Why cakes sink in the middle? Error Correction Guide

I smell the delicious smell of my favorite cupcakes, it’s time to get it! I open the oven, but instead of lush high cupcakes I see that cakes sink in the middle. Why did it happen so? After all, I did everything exactly as indicated in the recipe.

Before you point the finger at the recipe, keep in mind that a variety of factors can affect the chemistry of your underwhelming cake creation.

Since this is a frequent issue when making cakes, I’ve compiled all of my solutions here to assist you. Let’s discuss the causes of cake sinking and how to prevent it because there are a variety of potential reasons why this could happen.

This article aims to explain why cakes sink in the middle and how to avoid it in the future.

I also offer some advice on how to save cake layers that have sunk.

What happened? Why cakes sink in the middle?

1. The cake is not baked enough

The most frequent cause of a sunken-in middle in a cake is under baking. The cake sinks did not bake for long enough for the texture to be uniformly great. As a result, the cake’s outer border will be baked but its core won’t.

You must use the toothpick test to examine your cake to determine the “correct” cooking time. Enter the cake’s center with a toothpick and remove it. Is it spotless, besides a few crumbs? Let it continue to cook if not.

 How Can You Tell if a Cake Is Done Baking?

  • If it’s a vanilla cake, make sure it’s golden brown.
  • Verify if the sides have slightly separated from the pan.
  • Check that the top isn’t too soft by barely touching it.
  • If the cake jiggles when the oven door is opened, keep an eye on it.
  • Put a toothpick through the cake’s center using this method. Check for cake batter by taking it out. The toothpick doesn’t need to be completely clean; it only has to have a few wet crumbs on it. Simply said, you don’t want any uncooked batter on the toothpick.

2. Excessive oven door opening or forceful door closing

Did you slam the oven door shut or open it too wide? Continually opening the oven door will change the oven temperature.

The heat leaves the oven, and when it is shut again, the oven needs to struggle to reestablish the heat before you open it again immediately away to inspect. Additionally, if you slam the oven door or just shut it too quickly, the cake may be jostled and collapse as a result.

All those lovely little little air bubbles in the batter that have enabled the cake to rise will explode with a quick shake of the pan.

Soon after you slam the oven door, your cake will start to sink.

What to do to stop that?

Take extreme care not to widen the door too much. Try to wait until the cake is about five minutes from completion before checking it. After that, take cautious not to leave the oven door open too long and gently close it when you inspect it.

3. Excessive Leavening Agent

The third potential offender is either using the incorrect type or too much leavening agent. A cake might rise too rapidly and too high if there is too much leavening ingredient, such as baking soda or powder. 

Before the cake bakes through in the middle, the gas from the leavening chemicals builds up and escapes. Your cake’s layers will sink in the center due to the collapse of the core as a result. When using leavening agents, it’s crucial to measure them exactly because a little goes a long way!

To ensure that you are using the appropriate quantity, level the spoon’s top with a knife or the top of a box at all times. It may sound ridiculous, but it’s crucial to use the proper leavening agent while baking.

They cannot be used interchangeably since baking soda is nearly three times as strong as baking powder.

How To Avoid This Happening Again?

A teaspoon or digital scale should be used to measure the precise amount of leavening agents that a recipe asks for.

Additionally, the recipe could not be good! Unfortunately, not all recipes are written properly, and occasionally this can also be the issue.

You might want to try a different recipe if after several attempts at a particular recipe your cake is still sinking in the middle.

4. Your oven is overheated

Have you ever tested the temperature of your internal oven? Your oven’s display may occasionally show one oven temperature even when the inside is actually warmer.

An overheated oven may cause the cake to rise too quickly and subsequently sink throughout the remaining baking time.

In most cases, the final cake will have overbaked borders and a runny center. If you’re ever unsure of your oven temperature, you may buy a thermometer to put inside the oven to make sure it’s set at the proper temperature.

How To Avoid This The Next Time?

Using an oven thermometer, check the temperature in your oven.

If your oven is too cold, turn it up to the recommended temperature so that baking will take place at that level. Alternately, lower it if necessary if your oven is too hot.

5. Use a different pan size

The baking time needed can be significantly altered by using a pan size other than what a recipe specifies. It may result in your cake layers being either thicker or much thinner than the recipe calls for.

How To Avoid This Happening Again?

If you need to bake cake layers that are bigger than what a recipe specifies, it’s best to use your trusty molds or keep a close eye on the cake in the oven. If your shape is wider than in the recipe, the cake will bake faster.

