FAQs

Why is my apple crumble with oats not crunchy?

This usually happens if the butter is too soft or the crumble topping is overmixed. Rubbing the butter in lightly and keeping the mixture crumbly helps create a crisp, golden topping.

Should apples be cooked before adding the crumble topping?

Lightly cooking the apples first helps soften them and releases excess moisture. This step prevents a watery base and ensures the apples are tender when the crumble is baked.

Which apples work best for apple crumble with oats?

Cooking apples such as Bramley are ideal because they break down slightly and give a balanced sweet-tart flavour. You can mix them with eating apples for extra texture.

How do I stop the crumble topping from browning too quickly?

If the topping colours too fast, loosely cover the dish with foil for the final part of baking. This allows the apples to finish cooking without burning the oats.
