Blackberry and Apple Crumble Cake

Sorry to post an autumn recipe while it's still technically summer, but I've seen blackberries coming out already and the apples look set to follow suit. Best to be prepared eh?

Blackberry and Apple Crumble Cake is really delicious served slightly warm with some custard, cream or crème fraîche. It also tastes great cold the following day. It's a great way to use up small quantities of blackberries and apples rather than a glut.

It's a really easy recipe to make with kids too, even better if they helped collect the fruit. It's always best to freeze blackberries before baking with them as they don't get squashed when you mix. I like to make this cake in a large flat tray so everyone gets a decent layer of crumble.

  • Makes: 16 slices
  • Time: 20 mins prep + 60 mins baking
  • Cost: 32p per serving
  • Calories: 351 per serving

For the cake:

  • 225g butter at room temperature
  • 250g golden caster sugar
  • 3 eggs, whisked
  • 250g self-raising white flour
  • 1 teaspoon of baking powder
  • Good teaspoon of cinnamon (optional)
  • 3 windfall apples, peeled and finely sliced
  • 120g blackberries (preferably frozen)
  • Icing sugar to dredge (optional)

For the crumble topping:

  • 45g butter, cubed, at room temperature
  • 35g caster sugar
  • 70g white flour
  1. Pre-heat the oven to 180 C / 160 fan / gas mark 4. Grease medium sized rectangular roasting tin, around 35cm on the longest side or line with baking paper.
  2. Start by making the crumble topping. Mix all the ingredients for the crumble topping in a bowl with your fingertips until it resembles coarse breadcrumbs. Set to one side.
  3. To make the cake, cream the butter and sugar together with an electric hand whisk until smooth. Add the eggs gradually using the electric whisk to incorporate. Don't worry if it's curdles a little. Sieve the flour, baking powder and cinnamon into the bowl and use a spatula or metal spoon to fold it into the mixture until well incorporated. Finally fold in the chopped apples and blackberries.
  4. Pour the mixture into the prepared tin and use the spatula to press blackberry and apple crumble cake mixture into the edges of the tin and spread it flat. Bake for around 60 minutes until a skewer comes out clean and the cake has a slight springy texture. Check it halfway through baking and if the cake is browning before it's cooked through then loosely cover the top of the cake with a layer of foil.
  5. Leave for around 10 minutes to cool and dredge with icing sugar before serving if you like.
