Fluted Fresh Fruit Cakes
Suggested variation; try replacing the vanilla with 2 tsp ground cinnamon.
Preheat the oven to 190°C (170 fan) | 375°F | gas 5 and oil a 12-hole silicone cupcake mould.
Combine the flour, sugar, butter, eggs and vanilla extract in a bowl and whisk together for 2 minutes or until smooth. Fold in the plums.
Divide the mixture between the moulds, then transfer the tin to the oven and bake for 15 - 20 minutes. Test with a wooden toothpick, if it comes out clean, the cakes are done. Transfer the cakes to a wire rack and leave to cool before dusting with icing sugar.
