Take Out Second Mortgage for This Chocolate

3. La Madeline au Truffle by Knipschildt: This Connecticut-based chocolatier makes a truffle so expensive that it must be ordered in advance. The Madeline, made with a ganache of 70% cacao Valrhona chocolate, fresh cream, vanilla pods and truffle oil, all wrapped around a French Perigold truffle and dusted with cocoa powder, may very well be the world's most expensive truffle. Each truffle comes with a serial number and a card, personally signed by founder Fritz Knipschildt. They're sold for $250 each, making them about $2,600 a pound.

2. Cadbury's Special Edition Wispa Gold: This chocolate bar enjoyed an eight-year run that ended in 2003. However, a recent Facebook group called "Bring back Cadbury's Wispa Gold" caused enough of a stir, with its 22,000 members, to prompt Cadbury(CBY) to re-launch the bar. The event is being marked with a special-edition bar, which is essentially the standard Wispa Gold, a caramel-filled, milk-chocolate bar covered in edible gold leaf and wrapped in a gold leaf wrapper. The price is exactly 961.48 British pounds, or about $1,568.

1. Serendipity 3's Frrrozen Haute Chocolate: Only in New York can you find the world's most expensive chocolate dessert. About two years ago, Stephen Bruce unleashed the Frrrozen Haute Chocolate, a sundae infused with 5 grams of 23-karat edible gold, a blend of 28 cocoas, 14 of which are the most expensive and exotic from around the world, topped with whipped cream and more edible gold. It's served in a crystal goblet lined with edible gold, an 18-karat gold bracelet with 1 carat of diamonds at the base, and eaten with a golden spoon embedded with white and chocolate-colored diamonds. The diamonds are meant to be taken home. The dessert is served with a Madeline truffle from Knipschildt on the side. It's yours for $25,000.
