Here's Paul Joachim's 80 oz. monster cake from 2007, as featured on Evil Cakes:
Made for a halloween party, this cake came out quite scary and realistic! I used 4 deliciously moist chocolate cakes along with a TON of ganache, 80 ounces of chocolate and 8 cups of heavy cream to be exact ;) The engineering on this wasn’t easy considering how thin the neck is. It really held up well! The head is a 3 layer cake. There are NO dowels, NO rice krispies for this cake.
