I just watched an episode of America's Test Kitchen. They did a blind tasting of different boxed cake mixes and liked Betty Crocker the best, (with real butter). The show was about lemon cake with lemon curd filling made from scratch.
I personally like the box mixes, the ones with ';pudding in the mix';
