So delicious! Quick, easy, and inexpensive. Highly recommend the suggestion of the cooking 15 minutes instead of the whole 20 minutes. I put a full cup of peanut butter plus maybe a little more ;) we love peanut butter and some comments mentioned it wasn't quite peanut buttery enough. It was perfect for us. I made some chocolate pudding and made a parfait type thing with pudding on the bottom, then a slice of speedy little devil, with a scoop of ice cream on top. whoooooeeeee, very rich. very yummy.
