Preheat oven to 350˚ and spray a 9x13 cooking pan with cooking spray. Mix together the cake mix, one egg and 6 Tablespoons melted butter with a hand mixer. Using a spatula, pat this mixture into the bottom of the baking dish. Spread the strawberry slices in an even layer over this cake mixture. Mix together the cream cheese, another 6 Tablespoons of melted butter, 2 eggs, vanilla and powdered sugar until smooth. Carefully spread this cream cheese mixture over the strawberries and cake. Bake for 40-45 minutes, until golden brown on top and cake is set. Cool before serving.
