I've made loads and it is trivial. You literally just follow the recipe.

Bread is a lot more difficult due to kneeding and shaping which are skills that must be honed.

Cakes, on the other hand, are just mixing and pouring which any idiot can do. The only real variable is the flour so some recipes might work better in your region than others, but cakes are still much more forgiving than bread (flour is more than half of bread by weight, but often less than a third of a cake).
