How to Make Mary Berry Apple and Blackberry Crumble Cake
- Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease and line a 23cm round springform cake tin with baking parchment.
- Make the crumble topping: Place the plain flour and cold butter into a bowl. Rub together with your fingertips until the mixture resembles fine breadcrumbs. Stir in the light brown sugar and set aside.
- Prepare the fruit: Combine the diced apples, blackberries, caster sugar and cinnamon in a bowl. Toss gently until evenly coated.
- Mix the cake batter: Place the butter, caster sugar, eggs, self-raising flour, baking powder, milk and vanilla extract into a large mixing bowl. Beat until smooth, pale and fully combined.
- Fill the tin: Spoon the cake batter into the prepared tin and level the surface with a spatula.
- Add the fruit: Scatter the apple and blackberry mixture evenly over the cake batter.
- Add the crumble topping: Sprinkle the crumble mixture evenly over the fruit layer, covering the surface completely.
- Bake the cake: Place the tin in the centre of the oven and bake for 50 to 60 minutes, or until the crumble is golden and a skewer inserted into the cake comes out clean.
- Cool the cake: Leave the cake in the tin for 15 minutes before removing. Transfer to a wire rack and allow to cool completely.
- Finish and serve: Dust lightly with icing sugar before slicing and serving.

Tips for the Best Apple and Blackberry Crumble Cake
How do I stop the fruit from sinking?
Cut the apples into small, even pieces and avoid using overly wet fruit. The thick batter helps support the fruit during baking.
Why is my crumble topping not crunchy?
Always use cold butter when making the crumble. Warm butter can create a dense topping instead of a crisp, crumbly finish.
Can I use frozen blackberries?
Yes. Use them directly from frozen without thawing to prevent excess moisture from affecting the cake.
How do I know when the cake is fully baked?
Insert a skewer into the centre. If it comes out clean and the crumble topping is golden brown, the cake is ready.
Can I add extra flavour?
A little lemon zest or mixed spice works beautifully with the apples and blackberries and adds extra depth of flavour.
