Apple and blackberry crumble

Preheat the oven to 160°C/gas mark 3

To make the crumble topping, combine all of the ingredients in a food processor and blend until they resemble breadcrumbs

Spread out the crumble on a baking tray and bake in the oven for 30-40 minutes, being sure to stir the crumble mixture every 10 minutes. Remove when the mixture is golden-brown and set aside to cool

To make the apple and blackberry filling, peel and core the apples then cut them into even-sized pieces, about 3-4cm wide

Put a heavy-based saucepan over a medium heat and add the butter. When it starts to foam, add the apple pieces

Cook gently for 5–8 minutes until the apple is just becoming tender, then add the blackberries and sugar and continue cooking for a further 8–10 minutes

Spoon the filling into an ovenproof dish and sprinkle liberally with the crumble topping. Bake for 10–12 minutes before serving with hot custard, cream, vanilla ice cream, or all three!
