When you are picking up a cake, PLEASE make sure that you have plenty of room in your car to transport your cake. I usually am unable to provide a box to place your cake in due to the size and shape of most of the custom cakes that I make. It also allows me to keep the cost of my cakes lower. All of the cakes that I make are placed on a cake board. There has never been a problem that I am aware of with a cake sliding off the board or being damaged in transport but be advised that I highly recommend that you bring a passenger that can help by holding the cake or keep it in a clean secure spot in your car.
