Oven temperature is one of the easiest chiffon cake variables to misunderstand. The dial setting is not always the real temperature around the pan.
When failures repeat, verify heat before changing the recipe. A small temperature or rack-position difference can change rise, cracks, shrinkage, and center texture.
Quick diagnosis
- Top cracks too early: Top heat may be too strong or the rack may be too high.
- Dense or wet center: The cake may need longer baking or more stable heat.
- Concave bottom: Bottom heat and early structure setting need attention.
Likely causes
The oven may run hotter or cooler than the setting. Preheating may not be complete. The pan may sit too close to the top or bottom heat source.
Opening the door early can also drop temperature before the cake structure has set.
Quick test
Use an oven thermometer and bake the same recipe on the same rack. Record the real temperature after preheating and during the first half of baking.
Next-bake fixes
- Preheat fully before the batter is ready.
- Use the same rack position for comparison bakes.
- Avoid opening the door early.
- Adjust temperature only after confirming the real oven temperature.
