Ingredients

Units Scale

Slice Base

  • 200 g salted butter
  • 1/2 cup caster sugar (100 g)
  • 2 tbsp golden syrup
  • 1 cup desiccated coconut (80 g)
  • 3 cups crushed cornflakes (90 g)
  • 1 cup self raising flour (150 g)
  • 1.5 tbsp cocoa powder

Chocolate Top

  • 1 block Cadbury milk chocolate (180 g)

Instructions

  1. Preheat: Preheat your oven to 180°C / 360°F to ensure it reaches the correct temperature by the time your slice base mixture is ready.
  2. Melt and Mix: Place a large saucepan over low heat and add the butter to melt. Once melted, stir in caster sugar, golden syrup, desiccated coconut, cocoa powder, and self-raising flour. Mix thoroughly until well combined.
  3. Add Cornflakes: Gently fold in the crushed cornflakes, mixing until evenly incorporated into the mixture.
  4. Press and Bake: Transfer the mixture into a 20 x 30 cm (8 x 12 inch) slice or glass baking tray. Using the back of a spoon or spatula, press firmly, especially into the corners, to create an even layer. Bake in the preheated oven for approximately 25 minutes.
  5. Cool: Remove the slice base from the oven and allow it to cool completely at room temperature.
  6. Melt Chocolate: Break the milk chocolate into pieces and place in a microwave-safe bowl. Melt in 30-second intervals, stirring between each session, until smooth and fully melted.
  7. Top and Set: Spread the melted chocolate evenly over the cooled slice base using a spatula. Refrigerate for at least 15 minutes to allow the chocolate to set firmly.
  8. Slice and Serve: Once set, cut the slice into desired shapes such as squares, triangles, or long slices. Serve immediately or pack as a convenient snack.

Notes

  • Storage – Keep the slices in an airtight container in the fridge for up to one week, or cut into bite-sized pieces and freeze for longer storage. Ideal for snacks or lunch boxes.
  • Crushing Cornflakes – Crush cornflakes using the back of a spoon in a bowl or place them in a bag and crush by hand before adding to the mixture.
  • Shape – Traditionally cut into triangles, but feel free to leave them as squares or long slices based on preference.
  • Butter – Salted butter is recommended but unsalted butter or margarine can be used as alternatives.
  • Self-Raising Flour Substitute – If unavailable, substitute with all-purpose flour combined with 1 tsp baking powder and ½ tsp baking soda.
  • Golden Syrup Alternatives – Can substitute with honey, brown sugar, or molasses for a similar caramelized flavor.
  • Caster Sugar Alternatives – White sugar or brown sugar can be used successfully.
  • Cornflakes Substitutes – Rice bubbles or crushed weetbix are good alternatives for the crunchy base.
