Why cakes cook faster on top shelf?

* Heat Distribution: Ovens are designed with heating elements at the top and bottom. The top element is often the primary source of heat, and the heat rises towards the top of the oven. This means the top shelf receives the most direct heat.

* Convection: Even in a conventional oven, some hot air naturally circulates. This convection current carries heat upwards, making the top shelf slightly hotter than lower shelves.

* Distance from Heating Element: The top shelf is closer to the heating element, leading to faster heat transfer and more even browning.

Important Note: While the top shelf is generally the hottest, it's crucial to check your oven's instructions and recommendations. Some ovens have different heating patterns, and you might find that a different shelf is the most efficient for your specific model.

Always use an oven thermometer to ensure accurate temperature and adjust your baking times accordingly.
