Donald Trump is known for throwing lavish parties, but at the birthday bash he threw for Ann Romney today, it was the birthday cake that stole the show.

The cake, created by celebrity chef Buddy Valastro, of the TV show "Cake Boss," is topped with a sugar-coated Romney riding atop a horse standing in a field of green frosting. Romney is an avid horseback rider and often goes riding to soothe the symptoms of her multiple sclerosis.

The lifelike equestrian cake was showcased at Romney's 63rd birthday party Tuesday afternoon at Donald and Melania Trump's New York City home, on the 66th floor of the Trump tower. About 400 people were slated to attend the birthday party-turned-fundraiser, which a Trump spokesman told CBS News is expected to bring in $600,000 for the Romney campaign.
