Yes. I was trying to do a dairy free SMBC. I made two batches. One with Earth Balance & high ratio shortening and the other with earth balance & palm shortening. The palm shortening tasted better but was way too soft and never did firm up (a problem for the high heat & humidity and stacking).
I went with the high ratio shortening and also added 2 teaspoons of cornstarch to help firm it up. If I have to do it again I will try 2 tsp of powdered sugar. Like I said, the raspberry flavoring helped a lot.
I know many people do dairy free but I am just not use to this taste and thought it was acceptable but It will not taste anything like regular SMBC. The person I made it for love it, so..........I guess that's what matters.
