A bits-and-pieces dessert: you need vanilla ice cream, hot fudge sauce, and a lot of broken bits of brownie.
No, I didn't have a kitchen disaster, although that could get you there as well. But recently I made a large pan of regular-old-brownies for company, and I had a lot of little bits and ends that didn't cut well. I broke them all up--not into crumbs, but into small pieces--froze them in a plastic container, and then thawed them just before making dessert. I made the fudge sauce while I was making dinner too.
And you can figure out the rest: a small helping of brownie bits in the bottom of the bowl, a scoop of ice cream on top, and sauce on top of that. We felt completely decadent.
