Add a little twist to the traditional apple crumble with this British specialty. A great fall dessert, this easy recipe is a more luxurious version, with a muesli made of oats, dried fruits, and nuts in the crumble mix, resulting in a fruity base and crunchy topping that is absolutely decadent. Top this crumble off with custard, whipped cream, or homemade ice cream for the ultimate treat. 

British Bramley apples are used in this recipe as they are considered some of the best apples for cooking; the balance between the sugar and acid found in the Bramleys helps to keep their tangy flavor when cooked. However, there are many types of apples that can be used to make an apple crumble; just be sure to avoid the really hard varieties such as the Granny Smith.


For the Filling:

  • 1 pound (450 g) apples, preferably Bramley or other cooking apples

  • 2 tablespoons golden caster sugar

For the Topping:

  • 6 ounces (175 g) all-purpose flour

  • 4 ounces (115 g) demerara sugar

  • 4 ounces (115 g) butter, cold, diced

  • 1/2 cup (43 g) oat-based muesli or 1/4 cup (23 g) rolled oats plus 1/4 cup (23 g) mixed dried fruits and nuts

Steps to Make It

  1. Gather the ingredients. Preheat the oven to 375 F/180 C/Gas Mark 5.

  2. Prepare the filling by peeling, coring, and chopping the apples into bite-sized chunks. Don't cut the apples too small or they will disintegrate.

  3. Grease a shallow 9 x 7-inch/23 x 18-centimeter baking dish. Put the apples in the dish, sprinkle the caster sugar over, and set aside.

  4. To make the topping, put the flour, demerara sugar, and butter in a large bowl.

  5. Rub the butter into the flour and sugar until you have a very coarse sand-like mixture. Don't worry too much about making it look uniform; this is a rustic dish and works well with an uneven texture.

  6. Stir the muesli (or the oats plus fruits and nuts) into the crumble mixture.

  7. Sprinkle the crumble topping over the apples. The layer should be about half as thick as that of the apples; if it's too thick, it will not cook through.

  8. Bake the crumble until golden and the liquid is bubbling, about 30 minutes.

  9. Remove the crumble from the oven and let sit for 5 minutes. Serve with custard or a large dollop of good vanilla ice cream.

What Is Caster Sugar?

Caster sugar is the name for fine sugar in the U.K. and comes in two varieties, white and golden. Golden caster sugar is unrefined and has a golden color. If you can't find it, use ordinary white caster sugar instead.

Crumble vs. Crisp vs. Cobbler

These three types of desserts are similar in the sense that they have a fruit base with some sort of pasty-like topping. A cobbler is crowned with a biscuit mixture, while crumbles and crisps have a streusel on top. The lines blur a bit when it comes to crumbles and crisps; technically, a crumble doesn't include oats, but over time both types of desserts have tended to feature this crunchy ingredient.
