  • 225 g (generous 1 cup) caster sugar
  • 4 large eggs
  • 240 ml (1 cup) light vegetable or olive oil
  • 1 tsp vanilla extract or paste
  • finely grated zest of 1 orange or lemon
  • 250 g (2 cups) self-raising flour
  • 1 tsp baking powder
  • 3 Tbsp poppy seeds
  • 8-10 ripe plums halved and stones removed
  • 2 Tbsp icing (powdered) sugar
  • 1 tsp ground cinnamon


  • Preheat the oven to 180C/350F/gas mark 4. Grease and line a 30x23cm/12x9in cake tin.
  • Place the sugar, eggs, oil and vanilla in a large bowl and whisk with an electric mixer for 5 minutes until pale and fluffy. Add the zest and mix again.
  • Sift together the flour and baking powder and gently fold it in using a metal spoon until it is fully combined. Add the poppy seeds and mix again.
  • Pour the batter into the lined tray and spread it level. Arrange the plum halves on top, cut side down. Bake for about 40-50 minutes, until the cake is firm and a skewer inserted into the centre comes out clean.
  • Leave to cool in the tin. Before serving, mix together the icing sugar and cinnamon and sift it over the cake.
