For Halloween this year I made a cauldron cake with tea lights behind a fence of fire and dry ice for the boiling effect. All best observed in the video below. I made a small pocket at the top of the cake to fit a small shot glass for the dry ice. It was a simple cake but the effects made it a lot more fun.
It was a decadent almond cake with cannoli filling. The little tentacles trying to escape the boiling are more cute than scary Halloween.
