Nobody can resist these wonderfully chocolatey brownies, and, unusually, they are made with mayonnaise, rather than butter or spread! Look for chocolate with around 70% cocoa solids for the best flavour.

  • ½ teaspoon low fat spread
  • 75g (2 ¾ oz) dark chocolate, about 70% cocoa solids, broken into even-sized pieces
  • 75g(2 ¾ oz) plain flour
  • ¼ teaspoon bicarbonate of soda
  • 150g (5 ½ oz) caster sugar
  • 25g (1 oz) cocoa powder
  • 2 eggs, separated
  • 100g (3 ½ oz) extra light mayonnaise
  • 1 teaspoon vanilla extract
  • 2 tablespoons skimmed milk


  1. Preheat the oven to Gas mark 4/180°C/fan oven 160°C. Line the base of an 18 cm (7inch) square cake tin with baking paper and grease the sides with the low fat spread.
  2. Fill a medium size saucepan with about 4cm (1 ½ inches) of hot water. Put the chocolate in a heatproof bowl and rest the bowl on top of the pan so it fits snugly-do not let the water touch the bottom of the bowl. Bring the water to a gentle simmer and heat the chocolate, stirring occasionally until it has melted. Carefully remove the bowl from the pan and let the melted chocolate cool slightly.
  3. Sift the flour and bicarbonate of soda into a large mixing bowl. Reserving 1 teaspoon of the cocoa powder, stir the rest into the mixture, then stir in the sugar.
  4. Beat together the egg yolks, mayonnaise, vanilla extract and milk in a separate bowl, then stir this mixture into the flour mixture. Stir in the melted chocolate.
  5. Whisk the egg whites in a clean, grease-free bowl for about 1 minute, until they form soft peaks, then carefully fold them into the chocolate mixture with a metal spoon.
  6. Pour the mixture into the tin, spread into an even layer and bake for 20-25 minutes until the cake is risen and just firm. Leave to cool in the tin, then turn out and cut into 16 pieces.
