for 40-50 minutes.  Make sure not to over bake as the center should be a little gooey. 

Store in the refrigerator and when ready to eat microwave a piece for 10-15 seconds.
