Celebrate World Chocolate Day by booking in for one of these unbelievably decadent treats. Just try not to drool...

Paying due respect to World Chocolate Day (July 7 for anyone who hasn't hardwired it into their calendar) is an annual burden that every chocoholic must shoulder. Getting through this hardship requires some ground rules, starting with where to get the chocolatey goods.

Because whoever made this day up (the origins of World Chocolate Day are murky at best) would be horrified to learn that you celebrated with nothing but a block of Cadbury. Is that the best you can do? But a dessert plate stacked with rich, velvety chef-baked chocolate cake or a trio of smooth-as-silk chocolate mousses - now we're talking proper respect. 

This special day is really about what you bring to the table, so if you're ready to indulge, scroll through for 17 of the best chocolate desserts on the planet, from Sydney to London and back again. Try not to lick the screen...
