  • 125 g unsalted butter
  • 1 cup 280g smooth peanut butter, plus 2 tbs extra to drizzle
  • 11/2 cups 225g plain flour, sifted
  • ¾ firmly packed cup 165g brown sugar
  • 1 cup 90g desiccated coconut
  • 1 egg beaten
  • 250 g good-quality dark chocolate chopped
  • 50 g white chocolate chopped
  • 50 g milk chocolate chopped


  • Preheat the oven to 180°C. Line a 20 x 30cm lamington pan with baking paper, leaving 4cm overhanging on all sides.
  • Combine the butter and peanut butter in a saucepan over low heat, stirring, for 1-2 minutes until melted. Place the flour in a large bowl with the sugar, coconut, egg and butter mixture and stir to combine. Press the mixture into the base of the prepared pan and smooth the surface. Bake for 10 minutes until golden (I had to bake for 10 minutes longer). Set aside to cool for 10 minutes.
  • Meanwhile, place the dark chocolate in a heatproof bowl set over a pan of gently simmering water (don’t let the bowl touch the water) until the chocolate has melted. Stir until smooth, then pour over the base and chill for 30 minutes until set.
  • Melt the white and milk chocolates in separate bowls as above. Whisk the extra 2 tbs peanut butter into the white chocolate until smooth. Drizzle slice with melted milk chocolate, followed by the white chocolate mixture. Chill briefly until set. Using the paper, lift the slice out of the pan and cut into 12 squares.
