Coffee, chocolate, and mascarpone cream...... how much better does it get? These are a Daniel Boulud recipe, baked (of course!) in paper espresso cups. They have a mocha ganache and mascarpone cream whipped on top. You can see all the photos and recipe review at Scent of Green Bananas.
The recipe can be found on this message board posting - look about halfway down the page, or do a search on Boulud.
