Why Did My Bread Collapse During Proofing Or Baking?

Bread baking is a time-honored tradition that has been practiced for centuries, producing warm, fragrant loaves that are as delicious as they are satisfying. However, even the most experienced bakers can experience the frustration of a collapsed loaf of bread. 

Whether you’re a novice or an experienced bread baker, if you’ve ever asked yourself, “why did my bread collapse during proofing or baking?” you know how disappointing it can be. 

Several factors can contribute to a bread collapse, from using the wrong flour to over-proofing the dough, and understanding the causes can help you avoid the problem in the future. 

In this article, we’ll explore the possible reasons why your bread might have collapsed and offer some expert advice on how to achieve perfectly risen, beautifully fragrant loaves every time. 

So, whether you’re a bread-baking enthusiast or just looking to improve your skills, read on to discover the secrets to avoiding bread collapses and achieving perfect loaves every time.

8 Reasons Why Your Bread Collapses

The recipe is followed, and the dough is gently cared for, but once the oven is opened, you find that your expectations have been shattered. 

It’s a common problem that can be easily fixed once you identify it. Let’s discuss the reasons so that you might find one that suits your situation.

1. There Is Too Much Water in Your Dough

The most common cause of a bread loaf collapsing is too much water in the dough. To create a strong gluten mesh, flour needs to be well-hydrated.

However, having too much water in your dough can cause the bread to collapse during cooling. In particular, quick bread recipes require a dryer dough to avoid shrinkage when cooled since quick loaves of bread are made quickly.

Try adjusting the recipe for next time if the dough is too wet, or you could try baking the bread for longer to remove some of that moisture.

2. Old Dry Ingredients

A key ingredient in bread dough is yeast; if your bread is crumbling, the culprit might be your yeast.

You may need to replace it if it is too old. The yeast is a living organism that could expire if it is left too long. It is best to test your yeast before mixing any ingredients together.

You can do this by adding yeast to warm water along with some sugar, as specified in the recipe. Several minutes later, live yeast will begin eating the sugar, and foamy bubbles will appear at the surface. In case nothing happens after 10 minutes, purchase a new pack.

3. Problems With The Yeast In Your Dough

Using too little yeast in your dough mixture could also be an issue. When your bread dough doesn’t have enough yeast, it will take a lot longer to prove since the yeast needs time to create the gluten mesh that makes it rise.

Your bread will collapse in the oven or after you take it out if you use too little yeast and don’t give it enough proofing time.

4. The Proof Is In The Pudding

Proofing your bread dough before baking is important, regardless of which bread recipe you use. If you are making a specific type of bread, you must make sure that you proof the dough for the appropriate amount of time.

The yeast consumes the starch in the flour to produce carbon dioxide and alcohol in the dough as the gluten develops. This gluten development process needs time.

In order for a dough to be able to rise, it needs to be kneaded and proofed, and too little of either will result in it sinking.

Time and temperature are crucial factors when proofing your dough. Your dough will take longer to proof if your kitchen temperature is low. Conversely, proofing takes less time in a warmer environment.

When the dough sits too long, all of the starch will have been consumed by the yeast, and the dough will no longer rise and collapse in on itself.

It is ideal to proof dough between 24 and 36C (70-115F) and generally no longer than two hours for the first proofing and one hour for the second. However, the dough is ready to use if it has doubled before these times.

5. Baking Temperature

Each oven has its own quirks, and you need to learn what yours are. Some ovens run hotter than they are set to, and some run cooler.

Overheated ovens result in brown, crispy outer crusts but doughy interiors that collapse during cooling. Low oven temperatures prevent the bread from rising, resulting in dense, sunken loaves.

You may need to experiment if you suspect your oven is not working properly. You can test your thermostat’s accuracy using an oven thermometer, or you can adjust the knob a few degrees higher or lower for your loaf and see whether it works.

There are no substitutes for good ingredients, and even the best equipment and techniques will not make a great loaf.

6. You Over-Proofed Your Bread Dough

You may have over-proofed your dough if it collapses when you cut it or transfer it from the proofing basket to the pan or bread maker.

Generally, it indicates that the bread dough has been over-proofed. Your bread dough is most susceptible to collapsing during the proofing stage before baking.

