(I posted earlier this week about this- converting a recipe from cupcakes to a layer cake.)
My husband's birthday is this weekend so I decided to make him a Guinness chocolate cake w/cream cheese icing from a Dave Lieberman recipe I found in a beer magazine.
I made it last night (for tonight) and I snuck a bite from some trimming. It is delicious. The texture is somewhat dense but melts in your mouth, and the Guinness really enhances the chocolate flavor (I used Ghirardelli cocoa which probably helped). The icing is a perfect complement.
I promise to post the recipe soon, but if you have Draft magazine or Dave Lieberman's book it's in there.
