Uneven rise can make one side tall while the other side stays low or collapses. The cause may be oven heat, batter distribution, or pan position.
Do not judge the cake by height alone. Check whether the crumb is even, whether the top cracked on one side, and whether the pan sat level in the oven.
Quick diagnosis
If the high side faces the hotter side of the oven, heat imbalance is likely. If the crumb has streaks or large holes, batter distribution and folding may be more important.
- One side high: Check oven hot spots and pan level.
- One side cracked: Check top heat and rack position.
- Uneven holes: Check pouring and final batter consistency.
Likely causes
Uneven rise usually starts before the cake is fully set.
- Hot spot: One side expands faster than the rest.
- Uneven pour: Heavy batter gathers in one area.
- Tilted pan: The batter layer is deeper on one side.
Quick test
Bake the same recipe with the pan centered and level, then rotate only if your oven and recipe tolerate it after the structure has set. If the high side changes direction, the oven is the clue.
Next-bake fixes
Start with placement before changing the formula.
- Confirm the oven rack is level.
- Pour batter evenly around the tube.
- Tap lightly only to settle very large pockets.
- Record which side faces the oven door or fan.
