Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
In a large bowl, mix together the cake mix, eggs, and melted butter until well combined.
Spread the cake mixture evenly in the prepared pan.
In another bowl, beat the cream cheese until smooth.
Add eggs and powdered sugar to the cream cheese and mix until creamy.
Pour the cream cheese mixture over the cake layer.
Bake for 40-45 minutes until the edges are set but the center is still gooey.
Cool the cake in the pan for about 30 minutes.
Cut into squares and serve warm or at room temperature.
