For baking a cake, it is generally recommended to use both the top and bottom heat elements of your oven, unless a recipe specifically states otherwise. This helps to ensure even baking and browning of the cake.
Using both top and bottom heat elements is referred to as "conventional" or "bake" mode on many ovens. In this mode, heat is generated from both the top and bottom heating elements, creating a consistent temperature throughout the oven cavity.
To set your oven to conventional or bake mode, typically you would select the desired temperature using the oven control panel and then press the start or bake button. The oven will then heat up using both top and bottom heating elements.
Using only the top heat element, referred to as "broil" or "grill" mode, is more suitable for browning the tops of dishes or melting cheese, but it may result in uneven baking for cakes and other delicate baked goods.
Always refer to the specific instructions and temperature recommendations provided in your cake recipe for the best results. If the recipe suggests a different oven setting, follow those guidelines to achieve the intended outcome.
