Cakes sinking in the middle is a common baking issue, and it usually happens because of problems related to mixing, baking time, or ingredient balance. Here are the main reasons why cakes sink in the middle:
1. Underbaking
If the cake is not baked long enough, the center remains raw and can collapse as it cools.
Fix: Always check doneness with a toothpick—if it comes out clean or with a few crumbs, it's ready.
2. Overmixing the Batter
Mixing too much adds excess air and develops too much gluten, causing the cake to rise fast and then sink.
Fix: Mix just until the ingredients are combined and smooth.
3. Too Much Leavening (Baking Powder or Baking Soda)
Excess causes the cake to rise too quickly, then collapse as the structure can't support it.
Fix: Measure leavening agents accurately.
4. Incorrect Oven Temperature
Too low: cake rises slowly and sinks.
Too high: cake rises quickly and collapses before setting.
Fix: Use an oven thermometer to ensure accurate temperature.
5. Opening the Oven Door Too Early
Sudden drop in temperature causes the cake to sink.
Fix: Avoid opening the oven in the first 20–25 minutes of baking.
6. Too Much Liquid or Sugar
Imbalance in the ratio of wet to dry ingredients can weaken the cake’s structure.
Fix: Follow tested recipes and measure ingredients properly.
7. Expired Leavening Agents
Old baking powder or baking soda won’t work well, resulting in a flat or sunken cake.
Fix: Check expiration dates and test them before use.
8. Using the Wrong Pan Size
A pan that's too small can cause the center to remain undercooked.
Fix: Use the pan size recommended in the recipe.
