Ingredients

  • 150g white chocolate, finely chopped
  • 125g salted butter, cubed
  • 100g light brown sugar
  • 100g golden caster sugar
  • 3 large eggs
  • 130g tahini, well stirred, plus 1–2 tbsp extra for drizzling
  • 2 tsp vanilla bean paste
  • 85g plain flour
  • 150g milk chocolate chunks (reserve some for topping)
  • 1/2 tsp sea salt flakes
  • 1/2 tbsp toasted sesame seeds (white and/or black)

Instructions

  1. Preheat oven to 180°C (160°C fan). Line a 20cm square tin with parchment paper.
  2. Melt white chocolate gently in a heatproof bowl over simmering water. Set aside.
  3. In a saucepan, melt butter, then cook until browned and fragrant. Remove from heat.
  4. Stir both sugars into browned butter. Cool for 5–10 minutes.
  5. Beat in eggs one at a time. Stir in melted white chocolate, tahini, and vanilla.
  6. Fold in flour and most of the milk chocolate chunks. Pour batter into lined tin and smooth the top.
  7. Sprinkle remaining chocolate chunks and sea salt flakes on top.
  8. Bake for 25–30 minutes, until golden on top and set with a soft center. Cover loosely with foil if over-browning.
  9. Cool in tin for 5 minutes, then transfer to wire rack. Chill for at least 2 hours or overnight.
  10. Slice into squares. Drizzle with extra tahini and sprinkle with sesame seeds before serving.

Notes

  • Chilling is key for a fudgy, dense texture.
  • Always stir tahini before using to avoid oil separation.
  • Store chilled for firmer texture; serve at room temperature.
