How to Make Cornflake Choc Nut Slice

  1. Preheat oven to 350°F (175°C). Grease and flour a 23cm square baking pan.
  2. Line the base and sides of the pan with baking paper, leaving some overhang to help with lifting out the slice later.
  3. In a heatproof bowl set over a pan of simmering water (double boiler), melt the chopped Mars bars, 100g butter, and peanut butter together. Stir until smooth and well combined.
  4. Remove from heat and transfer the melted mixture to a large bowl. Stir in the sifted icing sugar until fully incorporated.
  5. Gently fold in the lightly crushed cornflakes (or Rice Bubbles) until evenly distributed.
  6. Firmly press the mixture into the prepared baking pan, ensuring an even layer.
  7. In a separate heatproof bowl set over a pan of simmering water (double boiler), melt the chocolate and 2 tablespoons of butter. Stir until smooth and glossy.
  8. Pour the melted chocolate evenly over the cornflake mixture in the pan and spread to create a smooth top layer.
  9. Refrigerate for at least 4 hours, or preferably overnight, to allow the slice to set completely.
  10. Once set, lift the slice out of the pan using the baking paper overhang. Cut into rectangles and serve.
