Ingredients
  

Blondies

  • 200 g unsalted butter melted
  • 125 g granulated sugar
  • 125 g light brown soft sugar
  • 3 medium eggs
  • 1 teaspoon vanilla extract
  • 275 g plain flour
  • 1 tablespoon cornflour
  • 200 g white chocolate chips
  • 200 g pistachios chopped

Decoration

  • 50 g white chocolate melted
  • 25 g pistachios chopped

Instructions
 

Step 1 – Prepare the Tin

  • Preheat oven to 180°C (160°C fan). Line a 9x9-inch square tin with parchment paper and set aside.

Step 2 – Mix the Base

  • In a large mixing bowl, combine the melted butter with granulated sugar and light brown sugar. Mix until smooth.

Step 3 – Add Eggs and Vanilla

  • Add the eggs and vanilla extract. Mix until fully incorporated and glossy.

Step 4 – Add Dry Ingredients

  • Stir in the plain flour and cornflour. Mix gently until just combined. Avoid overmixing to keep the blondies tender.

Step 5 – Fold in Chocolate and Pistachios

  • Fold through the white chocolate chips and chopped pistachios evenly. Pour the batter into the lined tin and smooth the surface.

Step 6 – Bake

  • Bake for 25–30 minutes, until the edges are set but there is still a slight wobble in the center.

Step 7 – Cool and Chill

  • Allow the blondies to cool completely at room temperature, then refrigerate for at least 2–3 hours to fully set for clean slicing.

Step 8 – Decorate

  • Drizzle melted white chocolate over the top and sprinkle with extra chopped pistachios. Let the chocolate set before slicing into 16 squares.
  • White Chocolate & Pistachio Blondies are best enjoyed slightly chilled or at room temperature.

Notes

  • Store in an airtight container for maximum freshness.
