The results are in for the Chocolate Decadence. I'd call it an unqualified success.
It was cut into about twenty pieces even though it was small, it was intense. The recipe called for 16 but some of the larger pieces were cut in half. I had canned whipped cream since there was no real way to whip it at work. Most of it disappeared pretty quickly. When there was still 1 piece left an hour later, I wrapped it up and took it home to cindygerb.
About the only problem was that it was very crumbly. I suspect that the chocolate that was used in other recipes probably had a bit more cocoa butter. So, next time, I'll add a bit more butter to it.