As your bread bakes, an over-proofed dough will collapse or flatten. Your bread dough has collapsed because the yeast has run out of energy to continue rising while it bakes.

Additionally, the dough cannot rise anymore due to its excessive expansion, so when you place it in the oven, the yeast cannot produce more gasses to assist the dough, and the dough collapses.

You are more likely to encounter this problem if your bread recipe is complicated since you can easily misjudge the proofing time.

You can prevent this by holding strictly to the time specified in your bread recipes and setting a timer.

7. Mishandling Of The Dough Can Collapse It

Sometimes, when you transfer your loaf of bread from one place to another, you will notice that it collapses or flattens. Ciabatta bread dough, for instance, has a high hydration level, making it particularly prone to breakdown.

These types of doughs are very fragile due to their gluten mesh, so you need to be very gentle when handling them.

Using too much force when you knead your dough can cause it to break the fragile gluten mesh and allow gases to escape. This will cause your bread dough to collapse before it is baked or during baking.

Be gentle when handling your bread dough in any way in order to avoid this problem. Although bread dough is generally forgiving, all bread dough can be damaged in this way if you are not careful.

No matter the bread you are making, always use a gentle touch with your dough and use a bench scraper when moving it to avoid putting any pressure on it.

8. You Did Not Knead Your Bread Dough Enough

It is important not to skip or shorten the kneading time when making bread in order to save time. You can obtain a rising dough by kneading your dough after it has been proofed for the right amount of time, which creates a gluten mesh that allows your dough to rise once it is baked.

If this gluten mesh is not sufficiently developed because you did not knead your bread dough long enough, the bread dough will quickly rise but collapse once it is handled after proofing.

The gluten mesh in the dough isn’t strong enough to hold the gases after proofing. Although your dough collapses before you bake your bread, you will notice it once the gases escape from the dough and the bread flattens out during baking.

You can fix this problem by kneading your dough for the proper time and using the right method. A simple test can also tell you if your dough’s gluten mesh is strong enough or if it needs more kneading.

It is known as the windowpane test, and you conduct it by stretching a small piece of your bread dough between your fingers. It’s a sign of a good gluten mesh if you can see the light coming through it, and the dough doesn’t break.

Why Your Sourdough Collapsed In The First Place?

You generally spend more time on sourdough than on regular yeast-risen bread, so having it collapse is much more disappointing.

Regular bread and sourdough bread are only distinguished by the type of yeast used. While regular bread uses dried or fresh yeast, sourdough is made from a homemade yeast culture and lactic acid.

It can be very disappointing to have your bread collapse on you, since it takes time to make a good loaf of bread. As a result, you may wonder what happened to your bread and why it collapsed.

In most cases, bread collapses as a result of being over-proofed. It means the yeast has consumed all of the sugars and starches in the dough and, therefore, cannot produce carbon dioxide anymore. 

Unless the dough is continuously producing gas, it will collapse. It would help if you didn’t assume that this is the only cause of bread collapsing. While this is the most common reason, numerous other mistakes can cause it to collapse. 

More Tips to Help Stop Your Bread Collapsing

In case you’ve checked all the issues mentioned above and are still having trouble with your bread collapsing, consider these extra factors that may prevent your bread from collapsing in the future.

  • Your bread’s rise depends on how you shape the dough, so ensure you do it correctly. Using a loaf tin will prevent it from collapsing if you don’t shape it well.
  • Try different flours since some flours support bread’s structure better than others.
  • When making bread dough, be sure to use a suitable amount of flour since yeast requires flour to rise.
  • You should be careful when scoring your bread; if you are too rough, your bread may collapse.
  • You should include a slat in your bread dough recipe, as your bread will collapse without it.
  • You should never add salt directly to your yeast when making bread dough, as this can kill it.


In conclusion, bread baking is both an art and a science. It requires precision, patience, and a willingness to learn from mistakes. Keep going even if your bread has collapsed during proofing or baking.

Instead, use this experience as an opportunity to improve your bread-making skills. Take note of the factors that may have caused the collapse, such as over-proofing, insufficient gluten development, or incorrect oven temperature.

With practice and experimentation, you can overcome these challenges and bake perfectly risen, delicious, and satisfying bread. So, keep baking, keep learning, and keep enjoying the delicious results of your hard work!
