1 regular size box chocolate cake mix
1/2 cup butter, melted
3/4 cup chopped pecans, optional
1 (8 ounce) package cream cheese
1 pound powdered sugar
Preheat oven to 350 degrees F. Prepare a 9 x 13-inch baking pan with cooking spray.
In a large bowl, combine dry cake mix, butter, and egg. Stir in pecans, if desired. Batter will be very stiff. Spread evenly in the prepared pan.
In a separate bowl, beat together cream cheese, eggs, and powdered sugar until smooth. Spread over first layer. Bake for about 30 minutes. Allow to cool, cut into squares.
