How to Keep Cupcakes from Collapsing
Unfortunately, keeping cupcakes from collapsing is not straightforward. Based on my research into the subject (and personal experience), there are several possible reasons cupcakes collapse:
- Your liners could be overfilled. If your cupcakes collapse instead of doming, the recipe may be at fault. With some recipes, the cupcakes rise and then collapse in the center because the cake can’t hold up its own weight. To correct for this, you simply need to fill the liners less. If you are not sure how high to fill the liners, see my post on how high to fill cupcake liners.
- Your oven temperature could be off. Buy an oven thermometer and check to make sure that you are baking at the correct temperature.
- You don’t have patience. I know it’s hard to not peek at your beauties while they are baking, but try to avoid opening the oven. Every time you do, it affects the oven temperature – which affects the end result of your baked goods.
- You over-mixed. Unless the recipe states otherwise, mix only until the ingredients are just combined. In addition to causing the cupcakes to sink, over-mixing can also make them taste gummy.
- You are baking at great heights. If you live in a high-altitude location, you may need to adjust your recipe to accommodate. You can refer to the King Arthur Flour guide to high-altitude baking for more information.
- You are scared of burning the cupcakes. It’s important to not over-bake your cupcakes, but don’t under-bake them either. Make sure that your cupcakes are actually done before removing them from the oven. Cupcakes removed too soon may sink.
If your cupcakes have sunk, don’t worry. No one will ever know! Just cover the hole with frosting and enjoy!
