Aang takes an experimental bite from one end of the dessert, and chews thoughtfully. When it's been decided that the treat is as delicious as it looks, he takes a larger bite.

Unfortunately this larger bite comes with a bit more powdered sugar than Aang was expecting. Or...really it's Aang's nose that was surprised. Before he can give anyone a proper warning, he sneezes.

Now...when an airbender sneezes, he really sneezes. He flies about ten feet back, slamming hard into the booth behind him, while at the same time sending out a powerful blast of air from his nose and mouth that knocks over just about anything within twenty feet in front of him.
