Step 1

Preheat the oven to 350°F and spray a 9x13-inch light colored metal baking pan with nonstick cooking spray. Set aside.

Step 2

Use a mixer to combine the cake mix, softened butter, and egg together. Mix until just combined. Pat the mixture evenly into the prepared pan.

Step 3

Reserve about 1/3 cup of the powdered sugar and set aside for the topping.

Step 4

Use a mixer to beat the cream cheese until smooth. Add the powdered sugar and eggs and beat until combined. Pour the mixture over the crust.

Step 5

Bake for 30 to 35 minutes or until the edges are just lightly brown, but the center is still jiggly. Cool completely then cut into squares and dust with reserved powdered sugar.
