Everyone loves apple desserts, and this British oaty apple crumble recipe adds a twist to the traditional apple crumble with the additional ingredients in the filling. A great fall dessert, this easy apple crumble is a more luxurious version with oats, dried fruits, and some nuts in the crumble mix. This will result in a fruity base and crunchy topping that is absolutely decadent.

We use British Bramley apples for this recipe. These are considered the best apples for cooking, as the balance between the sugar and acid found in the Bramleys help to keep the tangy flavor when cooked. All styles of apple crumble can be made using other types of apples but avoid the really hard varieties such as the Granny Smith.

Top this crumble off with custard, whipped cream, or homemade ice cream for the ultimate treat. 


  • For the Filling:
  • 1 pound/450 grams apples (preferably Bramley or other cooking apples)
  • 2 tablespoons golden caster sugar
  • For the Topping:
  • 6 ounces/175 grams all-purpose flour
  • 4 ounces/115 grams demerara sugar
  • 4 ounces/115 grams butter (cold, diced)
  • 1/2 cup/43 grams oat-based muesli (or 1/4 cup/23 grams rolled oats plus 1/4 cup/23 grams 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 apples 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 them, and set to one side.

  4. 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 getting the mixture even, this is a rustic dish and works well with an uneven texture.

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

  7. Sprinkle a good, thick layer of crumble topping over the apples. The layer needs to be about half as thick as that of the apples; too thick and it will not cook through.

  8. Put the dish into the preheated oven, bake until golden, and you can see the liquid bubbling up from the apples. This should take about 30 minutes.

  9. Take the crumble from the oven and leave to stand for 5 minutes, then serve with custard or a large dollop of good vanilla ice cream.

Note: Caster sugar is also known as fine sugar. Golden caster sugar is unrefined and tends to be more golden in color. Don't worry if you can't find it—use ordinary white caster sugar instead.
