I have made this before using milk, but had never thought to use whipping cream instead because of the carbs in milk.
Anyway, I buy the Jello brand Sugar-Free chocolate pudding (I don't like instant, so I buy the kind you have to cook) and instead of milk, I add 2 cups of whipping cream and cook it that way. It is extra rich, so you actually only eat a couple of table spoons to get your chocolate fix. It is extra thick and yummy. There is only 6 grams of carbs per serving (which is 1/2 cup size). I can't find any hidden carbs so I think that is it. Anyway, it is very good if it is that time of the month and you are having a chocolate craving......
