I want to make a parfait with jello on the bottom, yogurt in the middle and then a layer of chocolate pudding on the top. I would really like to be able to put a hard chocolate crust on top of it, then a dab of whipped cream w/ strawberries and blueberries on top...and maybe a chocolate kiss in the middle. Any thoughts on how to make the chocolate "crust"? I tried googling on icing but all I found were frosting recipes - the soft kind.
