I made this cake for my wedding and received so many compliments. It was quite simple to make -- I made one cake two days before the wedding, two the day before and I iced it on my wedding morning! No one could believe I had done it myself, it looked and tasted so good. I actually made 4 cakes and the same quantity of icing worked. As I made the cakes at separate times, I only used one cake tin. We had 100 guests and there was still cake left over, although we had a dessert as well. I used Cointreu (orange liqueur) instead of Grand Marnier. Ingredients for cake are for one cake, so will need to be multiplied by how many cakes you are going to make. The frosting is for three cakes (or more even).
