Mexico has long been known for tacos and tequila — but cheesecake?

Chef Miguel Angel Quezada says 55 cooks spent 60 hours making the world's biggest cheesecake — a 2-tonne calorie bomb topped with strawberries.

The monster cake used nearly a ton of cream cheese, the same amount of yogurt, 350 kilograms of pastry, 250 kilograms of sugar and 150 kilograms of butter.

Carlos Martinez of Guinness World Records declared the cheesecake the world's largest on Sunday at an event sponsored by Kraft Foods, maker of Philadelphia cream cheese.

There wasn't much competition. Guinness had no previous record for cheesecakes. Organizers gave out 20,000 slices around Mexico City.
