Does anyone have the recipe for the dessert William Hamilton wrote about in his column on entertaining in the Times a few weeks ago? (Sunday Styles section, I think) In the story he talks about how he had a party based on a party in an entertaining book that recently came out. His friend came in at the end of the party with some sort of dessert that everyone loved. Some sort of layered dessert bar or brownie, I think.
Thanks in advance!
