For a richer flavor, use brown sugar instead of granulated sugar in the crumble topping. If you don't have custard powder, you can substitute it with cornstarch for a slightly different texture. Feel free to add other spices to the apple filling, such as nutmeg or allspice. For a gluten-free version, use a gluten-free all-purpose flour blend for the crust and crumble topping. The crumble can be made ahead of time and stored in the refrigerator for up to 24 hours before baking.
