Nigella's coffee and walnut layer cake. Rose like a dream and stayed moist for days. I actually used the cake recipe to make about a dozen cappuccino cupcakes- just topped them with white chocolate frosting (lovely recipe pinned on my board) and sprinkled them with dark drinking chocolate. Heaven!
White Chocolate Espresso Cake - I made up the mix as per the recipe and then poured the mixture into a muffin tray instead. I made 12 muffins, and then cut each into three and put them together with the icing in the same way suggested.
