I have a question about the recipe "Late Summer Plum Cake" from JSCooks.
What can I use instead of sour cream?

You can use plain yogurt, I have done this before and it works very well. I like the greek yogurt the best.
It has to be non dairy!
Maybe soy yogurt would work. I know that my whole food store has soy sour cream I don't know where you live or what you have access to but I am sure you could find soy yogurt.
