This was a very tasty cake. The only change I made was that I used hard pear cider instead of the Guinness, as I didn't have any. The cake was very tender, and had great ginger/molasses flavor. Iced with vanilla icing, and topped with crumbled gingersnaps!
This recipe is fantastic. One of the few that I follow exactly. The only change i've ever made is adding a bit of cardamom (the dutch-indonesian SO appreciates that). This has become the dish I bring to most holiday parties and it's a huge hit. Its even great with a warm blackberry sauce on top for some variation. Thank you for posting this.
