Ingredients
30 g | Unsalted butter, chilled and cut into small cubes |
2 cups | Plain flour |
125 g | Unsalted butter, softened |
2 tsp | Baking powder |
1 ½ Tbsp | Brown sugar |
1 cup | Caster sugar |
3 | Eggs |
250 g | Sour cream, (1 cup) |
350 g | Plums, halved and stoned (Main) |
250 g | Blackberries (Main) |
1 to serve | Cream |
Directions
- Preheat the oven to 170 degC.
- Lightly grease a 22cm-square cake tin and line with baking paper, letting the paper overhang slightly around the rim to assist with removing the streusel once cooked.
- To make the topping, place 50g of the flour in a bowl, add the cold cubed butter and rub in until the mixture resembles coarse breadcrumbs. Mix in the brown sugar and set aside.
- To make the cake, sift the remaining flour, the baking powder and a pinch of sea salt into a bowl. In a large bowl, cream the softened butter and caster sugar with electric beaters.
- Add the eggs, one at a time, beating well after each addition.
- Tip in the dry ingredients, alternating with the sour cream, while being careful not to over-mix (some small lumps of flour are okay).
- Pour the batter into the lined cake tin and scatter over the plums and 150g of the blackberries, then finish with the topping.
- Bake for 55-60 minutes, or until a skewer inserted into the centre comes out clean.
- Allow the streusel to cool a little before lifting it out of the tin.
- Serve warm or at room temperature with the remaining blackberries and cream.
