After saying "I do" on Saturday night, Kim Kardashian and Kris Humphries cut into a seven-tier wedding cake that cost more than most couples' entire wedding.

The five-foot-plus tower was made of white cake and chocolate chip filling -- that's chocolate buttercream frosting with chocolate chips added -- then iced in black and white buttercream. For her big day, the reality star hired Hansen's Cakes, a Los Angeles-based bakery where the Kardashians are regular clients.

Monique Hansen, the bakery owner's sister and a Hansen's employee, says that if a customer ordered a similar cake, it would go for $15,000 or more. Kim and Kris visited Hansen's in late July for a tasting, but Kim's choice wasn't a surprise. White cake with chocolate chip filling is Kim's favorite, Hansen says.

"I think that's the only cake she eats," Hansen says. "The family has had an account with us for a long time."

The tiers were different shapes, including circles and octagons, Hansen says, and were decorated in white and black buttercream icing using the Lambeth method, a very traditional method of piping, with swirls, French curves and swag.

Sure, it looked incredibly fancy, but the cake itself was a Hansen's classic.

"It's what we call our 'bridal white,'" Hansen explains. "It's an old family recipe. It came out of great-grandpa's recipe book."

Four people worked on the cake over a few days, but the most difficult part was transporting the cake to the wedding in Montecito, California, Hansen says. It was chauffeured in two vans, then assembled on site.

Kim and Kris reportedly cut into the bottom tier during the ceremony, but not all guests got to sample from the tower.

"To make sure that everyone got enough, we did send some additional sheet cakes," Hansen says.
