I am doing a cake ball cake for a wedding this weekend. It is 3 tiers with cake balls covering each of the cakes. I have never made one and I am feeling indecisive about if I should assemble the cake and then drive it 45 minutes or assemble it there. I am reluctant to do both. My question is for those who have done a cake ball cake, Did they stay in the cake pretty well? I hate to try to do it on location but I am afraid they will fall out when I am driving. Any suggestions?
