Preheat oven to 300 and grease a 9x13 baking with nonstick cooking spray.

Mix cake mix, melted butter and one egg to form a soft dough.

Press into the bottom of the baking dish.

Mix powdered sugar, cream cheese and remaining 2 eggs until smooth, about 1-2 minutes.

Pour on top of the crust.

Bake at 300 for 45-50 minutes until the top is golden brown.

Let the cake cool 15 minutes before serving.
