Step 1

Preheat oven to 180C/160C fan-forced. Line a 20 x 30cm (base size) slice pan with baking paper, allowing the paper to overhang the 2 long sides.

Step 2

Place the butter and sugar in a large saucepan over medium heat. Cook, stirring, until the butter melts and the mixture is evenly combined. Bring to the boil. Cook, stirring, for a further 30 seconds or until thickened. Reduce the heat to low. Add the cornflakes and stir until well combined.

Step 3

Spoon cornflake mixture into the prepared slice pan. Use the back of a spoon to spread evenly. Place a sheet of baking paper over the top, then press paper to flatten mixture and cover any holes. Remove the paper and bake the slice for 5 minutes. Set aside for about 20 minutes to cool slightly.

Step 4

Place the chocolate in a microwave-safe bowl. Microwave on medium, stirring every minute, until melted and smooth. Pour the chocolate over the cornflake mixture. Use a palette knife to smooth the surface. Sprinkle with salt. Place in the fridge for 1 hour or until set.

Step 5

Lift slice out of the pan. Cut or break into shards to serve. Watch our step-by-step video below to see how to make our Cornflake crack recipe.
