These bars are absolutely delicious!  I found 3 different recipes with 3 different names but the same ingredients!  Except one had pecans in the crust!  If you want a very sweet dessert - try these!

Nieman Marcus - Chess Squares - Bayou Brownies

1 box yellow cake mix
3 eggs
8 oz cream cheese, softened
1/2 cup (1 stick) butter, melted
4 cups (1 lb) powdered sugar

1 cup chopped pecans (this was in the recipe named Bayou Brownies)

 

Preheat oven to 300 and spray a 9×13 dish with cooking spray. Mix cake mix, melted butter and one egg to a soft dough (add pecans here if you want pecans). Press into the bottom of the pan. Mix powdered sugar, softened cream cheese and remaining two eggs until smooth, about 1-2 mins. Pour on top of crust. Bake at 300 for 40-50 minutes until top is golden brown.
