I'm not sure if there are some ingredients missing, or there's a typo somewhere in there, because I followed the cake recipe and it was so not good. In fact I threw it all away. It was sour, not done (even with extra baking time)and really didn't smell good. I understand that it was going to be different being "fat free" but this was far too different for me. I would suggest less sour cream, more cream cheese, less lemon juice and some form of egg to help it set up.
