Lambeth Cake Preparation Time: 2 Weeks This very popular cake is decorated in traditional Lambeth style, with butter chocolate ganache shells piped at the bottom and top edge of the cake and then adorned with more delicate buttercream swirls all around. It is available to order in a round or heart shape in any colour/s you like (feel free to state your preference in the comments box). Customise further by adding a name or age which is either handwritten or stamped into a colour coordinated fondant and placed on top or side of the cake. NEW LUXURY FILLINGS! This 7 inch cake offers a selection of luxury fillings and is big enough to give at least 16 slices if cut correctly. It is covered in butter chocolate ganache.
