Mary Berry Apple and Blackberry Crumble Cake Ingredients
For the Cake:
- 150g (5½oz) butter, softened
- 125g (4½oz) caster sugar
- 3 large eggs
- 50g (2oz) ground almonds
- 100g (3½oz) self-raising flour
- 1 large pinch of cinnamon
- 2 eating apples (like Discovery or Russet), peeled, cored, and cut into segments
- 100g (3½oz) blackberries
For the Crumble Topping:
- 100g (3½oz) plain flour
- 50g (2oz) unsalted butter, cold and cubed
- 50g (2oz) caster sugar
- 25g (1oz) hazelnuts, chopped (optional)
How To Make Mary Berry’s Apple and Blackberry Crumble Cake
- Prep the oven and make the crumble: Preheat the oven to 180°C/160°C Fan/Gas 4. Grease a 20cm (8in) round, loose-bottomed cake tin and line the base with non-stick baking paper. For the crumble, rub the cold butter into the plain flour with your fingertips until it resembles breadcrumbs, then stir in the sugar and optional hazelnuts.
- Make the cake batter: In a large bowl, cream the softened butter and caster sugar together until light and fluffy. Beat in the eggs one at a time.
- Combine and assemble: Gently fold in the ground almonds, self-raising flour, and cinnamon until just combined. Fold in the apple segments and half of the blackberries.
- Layer and bake: Spoon the batter into the prepared cake tin and level the top. Scatter the remaining blackberries over the surface, then sprinkle the crumble topping evenly over everything.
- Bake and cool: Bake for 50-60 minutes, or until the cake is golden, well-risen, and a skewer inserted into the center comes out clean. Let the cake cool in the tin for 10 minutes before releasing it to cool completely on a wire rack.

Recipe Tips
- How to get the best texture? Using ground almonds in the cake batter is a classic Mary Berry trick that adds wonderful moisture and a delicate texture to the sponge.
- Can I use different apples? Yes. Any good eating apple that holds its shape when cooked, such as a Cox or Braeburn, will work well. Avoid apples that turn to mush, like Bramleys, for this particular cake.
- Can I use frozen blackberries? You can, but it’s best to add them to the batter while still frozen to prevent them from bleeding their color too much into the cake.
- How to prevent the top from browning too quickly? If you notice the crumble topping is getting too dark before the cake is cooked through, you can loosely cover the tin with a piece of aluminum foil for the remainder of the baking time.

FAQs
Yes, you can simply omit the ground almonds from the cake and the optional hazelnuts from the crumble topping for a nut-free version.
This can happen if your batter is too thin or if the fruit pieces are too heavy. Tossing the fruit in a tablespoon of flour before folding it into the batter can help to suspend it more evenly.
Yes, you could make this in a 20cm (8in) square tin. The baking time should be similar, but always check for doneness with a skewer.
