These were pretty good. I made them for my family, me and my mom ate them, however my dad ate one and was done. They were very rich, so I would use white chocolate instead of bittersweet, to lessen the richness. I would recommend not softening the butter, makes it harder to make the crumb mixture. Also, you need to refrigerate them when they come out of the oven, otherwise you'll wait for hours for them to cool enough to cut. Other than that it was good.
