If your breadmaker loaf rises well during baking but sinks in the centre afterwards, it usually means the dough has risen too quickly, is too soft, or the structure hasn’t set properly during baking. This can be frustrating, but with a few adjustments, you can prevent collapse and enjoy a perfectly shaped loaf every time.
Common Causes of Bread Collapsing
1. Too Much Yeast
Excess yeast causes dough to rise too rapidly, creating a weak structure that can collapse during baking.
Solution: Measure yeast carefully according to the recipe and always check that it’s fresh. For enriched or sweet breads, consider slightly reducing the yeast if using rapid programmes.
2. Too Much Liquid
Overly wet dough cannot hold its shape and may sink in the centre.
Solution: Check the dough after 5 minutes of kneading. It should form a soft, smooth ball — not a sticky batter. Adjust liquids gradually, 1 tablespoon at a time, if needed.
3. Sugar or Enriched Ingredients
Sugar, eggs, butter, or additions like fruit and chocolate chips feed the yeast and speed up rising, sometimes causing collapse.
Solution: Follow the recipe exactly and add extras at the recommended “add-in” stage (usually after the first knead).
4. Warm Environment or High Humidity
Very warm kitchens or high humidity can accelerate yeast activity, leading to overproofing and soft dough.
Solution: Place your breadmaker in a cooler part of the kitchen. In humid conditions, slightly reduce liquids; in cold environments, ensure liquids are at room temperature (21–28°C).
5. Incorrect Programme or Loaf Size
Using the wrong programme or loaf size setting can result in uneven baking, leaving the centre undercooked or collapsing.
Solution: Choose the correct programme for your recipe — Basic, Wholemeal, or Rapid — and select the right loaf size.
6. Overproofing or Under-Kneading
If the dough is left to rise too long or hasn’t developed enough gluten, the loaf may collapse.
Solution: Stick to the programme times and check dough consistency during kneading — it should be elastic and slightly springy.
How to Prevent Bread from Collapsing
✔ Measure all ingredients precisely
✔ Use the correct type and amount of yeast and flour
✔ Ensure the dough forms a smooth, elastic ball during kneading
✔ Avoid opening the lid during rising
✔ Select the correct programme and loaf size
✔ Adjust for kitchen temperature and humidity if needed
✔ Add enriched ingredients only at the recommended stage
When Slight Collapse Is Normal
Some breads may sink slightly in the centre without affecting taste or quality. These include:
Sweet breads with fruit, chocolate, or nuts
Wholemeal or multigrain loaves
Small loaves baked on rapid programmes
Even in these cases, the bread should not be heavy, doughy, or undercooked.

✅ Pro tip: Always let your loaf cool slightly before slicing. Removing bread too early can affect the crumb structure and make it appear denser.