As a result, the layers bake more rapidly and evenly because they are better able to transfer heat to the layer’s interior.

6. You’re mishandling the mixing

When putting your cake batter together and mixing it, keep the following points in mind:

  • Don’t over-cream the butter and sugar

Creaming is crucial to produce the gas bubbles that give the cake its fluffy texture and beautiful rise. A sunken center might result from over-creaming, which can release the gas bubbles or force them to work too rapidly.

  • Avoid over-mixing as wellJust as detrimental to your cake as over-creaming is over-mixing

Over-mixing introduces too much air into the batter, causing the cake to rise quickly before falling. It can also make the texture more thick all around.

  • Avoid using butter that is too soft butter

While I can understand the need to rapidly reheat butter in the microwave, doing so can have more negative effects than positive ones. The butter shouldn’t be too soft. Ideal temperature is 68 F.

  • There is a reason why cake recipes are broken down into steps

Mix the ingredients in the proper sequence. Never attempt to skip a step and return to it later. If you don’t follow the directions to the letter, your cake can end up sunken.

  • Avoid letting the mixture sit for too long

This is strictly forbidden in the cake-baking industry. To prevent potential catastrophes, put the batter in the preheated oven as soon as it is combined and ready to go.

7. You’re using expired baking powder

One of the elements that contributes to the gorgeous rise of your cake is baking powder.

Baking powder has a shelf life of between six months and a year, in contrast to baking soda, which almost never goes bad.

It’s very sensitive to humidity and moisture, so you need to take care to store it properly in a cool, dry pantry if you want to keep it for as long as possible.

How To Avoid This Happening Again?

In order to keep track of when a fresh can of baking powder expires, I always write the date that I opened it on the lid. You may test your baking powder by putting 12 a teaspoon in a cup and adding 14 cup of boiling water if you’re unsure how long it’s been.

It’s still excellent if it quickly bubbles up. In that case, you should get a new tin before baking a cake recipe. Unfortunately, if baking powder is over its expiration date, no chemical reaction can take place for a cake to rise.

8. The recipe is just unreliable

The internet is filled with a ton of cake recipe, and surprise, not all of them are written correctly or undergo thorough testing. Too much liquid in the recipe, the wrong amount of leavening agent, or other incorrectly measured components are some typical causes of cakes sinking.

All of my cake recipe are extensively tested before being published for public consumption since recipe authoring needs a lot of testing, but not all bloggers have the time (or desire) for

It takes experimenting with a few different cake recipe to find the one you adore. I’m confident you’ll produce a cake you adore as long as you pay attention to the precise directions and take some time to compare!

Frequently Asked Questions

I will please you: you can save the cake sink in the middle, but only it must be baked.

What can I do with a cake that’s sunk?

Option 1. The simplest and quickest solution is to level the cake layer.

This gives you the opportunity to chop out the under-baked or raw area, leaving you with a flat cake layer. This only functions, though, if the center barely slightly sinks.

Option 2. Re-place in the oven

You can put your cake back in the oven for a few minutes if you notice that the center sinks right after you remove it from the oven. While the sunken center won’t be truly fixed, the uncooked center will be helped to bake through.

Option 3. Assemble the cake with additional buttercream.

If all else fails, you may just cut off the undercooked areas of the cake and fill it in with a little additional frosting. I think that anything can be fixed with buttercream.

Option 4. Option 4. Simply removing the center entirely with a circular cookie cutter

You can fill with any candies with cookies, fruits or delicious cream

Option 5. Make cakes and sweets

If the middle is not very raw then from a few moist crumbs you can make cake pops for children, dip in chocolate and sprinkle with crumbs.

A cake that has sunk in the middle—can I still eat it?

Sunken cake can be edible. To begin with, make sure the cake has finished baking. Next, examine the cake’s texture. Try it on a small area or a piece first. The texture could be excessively thick or rubbery.

This is evident, but it would not taste nice if an ingredient was omitted or if too much baking soda was used. After determining all of these factors, if the cake has a decent texture, is fully cooked, and tastes well, you’re set to go.

Final Remarks

Both the appearance and taste of a sunken-in cakes sink will likely be poor. The good news is that the reasons of sunken-in cakes are usually easy to remedy, such as managing the batter properly and correctly following the recipe, and when the cake sink in the center, it may still be saved.

All lush and delicious cupcakes!
