Beat the eggs in a bowl, the mix in the oil. Add the vanilla extract, baking soda, salt, and cinnamon and mix. Add the flour and sugar and stir. The batter will be thick. Add the apples and stir well.
Spoon into the loaf pan. If you're using the topping, sprinkle on top of the batter before baking.
Bake at 350 for 1 hour. It's best to let the bread cool before slicing although you may find it hard to resist as it smells so good!
