Guinness World Records adjudicator Danny Girton Jr. called it a "fun and creative achievement."
The cupcake was made by cakes.com, which is run by cake-decoration supplier and marketer DecoPac.
Company spokeswoman Jamie Miller said the giant cupcake will go to a pig farm. The company decided against giving away pieces to mall patrons because most would not have had frosting.
Instead, cakes.com gave away 4,000 smaller cupcakes.
