Blueberry and white chocolate squares

• 250g (8oz) white chocolate
• 75g (3oz) butter, softened
• 125g (4oz) caster sugar
• 2 large eggs, beaten
• 1tsp vanilla extract
• 150g (5oz) self-raising flour
• 150g (5oz) fresh blueberries
  
  
  
  
  1. Preheat the oven to Gas 4, 180ºC, fan160ºC. Grease and line the bottom of a 20cm (8in) square tin with baking paper.
  
  2. Break 175g (6oz) of the chocolate into a bowl and set over a pan of simmering water until melted and smooth. Cool slightly. Roughly chop the remaining chocolate into small pieces and set aside.
  
  3. Using an electric mixer, whisk the butter and sugar together until fluffy. Whisk in the eggs and vanilla extract, then stir in the melted chocolate.
  
  4. Sift the flour and 1/2 tsp salt over the mixture and fold in. Then gently fold in the chocolate pieces and blueberries.
  
  5. Spoon mixture into prepared tin, spread into the corners and level the top with a plastic spatula. Cook for 35-40mins, until a cocktail stick inserted into the centre comes out with a small amount of sticky crumbs. Cool before cutting into 36 squares.
