I substituted another pudding for the one suggested, and it didn't set right. We had to keep it frozen in order to keep it solid, but that turned out to be just as good! Other than that, it was excellent! Next time I make it, I'll try to find the right pudding :) A good vegan whip cream: skim the creamy stuff off the top of a can of coconut milk, and whip with vanilla and powdered sugar.
I was looking for a low fat recipe. I had to substitute (guess) for brand name items. Hubbie likes it sweet, so I added 2T fructose. I topped it with meringue. Excellent taste and looks. Firmed up well.
