This makes a lovely dessert with a dollop of yoghurt, or a slice in the lunchbox for a healthy sweet treat!


  • 55 g light margarine
  • ¾ cup caster sugar (or ‘spoon for spoon’ sugar replacer)
  • 1 teaspoon vanilla essence
  • zest of 2 lemon
  • juice of 2 lemons
  • 200 g no-fat diet vanilla yoghurt
  • 5 eggs, separated
  • 1 cup (200 g) instant polenta
  • 2 teaspoons gluten-free baking powder
  • 1 teaspoon bicarbonate of soda
  • 1 teaspoon xanthan gum
  • ½ cup (35 g) desiccated coconut
  • 75 g sultanas
  • extra no-fat diet vanilla yoghurt, to serve


  1. Preheat oven to 170°C/150°C fan-forced. Grease and line a 20 cm spring form cake tin.
  2.  Beat the margarine, sugar (or replacer) and vanilla essence with electric beaters until light and fluffy. Add the zest, juice and yoghurt, then add yolks one at a time, beating well after each addition.
  3. In a large bowl, combine polenta, baking powder, bicarbonate of soda, xanthan gum and coconut, then mix well. Fold this into the egg mixture with a large metal spoon. Add the sultanas, stir through and let sit for 1 hour.
  4. In a separate bowl, beat the egg whites until soft peaks form, then gently fold into the lemon flour mixture. Pour into the cake tin and bake for 45-50 minutes, or until a skewer inserted into the centre comes out clean.
  5. To serve, cut into slices and serve with a dollop of yoghurt.
