An Auckland social enterprise is attempting to break a Guinness World Record today, using 500 kilograms of flour, and 13,000 eggs.

It's an attempt to make the world's largest Lamington cake.

Assembling the 2,500 kilo treat has already begun at Sylvia Park Shopping Centre.

Cook's Night Off founder Suzanne Cannell told Kate Hawkesby they want to beat Australia's record for a Lamington, of 2.3 tonnes.

"We just layer it up one layer at a time, cover it up with chocolate sauce and coconut so it's sticky and gooey, and just build it until we reach that magic number."

Cannell says people are welcome to try the finished result after the official weigh-in around 4pm.

"People can eat as much as they like for a gold coin donation, and the leftovers will be donated to Auckland City Mission."
