• Guinness Gingerbread dessert

  By all accounts and reviews, this recipe sounds absolutely delicious and I am going to attempt it as soon I get the ingredients. However, I would like to ask if this cake is moist enough to serve hot as a pudding with custard or cream, and secondly could I substitute buttermilk for the sour cream? Many thanks for a lovely website. Softique

  I made this cake last night as the first thing I have made from the book and am very disappointed with the result. The cake is extremely heavy and doughy - not pleasant at all. I did have to cook it for longer than the recipe said - probably about 10 minutes longer but I tested with a skewer and it came out clean. There were quite a lot of ingredients and I feel I want to throw it away. Have a regular ginger cake recipe I use which never goes wrong - so a real shame. Lester27
