Most cakes are baked without water. If the electric oven you use is too small, it's really easy to burn. Generally, it is best to use a household electric oven with a capacity of more than 20 liters. In addition, the temperature should be controlled during baking. Even if you bake the same cake, the effect of baking in different ovens is different, so you need to get familiar with your own oven gradually. If the bottom is easy to burn, you can turn down the temperature, or turn off the heating pipe at the bottom before baking.
