Starbucks seems determined to outdo itself with ever more outrageous frappuccino concoctions. Its latest? The Double Double Fudge Bar Frappuccino, which the coffee chain bills as “a stop-you-in-your-tracks avalanche of fudgy goodness.” In reality, the ice-blended drink is basically a chocolate milkshake with some coffee, with a double helping of mocha sauce — topped with chocolate whipped cream. This isn’t so much a caffeine hit as a guaranteed sugar rush.

Starbucks says the drink will run chocoholics about 460 calories a pop and will be available for a limited time as an official menu item. (Of course, it should be easy enough to order off-menu given the simple enough ingredients.) It’s getting good reviews from those who’ve tried it so far, too.
