Mayonnaise Brownies

At first sight, you may think mayonnaise brownies sounds disgusting. However, these are truely chocolatey and decadent. Give them a go!

Makes 16


  • 40g (1 1/2 oz) Plain Flour
  • 1 tsp Baking Powder
  • 25g (1oz) Cocoa Powder
  • 140g (4 3/4 oz) Good quality, Plain Chocolate (broken into small pieces).
  • 3 Eggs
  • 225g (71/2 oz) Caster Sugar
  • 1 tsp Vanilla Extract
  • 100g (3 1/2 oz) Mayonnaise

Optional: 55g (2oz) Walnuts, finely chopped.


  1. Grease and line a 23cm (9 inch) square brownie/cake tin. Pre-heat the oven to 180°C (160°C fan).
  2. In a small bowl, mix the flour with the baking powder and cocoa. In a separate bowl, melt the chocolate over a pan of hot water.
  3. In a large bowl, whisk the eggs with the sugar and vanilla until slightly thickened. Whisk in the chocolate, then the mayonnaise. Gently fold in the flour mixture and walnuts (if using). Don’t over mix.
  4. Pour into the prepared tin and bake for 30-35 minutes or until a skewer inserted comes out clean.
  5. Leave to cool in the tin before cutting into squares.
