This is the largest cake I've ever made. Base is 4 - 12x18, 2 are chocolate/2 are white, 8" single layers on pillars. All BC. Project for DD goverment class-had to predict the electorial votes for 04 election and give the most unique presentation. DD did all the baking, I did most of the decorating. DH had to make a cake board of 3/4" plywood just to hold the cake. It took two of us to carry into the high school. Was enough cake to feed the whole school.
