Apple & Blackberry Crumble Cake

The scent of warm apples and berries baking always transports me back to my grandmother’s kitchen. I can almost feel the sun streaming through the window as she pulled a bubbling crumble from the oven, its golden-brown topping practically begging to be broken into. The tartness of the blackberries perfectly balanced the sweetness of the apples, all nestled within a buttery, crumbly hug. It wasn’t just a dessert; it was a memory in every bite, a taste of home that I cherish to this day. Now, I share my version of the perfect Apple & Blackberry Crumble Cake.

Recipe Overview

• Cook Time: 50 minutes
• Total Time: 1 hour 10 minutes
• Servings: 8
• Yield: 1 cake
• Dietary Type: Not specified

Ingredients

• For the Crumble Topping:

  • 50g butter
  • 50g flour
  • 50g light brown sugar

• For the Cake:

  • 225g butter, softened
  • 225g caster sugar
  • 4 medium free-range eggs, beaten
  • 175g self-raising flour
  • 1 teaspoon baking powder
  • 50g ground almonds

• For the Fruit Filling:

  • 2 small cooking apples, peeled, cored, and cut into chunky slices
  • 250g blackberries (or other berries, fresh or frozen)

Equipment Needed

• 23cm spring-clip cake tin
• Mixing bowl
• Electric mixer or hand-held mixer
• Rubber spatula or wooden spoon
• Wire rack
• Oven

Instructions

1. Preheat your oven to 180ºC (350°F). Grease and line the base of a 23cm spring-clip cake tin with parchment paper to prevent sticking.

2. Prepare the crumble topping: In a mixing bowl, rub together 50g butter and 50g flour with your fingertips until the mixture resembles breadcrumbs. The smaller the pieces of butter, the finer the crumble will be.

3. Mix in 50g light brown sugar into the crumble mixture. This will add sweetness and a lovely caramel flavour to the topping. Set the crumble topping aside in the fridge to keep the butter cold and prevent it from melting before baking.

4. Make the cake batter: In a separate mixing bowl, cream together 225g softened butter and 225g caster sugar using an electric mixer or a hand-held mixer until the mixture is pale and fluffy. This step is crucial for incorporating air into the batter, which will result in a lighter, more tender cake.

5. Gradually add the 4 beaten eggs to the creamed butter and sugar mixture, mixing well after each addition. Adding the eggs slowly prevents the batter from curdling. If the batter does curdle slightly, add a tablespoon of flour to help bring it back together.

6. Gently fold in 175g self-raising flour, 50g ground almonds, and 1 teaspoon baking powder. Be careful not to overmix the batter, as this can develop the gluten in the flour and result in a tough cake. Fold until just combined.

7. Transfer the cake batter to the prepared cake tin, spreading it evenly across the base.

8. Arrange the apple slices on top of the cake batter. Distribute them evenly, ensuring that they are slightly submerged in the batter.

9. Scatter the blackberries (or other berries) over the apple slices. If using frozen berries, defrost them thoroughly and drain off any excess liquid before adding them to the cake. This prevents the cake from becoming soggy.

10. Sprinkle the chilled crumble topping evenly over the fruit. Ensure that the entire surface is covered with the crumble.

11. Bake in the preheated oven for 50 minutes, or until a skewer inserted into the middle of the cake comes out clean. If the crumble topping starts to brown too quickly, tent the cake with foil to prevent it from burning.

12. Once baked, leave the cake in the tin on a wire rack for 5 minutes before carefully turning it out. This allows the cake to cool slightly and prevents it from breaking apart when you remove it from the tin.

13. Serve the Apple & Blackberry Crumble Cake warm with custard, whipped cream, or a scoop of vanilla ice cream.

Expert Tips & Tricks

• For an extra-crisp crumble topping, add a handful of rolled oats to the mixture.
• If you don’t have light brown sugar, you can use granulated sugar instead, but the light brown sugar adds a lovely depth of flavour.
• To prevent the fruit from sinking to the bottom of the cake, toss it lightly in a tablespoon of flour before adding it to the batter.
• If you want a richer flavour, use brown butter in the crumble topping. To make brown butter, melt the butter in a saucepan over medium heat and cook until it turns a nutty brown colour. Be careful not to burn it.
• If the cake starts to brown too quickly, cover it loosely with foil during the last 15-20 minutes of baking.

Serving & Storage Suggestions

This Apple & Blackberry Crumble Cake is best served warm, either on its own or with a dollop of creamy vanilla custard, whipped cream, or a scoop of ice cream. The contrast of the warm cake and the cold topping is simply divine.

To store leftovers, allow the cake to cool completely before wrapping it tightly in plastic wrap or placing it in an airtight container. The cake will keep at room temperature for up to 2 days or in the refrigerator for up to 4 days.

To reheat, warm individual slices in the microwave for 20-30 seconds or bake the entire cake in a preheated oven at 180°C (350°F) for 10-15 minutes.

You can also freeze the cake for up to 3 months. Wrap it tightly in plastic wrap and then in foil before freezing. Thaw overnight in the refrigerator before reheating.
