The sundae costs $3,333.33 and consists of a banana split made with syrups from three rare dessert wines, served with an ice cream spoon from the 1850s. If you give them a day’s notice, they’ll even have a cellist play while you eat it (1/3 of the price is being donated to a local land trust).

If its not expensive enough, then perhaps the $60,000 “World’s More Expensive Most Expensive Ice Cream Sundae” will pique your interest.
For $60,000 you can travel to the summit of Mount Kilimanjaro, where the Three Twins Ice Cream founder will handchurn a batch of ice cream using the glacial ice found at the summit.
The cost includes first class airfare to Tanzania, five-star accommodations, a guided climb, all the ice cream you can eat, and an organic T-shirt.
It should also be noted that a portion of the purchase will go to an African environmental nonprofit.
