Why Does My Cake Sink in the Middle?

Why Does My Cake Sink in the Middle?

Baking a cake should be simple, but sometimes things go wrong. One of the most frustrating issues is when a cake sinks in the middle. You take it out of the oven, and instead of a perfect rise, you’re left with a sunken centre. There are many reasons, and most are simple baking mistakes.

Opening the Oven Door Too Soon

Heat is crucial for cakes to rise. If you open the oven door before the cake has set, the rush of cold air can cause the structure to collapse. A cake needs consistent heat, especially in the first half of baking. If you must check, do it towards the end of the baking time and only for a few seconds.

Underbaking the Cake

A cake that isn’t fully baked doesn’t have the strength to hold itself up. The structure inside is still too soft, and when you remove it from the oven, it falls. Always test with a skewer in the centre—if it comes out clean, the cake is ready. If it has wet batter, leave the cake in for longer.

Incorrect Oven Temperature

If the oven is too hot, the cake may rise too fast and collapse. If it’s too cold, it won’t bake evenly, leading to a sunken centre. Always preheat your oven and use an oven thermometer to check the temperature. Some ovens run hotter or colder than the settings suggested.

Too Much Raising Agent

Baking powder and bicarbonate of soda help a cake rise, but too much can cause the cake to puff up quickly and collapse. Stick to the recipe’s measurements. If you’re experimenting with a recipe, add small amounts at a time to avoid overloading the batter.

Overmixing the Batter

Overmixing incorporates too much air, which causes the cake to rise fast in the oven and then deflate as it cools. Mix just until the ingredients are combined. A smooth, even batter is ideal, but don’t keep mixing once everything is incorporated.

Using the Wrong Tin Size

If the tin is too small, the cake will be too deep and may not bake evenly. If it’s too big, the batter will spread too thin and cook too fast, leading to an uneven structure. Follow the recipe’s tin size recommendations or adjust the cooking time if using a different size.

Expired or Old Ingredients

Baking powder and bicarbonate of soda lose their effectiveness over time. If they’re too old, they won’t give the batter the rise it needs, leading to a flat or sunken cake. Always check expiry dates and store ingredients properly.

Too Much Liquid in the Batter

A cake batter that’s too wet won’t hold its structure. If a recipe calls for precise amounts of milk, water, or oil, measure carefully. Even a slight excess can make the cake too heavy, preventing a proper rise.

Not Allowing the Cake to Cool Properly

If you move a cake while it’s still hot, it can collapse. Let it cool in the tin for 10-15 minutes before moving it to a wire rack. Cooling helps it set properly and keeps the structure intact.

Baking Perfect Cakes Every Time

To avoid sinking cakes, follow recipes carefully, measure ingredients accurately, and don’t rush the process. A well-made cake has a light, even texture and holds its shape after baking.
