Dairy Queen broke a Guinness World Record in downtown Toronto on Tuesday, by unveiling the largest ice cream cake ever made.

A large crowd gathered at Yonge and Dundas square as onlookers were offered large pieces of the cake, which weighed over 10 tonnes.

The cake contained 20,000 pounds (9071 kilograms) of ice cream, 200 lbs (90.7 kg) of sponge cake, and was topped with 300 lbs (136 kg) of a cookie crumble and icing topping. The cake took a total of 14 hours to make.

"After 30 years and 52 million cakes, we thought that building a 10-tonne cake would be a great challenge for our team and would help us raise ‘tonnes' of money for Children's Miracle Network and The Hospital for Sick Children. It took nearly 100 people over a year to plan for this record attempt, and we couldn't be happier with the result," said Denise Hutton, vice president of marketing at Dairy Queen Canada, in a recent statement.

Peter White, the executive vice president of operations at Dairy Queen Canada, said "We've been working around the clock to get the cake finished and now to see so many people enjoying a Dairy Queen treat on a gorgeous spring day while supporting our favourite charity, the work has all been worth it."

The previous world record was set in 2006 in Beijing with a cake that weighed just over 17,000 lbs (7,711 kg).
