Start by combining your cake mix, butter and 1 egg in a medium mixing bowl. It is supposed to be a bit crumbly, so do not worry if the dough seems a little bit dry.
Press into a greased 9x13" inch baking pan.
Beat cream cheese until smooth.
Add an egg, and powdered sugar. Mix until smooth.
Fold in your chopped pecans.
Pour on top and smooth out evenly.
Bake at 350° F and bake for about 30 minutes, until edges are light brown and the top is firm.
