traveling with a cake-
Great care is taken in the construction of your cake. If your creation is to be driven more than 10-15 minutes, you may want to consider a non-tiered cake or bring someone with you to hold the cake. The best place for a cake to travel is on the front passenger floor board with something tucked under it if necessary to make it level. If the temperature is above 70degrees, you will want the have the AC on.
Square and rectangular cake are fairly straightforward to cut, while ruond cakes are slightly more complex. A serving size should measure 1"x2"x4" for layer cakes and 2"x2"x2" for sheet cakes. To serve a tiered cake, slide a spatula under the board to move each tier over to a separate plate. Remove all supports before cutting.
