Since I am limited on cake chemistry and behavior I have only one thing to offer...have you checked the freshness of your baking powder and soda?
Also, weather often affects cakes...has it been particularly humid? I have trouble with chocolate cake rising enough when it's raining outside.
Thank for your reply. Yes we bought new cake flour new baking powder and new baking soda . Im going to clear my head and try it again hopefully third time is a charm .
If I am reading your post correctly, you used Italian custard instead of sour cream?
If the chemical content of the two ingredients is not the same or similar with respect to fat content, moisture content, acidity, etc, then it seems that the substitution would be the thing most likely to be causing your problem. Baking is pretty complicated chemistry. Just because something looks like something else, it doesn't follow that you can substitute.
