Makes 16 Jammy Dodger Blondies 


  • 225g butter 
  • 225g light brown soft sugar 
  • 150g caster sugar 
  • 100g white chocolate, broken into cubes 
  • 3 medium free range eggs 
  • 300g plain flour 
  • 3/4 tsp baking powder 
  • Jammy Dodgers and Mini Jammy Dodgers, to decorate 



Preheat the oven to 200°C/180°C fan/gas 6. Grease and line a 23 x 23cm square tin with baking parchment.
In a large saucepan, heat the butter, light brown sugar and caster sugar together until the mixture has completely melted.
Remove from the heat and allow to cool for 5 minutes, then add the chunks of white chocolate. Stir until melted, then allow the mixture to cool to room temperature.
When the mixture is cool enough to touch comfortably, beat in the eggs. Add the flour and baking powder and stir to combine.


Scrape the mixture into the prepared tin using a spatula to spread it right to the edges, then arrange the biscuits over the top.
Bake in the centre of the oven for 25–30 minutes or until the top is shiny and slightly cracked. Allow to cool completely, then cut into squares.
