Princess Diana's Wedding Cake Up For Auction

Not everything improves with age. Cheese and wine, sure. But cake is not normally on that list, unless it's a super-special fancy cake like the royal wedding cakes being auctioned off next month by Julien's Auctions.

According to The Huffington Post, The Beverly Hills, Calif.-based auction house is selling two slices of royal wedding cake as part of its "Icons and Idols" auction on November 9 and 10. One slice is from the recent wedding of Prince William and Kate Middleton. The other slice is from the 1981 wedding of Prince Charles and Princess Diana.

While we can't say for certain what makes an old cake desirable, the auction catalog estimates that the 31-year-old Princess Diana cake, which is of unspecified flavor, will be twice as desirable as Kate Middleton's brandy-infused fruit cake from 2011. Diana's cake is estimated to bring in $1,000-2000, while Kate's cake is only expected to bring $600-800.

In the case of Princess Diana and Prince Charles' cake, the auction house specifies, "The cake is not suitable for consumption," because you just know someone would have tried to eat the thing.

Prince William and Kate Middleton's cake carries no such caveat, but we recommend trying out one of our best fruitcake recipes instead.
