If you love making quick bread, but find yourself struggling with the middle sinking in, don’t despair. Sinking in the middle is a common problem that can happen to anyone. In this guide, we will explain the science behind quick bread baking, go over the common reasons why quick breads sink in the middle, and provide helpful tips to troubleshoot the problem.

Understanding the Science behind Quick Bread Baking

Quick breads are a type of bread that is leavened with baking powder or baking soda, rather than yeast. When the baking powder or baking soda is mixed with the other ingredients and moistened, a chemical reaction happens that produces carbon dioxide gas, which causes the bread to rise. The carbon dioxide gas expands the air pockets in the batter, creating small bubbles which make the bread light and fluffy.

However, if the gas is released or escapes too quickly, or if the structure of the batter is not strong enough to hold the gas, the bread will sink in the middle.

One of the advantages of quick breads is that they can be made quickly and easily, without the need for a long fermentation process. This makes them a popular choice for busy home cooks and bakers. Additionally, quick breads can be made in a variety of flavors and styles, from sweet to savory, and can be customized with different mix-ins and toppings.

It is important to note that while quick breads do not require yeast, they still require careful measuring and mixing of ingredients to ensure that the chemical reaction occurs properly. Overmixing the batter can cause the bread to become tough and dense, while undermixing can result in uneven rising and a dense texture. With the right technique and attention to detail, however, anyone can master the art of quick bread baking.

Common Reasons Why Your Quick Bread is Sinking in the Middle

Uneven Mixing

If you don’t mix the ingredients evenly, your quick bread won’t cook evenly, leading to undercooked centers and sunken middles. Make sure to mix the dry ingredients thoroughly before adding the wet ingredients. Then mix everything together until the batter is smooth and evenly combined.

Too Much Leavening Agent

If you use too much baking powder or baking soda, it will create too much carbon dioxide, causing the bread to rise too quickly and then sink. Make sure to measure your ingredients accurately and use the amount specified in the recipe.

Low Temperature

A low oven temperature can cause the baking powder or baking soda to release most of its gas too early in the baking process, resulting in a sunken center. Make sure to preheat your oven to the correct temperature before adding the batter, and avoid opening the oven door too often during baking.

Wrong Pan Size

If you use the wrong pan size, your quick bread will either be too thick or too thin, creating an uneven cooking experience and risk of sinking in the middle. Use the pan size specified in the recipe to ensure the best outcome.


While uneven mixing can cause sinking in the middle, overmixing can also be a culprit. Overmixing can cause too much gluten to develop, which can lead to a tough and dense bread that sinks in the middle. Mix the batter until just combined, and avoid overmixing.


If you take your quick bread out of the oven too soon, it may not have had enough time to fully cook and set, leading to a sunken center. Make sure to follow the baking time specified in the recipe, and use a toothpick or cake tester to check for doneness before removing from the oven.

How to Measure Ingredients Accurately for Perfect Quick Bread

Measuring ingredients accurately is a key step in making perfect quick bread. Use measuring cups and spoons for dry ingredients and a kitchen scale for wet ingredients. Be sure to level off the ingredients before adding them to the mixing bowl to avoid using too much or too little.

Another important tip for measuring ingredients accurately is to use the correct measuring tool for each ingredient. For example, use a liquid measuring cup for liquids and a dry measuring cup for dry ingredients like flour and sugar. Using the wrong measuring tool can result in inaccurate measurements and affect the texture and taste of your quick bread.

It’s also important to measure ingredients in the correct order. Start with the dry ingredients and then add the wet ingredients. This will ensure that the dry ingredients are evenly distributed and prevent clumping. Additionally, when measuring sticky ingredients like honey or molasses, lightly coat the measuring cup or spoon with cooking spray or oil to make it easier to remove the ingredient and get an accurate measurement.

Choosing the Right Flour for Fluffy and Light Quick Bread

Choosing the right type of flour is essential when making quick bread. Use all-purpose flour or cake flour, which have lower protein content compared to bread flour. This will produce a lighter and fluffier texture.

It’s also important to consider the type of quick bread you’re making when choosing flour. For example, if you’re making banana bread, using whole wheat flour can add a nutty flavor and denser texture. However, if you’re making a delicate lemon poppyseed bread, using all-purpose flour or cake flour will help maintain its light and airy texture. Experiment with different types of flour to find the perfect balance for your favorite quick bread recipes.

Tips for Mixing Your Quick Bread Batter to Avoid Sinking

When mixing the batter, start by whisking the dry ingredients together in a separate bowl. Then beat the wet ingredients together in a different bowl. Once both mixtures are thoroughly mixed, gradually add the dry ingredients to the wet ingredients, stirring until combined.

It’s important to not overmix the batter, as this can cause the bread to become tough and dense. Mix until just combined, and if there are a few lumps remaining, that’s okay. Another tip is to avoid using a mixer or food processor, as these can overmix the batter quickly. Instead, use a whisk or spatula to gently fold the ingredients together.

The Importance of Proper Oven Temperature for Perfect Quick Bread

Preheat the oven to the correct temperature before adding the quick bread batter. If the oven temperature is too low, the bread will not rise properly and may sink in the middle. If the oven temperature is too high, the bread will overcook, resulting in a dry and crumbly texture.

It is important to note that different types of quick bread may require different oven temperatures. For example, banana bread may require a slightly lower temperature than zucchini bread. Always refer to the recipe for specific oven temperature instructions. Additionally, it is recommended to use an oven thermometer to ensure the oven is at the correct temperature, as oven dials can be inaccurate.

How to Test if Your Quick Bread is Fully Baked or Undercooked

To test if your quick bread is fully baked, insert a toothpick or cake tester into the center of the bread. If it comes out clean, then the bread is fully baked. If there is any batter or crumbs stuck on the toothpick, the bread needs to bake for a few more minutes.

It is important to note that different types of quick bread may require different baking times. For example, banana bread may take longer to bake than zucchini bread due to the moisture content in the bananas. It is always a good idea to check the bread at the minimum recommended baking time and then continue to check it every few minutes until it is fully baked.

If you find that your quick bread is browning too quickly on the top, you can cover it with aluminum foil to prevent further browning while the center continues to bake. This is especially helpful if you are using a dark-colored baking pan, which tends to absorb more heat and can cause the bread to brown faster.

Choosing the Right Pan Size and Shape for Perfect Quick Bread

Use the pan size and shape specified in the recipe. A too-small pan will cause the batter to overflow while a too-large pan will result in a flat and dried out bread. For a taller loaf, use a loaf pan, and for a flatter and crispier crust, use a wider, shallower pan or a muffin pan.

It’s also important to consider the material of the pan. Glass and ceramic pans tend to heat up slower than metal pans, which can affect the baking time and texture of the bread. Additionally, non-stick pans can make it easier to remove the bread from the pan, but they may not produce as crispy of a crust as a regular metal pan. Keep these factors in mind when selecting the perfect pan for your quick bread recipe.

How to Store Your Quick Bread to Maintain its Freshness and Moisture

Once the quick bread is completely cooled, store it in an airtight container at room temperature for up to three days. For longer storage, wrap the bread tightly in plastic wrap and then place it in a ziplock bag in the freezer for up to three months. To thaw, let the bread sit out for a few hours at room temperature or warm it up in the oven or microwave.

By understanding the science of quick bread baking, measuring ingredients accurately, and following our helpful tips, you can achieve perfectly baked quick bread with no sinking in the middle.
