How do we know when a chiffon cake is properly baked?

In this video, I have baked one successful chiffon cake along with four failed ones, experiencing a variety of overbaked and underbaked disasters along the way. If your chiffon cake shrinks when taken out of the oven, peels at the touch, or falls out once flipped, this video will solve your problems. A perfectly baked chiffon cake exudes a richly baked fragrance. Trust me, after eating it once, you’ll fall in love with it.
