In honor of Italian chef Mama Maria's 101st birthday, Brittnee Klinger re-creates an Italian feast that's so realistic the chef can't tell the difference between the cake and her own food! Kristen LoVullo makes a gravity-defying Irish whiskey bottle that looks like it's pouring a stiff drink. Then, the team crafts a massive 500-pound pot of gold cake complete with a leprechaun and a secret chamber of gold coins for the biggest St. Patrick's Day party in Las Vegas.
