Mary Berry Blackberry and Apple Crumble is a traditional British baked dessert made by layering fruit with sugar and topping it with a crumbly mixture of flour, butter, and sugar. As it bakes, the fruit softens and releases its juices while the topping turns crisp and golden, creating a contrast of textures that’s both simple and deeply satisfying.
Cooking apples (such as Bramley): 700 g, peeled, cored, and sliced
Blackberries: 200 g
Caster sugar: 75 g (adjust to taste)
Lemon juice: 1 tablespoon
Plain flour: 175 g
Cold unsalted butter: 100 g, diced
Demerara sugar: 75 g
Prepare the fruit – Place the sliced apples into a bowl, add the blackberries, caster sugar, and lemon juice, then mix gently until evenly coated.
Assemble the base – Spoon the fruit mixture into an ovenproof dish and spread it out evenly.
Make the crumble topping – Add the flour and butter to a bowl and rub together with your fingertips until the mixture resembles coarse breadcrumbs.
Add the sugar – Stir in the demerara sugar, keeping the mixture loose and crumbly.
Top the fruit – Sprinkle the crumble evenly over the fruit without pressing it down.
Bake until golden – Bake in a preheated oven at 190°C (170°C fan) for 35–40 minutes, until the top is crisp and golden and the fruit is bubbling at the edges.
Rest briefly – Let the crumble stand for a few minutes before serving so the juices settle.
