  • 200 g Butter or baking spread
  • 300 g Golden caster sugar or regular caster sugar
  • 150 g White chocolate broken into pieces (see notes)
  • 3 Eggs large
  • 1 tsp Vanilla extract
  • 225 g Plain flour
  • 12 Jammie Dodger biscuits
  • 6 tbsp Strawberry Jam or other flavour of your choice


  • Pre heat your oven to 160C Fan/180C/350F/Gas Mark 4, and grease and line a 12" x 9" traybake tin
  • Melt the butter with the golden caster sugar in a pan on a low heat
  • Once the butter has melted, take the pan off the heat and add the white chocolate. Leave it for a couple of minutes to melt, then stir together. Leave the mixture to cool for 5 minutes
  • Break the eggs into a bowl and add them to the mixture, keep whisking as you pour them in to make sure the mixture doesn't cook the eggs. Then stir in the vanilla extract
  • Add the flour and whisk it in, then pour the batter into the lined traybake tin
  • Place the Jammie Dodger biscuits in rows on top of the batter, then add blobs of strawberry jam all around the biscuits, once you are happy with the amount of jam, swirl it around gently using a butter knife
  • Bake the blondies for 30 minutes, or until they are golden brown all over. Using a skewer inserted in the centre doesn’t give a clear indication that they are done because blondies are meant to be gooey and almost a little under cooked. Blondies are the white chocolate version of brownies and they are not like cake. They will also set more as they cool down, wait until they are cool to remove them from the tin and slice into pieces
  • Store in an airtight container in a cool place and eat within 3 days



If you would like to use a 8" or 9" square tin instead, reduce the recipe by one third. So you will need:
  • 135g Butter
  • 200g Golden caster sugar
  • 100g White chocolate
  • 2 Eggs
  • ¾ tsp Vanilla
  • 150g Plain flour
  • 4 tbsp Strawberry jam
  • 9 Jammie Dodger biscuits
They will also need less time to bake, depending on your oven, I'd suggest 20-25 minutes.
Use a good quality white chocolate, it doesn't have to be the top quality kind, but don't use a super cheap one. I've used Tesco white chocolate (the brand is called Molly's) and Callebaut callets many times. Do NOT use cooking or baking chocolate, Milky Bar or any white chocolate with low milk solids. It will affect the final result.
Also use a good quality jam. Cheap jams contain too much sugar and again will affect the final result. Some of my fave brands are Bonn Maman, Mackays and Tesco's Finest.
