A chiffon cake that falls out of the pan during cooling loses the wall support it needs. This usually points to pan surface, overbaking, or structure problems.
It is different from normal unmolding. The cake should release after cooling when you loosen it, not drop before it is ready.
Quick diagnosis
If the cake falls while still warm, the sides did not grip the pan. Check greasing, pan coating, excessive side shrinkage, and whether the cake was overbaked around the edge.
- Falls immediately: Check greased or nonstick pan walls.
- Falls after shrinking: Check overbaking and weak structure.
- Falls with wet center: Check underbaking as well.
Likely causes
The pan wall is part of the support system for chiffon cake.
- Greased pan: The cake cannot cling during cooling.
- Nonstick surface: The wall may be too slippery.
- Overbaked edge: The cake contracts and releases early.
Quick test
Use a clean ungreased aluminum tube pan and cool it upside down immediately. If the cake stays attached, the old pan surface was likely the issue.
Next-bake fixes
Prioritize grip and balanced baking.
- Do not grease the tube pan.
- Avoid slick nonstick pans for classic chiffon cake.
- Check whether the edge is drying too much.
- Cool fully before loosening the sides.
