In your electric oven you have two heating elements one on the top and one on the bottom which one should you use to bake a normal cake?

Depends on the type of oven.

If it's fan assisted, then it shouldn't matter as the temperature will be same all over the oven.

If not, then it's best to use the lower plate as it will be cooler.

If in doubt. Check the temperature of the different levels of the oven and compare to the recipe.
