I currently have one problem with Marybeth's: I can't eat chocolate because it bothers Smash. As in he screams and refuses to eat or to sleep in his bed for approximately 12 hours--so it's definitely not worth it to eat anything chocolate, no matter how good it is.
Ryan, being the great husbnad he is, decided he was going to make me a lemon Marybeth's cake. And guess what? It was delicious.
