If you thought the Serpentine Goblets were pricey, then let me introduce you to the world's most expensive dessert: Frrrozen Haute Chocolate. Created by the folks at the Serendipity 3 restaurant in NY, the Frrrozen Haute Chocolate — which is an expensive version of their famous Frrrozen Hot Chocolate — rings up at $25,000. Yes, that is a five figure price tag on a single dessert.

The dessert itself is a mix of cocoa and milk, frozen to a slush-like drink. Five grams of 24-carat gold is mixed in and then it's topped with more gold and garnished with a $250 chocolate truffle that is flown in from France.

The dessert has just gone on sale and actually needs a two week lead time (they also fly the gold in from Switzerland). So far they haven't sold any, but I'm sure that's just a matter of time.
