1-Getting started: with Berry Crumb Cake is straightforward and fun, especially when you follow these steps. First, preheat your oven to 200°C / 400°F (180°C fan-forced) and line a 20cm springform pan with parchment paper for easy removal later. This setup helps the cake bake evenly and come out looking great.

2-Next, prepare the streusel: by mixing 2/3 cups plain/all-purpose flour, 1/2 cup caster sugar, 1/2 tsp cinnamon powder, and 1/8 tsp salt in a bowl. Add 60g / 4 tbsp melted butter and 1/4 tsp vanilla extract, then stir with a fork until it’s lumpy and crumbly that’s your crunchy topping ready to go. While that’s set, zest your lemon to get 1 tbsp lemon zest and set it aside for the cake batter.

3-For the blueberries: toss 500g / 1 lb fresh or frozen blueberries with 2 tsp lemon juice, then sprinkle 2 tbsp caster sugar and 3 tbsp plain/all-purpose flour over them and mix to coat evenly. In a small bowl, whisk together 1 1/3 cups plain/all-purpose flour, 2 tsp baking powder, and 1/4 tsp salt. In a larger bowl, whisk 3/4 cup caster sugar, 1 tsp vanilla extract, 1 tbsp lemon zest, and 2 large eggs at room temperature until foamy (about 15 seconds). Add 90g / 6 tbsp unsalted butter (melted and cooled slightly) and 1/3 cup sour cream at room temperature, whisking until smooth.

4-Now, fold the dry ingredients: into the wet mixture in three additions using a rubber spatula, then stir in 1/3 cup milk at room temperature until combined don’t worry about small lumps. Pour the batter into your prepared pan and smooth it out. Scatter the blueberries evenly on top, including any extra flour and sugar from the bowl, then cover with the streusel, pressing powdery bits into clumps for about 85% coverage.

5-Bake: for 65 minutes, rotating the pan halfway, until a skewer inserted in the center comes out clean (a little blueberry on it is okay). Let the cake cool in the pan for 10 minutes, then remove the springform ring and cool for another 10 minutes before serving. It’s best warm, maybe with a scoop of vanilla ice cream for that extra treat. Explore outdoor cooking tips from our blog to pair this cake with your grilling adventures.
