a tip for transporting cakes – I always make sure that the cake is snug in the cake box by putting a rubber none slip mat under the cake board, I then also use a rubber non slip mat under the cake box and I always transport my cake in the boot of the car with nothing else in the boot but the cake, and may be further boxes next to the cake box if worried – you can pick the mats up from amazon & ebay
