300g/10 ½ oz/2 cups raspberries

175g/6oz/scant 1 cup light soft brown sugar

1 tsp vanilla extract

INSTRUCTIONS

1. Preheat the oven to 180º C/350ºF/Gas 4 and grease and line a 23cm/9in round springform cake tin.

2. Arrange the raspberries, hole-side down, across the base of the prepared tin, wedging them in so they are tightly packed. Reserve any left over.

3. Beat together the butter and sugar in a large bowl, using an electric mixer, until pale and fluffy.

4. Stir in the vanilla and the eggs, one at a time, adding a spoonful of the flour with each egg to prevent the mixture from splitting.

5. Add the ground almonds and stir, then add the remaining flour, baking powder and salt and stir through until the mixture is evenly blended and there are no major lumps of flour.

6. Carefully fold in any remaining raspberries, stirring once or twice.

7. Spoon the cake mixture into the prepared tin and smooth the top.

8. Bake for 45-60 minutes, or until a skewer inserted in the centre comes out clean.

9. Turn upside down on to a wire rack to cool.

10. Sprinkle with caster or icing sugar, if you like, and serve with double cream or crème fraiche.
