Step 1: Prepare the Streusel Topping

1. In a medium bowl, combine the following ingredients:
   • 2/3 cup (100g) all-purpose flour
   • 1/2 cup (100g) caster sugar (superfine sugar)
   • 1/2 teaspoon cinnamon
   • 1/8 teaspoon salt
2. Add:
   • 4 tablespoons (60g) melted butter
   • 1/4 teaspoon vanilla extract
3. Mix with a fork until the mixture is lumpy. Set aside.

Step 2: Prepare the Blueberries

1. In a large bowl, toss:
   • 500g (1 lb) fresh blueberries
   • 2 teaspoons lemon juice
2. Sprinkle over:
   • 2 tablespoons white sugar
   • 3 tablespoons flour
3. Mix gently to coat the blueberries evenly. If using frozen blueberries, keep them frozen until after you prepare the batter to prevent bleeding.

Step 3: Make the Lemon Vanilla Cake Batter

1. In a separate bowl, whisk together:
   • 1 1/3 cups (200g) all-purpose flour
   • 2 teaspoons baking powder
   • 1/4 teaspoon salt
2. In a larger bowl, whisk together:
   • 3/4 cup (150g) caster sugar
   • 1 teaspoon vanilla extract
   • 1 tablespoon lemon zest
   • 2 large eggs (at room temperature)
3. Slowly whisk in:
   • 6 tablespoons (90g) melted and cooled unsalted butter
   • 1/3 cup (70g) sour cream (or yogurt, also at room temperature)
4. Gradually fold in the flour mixture in three batches using a rubber spatula until just combined.
5. Mix in:
   • 1/3 cup (80ml) milk (at room temperature)

Step 4: Assemble the Cake

1. Preheat your oven to 200°C (400°F) or 180°C (356°F) for fan-assisted ovens.
2. Line a 20cm (8-inch) round cake pan with parchment paper.
3. Pour the batter into the prepared pan and spread it evenly.
4. Top with the blueberries, ensuring to include any residual flour from the coating.
5. Crumble the prepared streusel topping evenly over the blueberries.

Step 5: Bake the Cake

1. Bake in the preheated oven for approximately 65 minutes, or until a toothpick inserted into the center comes out clean.
2. Once baked, cool the cake in the pan for 10 minutes before transferring it to a wire rack to cool for another 10 minutes.

Step 6: Serve

• Enjoy the cake warm, ideally with a scoop of vanilla ice cream, or serve at room temperature. The cake is delicious either way!
