Equipment

  • 1 23cm squared baking tray or one equal to
  • 1 wire rack
  • 1 electric handmixer

Ingredients
  

FOR THE STEWED RHUBARB

  • 300 g rhubarb
  • 45 g caster sugar
  • 2-3 tbsp water from the rhubarb after being defrosted or use 2 tbsp water if using fresh rhubarb

FOR THE BLONDIE

  • 200 g salted butter
  • 3 eggs
  • 125 g gluten free plain flour
  • 250 g caster sugar
  • 70 g custard powder sieved
  • 1/4 tsp xantham gum add only if flour doesn't already contain it
  • 100-120 g white chocolate chips or chopped chocolate

Instructions
 

FOR THE STEWED RHUBARB

  • Chop the rhubarb up and place in a saucepan with the sugar and water.
  • Cook over a medium heat for 5 minutes stirring every now and then. You can place a lid on for it to cook quicker.
  • Once mostly stewed down, turn off the heat and leave to cool.

FOR THE BLONDIES

  • Preheat the oven to 180℃/160℃ Fan. Line a baking 23cm baking tray with greaseproof paper. Make sure some overhangs the tray.
  • Melt your butter in a saucepan on a low heat and add to a large bowl with the rest of the caster sugar. Beat until smooth.
  • Add the eggs one at a time and beat well between each addition.
  • Add the gluten free plain flour in 3 lots and thoroughly beat in between each addition.
  • Sieve your custard powder and xantham gum into the batter and beat once more.
  • Fold in the white chocolate chips and pour into the baking tray.
  • Evenly dollop spoonfuls of stewed rhubarb on top until it's all used up and place in the oven to bake for 35-50 minutes. The cooking time may vary depending on your oven.
  • Once fully baked, remove from the oven and leave to fully cool in the tray. It carries on cooking after being baked so you need it to cool completely and set before cutting up I'm afraid!
  • Once cooled completely you can cut the blondie up and enjoy with a good cup of tea!
