If you are at Book Expo and need a a little sugar pick-me-up, there is a van parked outside offering treats sweeter than the typical Javitz food truck fare.

Penguin Young Readers Group has stationed the Dessen Sweetery Truck, dedicated to author Sarah Dessen and it’s worth dropping by for a tasty snack. They are giving away three flavors of whoopee pies: red velvet, chocolate, and Sarah’s Strawberry Surprise.

The author is at the show promoting her new book What Happened To Goodbye and may hand you one herself.

Catch it today, because according to GalleyCat, it moves to Union Square tomorrow.
