Pre-heat your oven to 180°C / 360°F.
Pop a large saucepan on low heat. Add in the butter and melt first. Then pop in your sugar, golden syrup, coconut, cocoa and self-raising flour. Mix well until combined, then add in the crushed cornflakes last and mix again. Finally, pour into a slice tray or glass baking tray 20 x 30 cm / 8 x 12 inches.
200 g butter, ½ cup caster sugar / superfine sugar, 2 tbsp golden syrup, 1 cup desiccated coconut, 1 cup self raising flour, 1.5 tbsp cocoa, 3 cups cornflakes
Using the back of a spoon or spatula, press firmly and flatten (especially into the corners) then pop in the oven and bake for around 25 minutes.
Remove from the oven and allow to cool.
Once cooled, break up the chocolate in a bowl and melt in 30 second intervals in the microwave, stirring between each session. Once completely melted, layer with a spatula on top of the slice and place in the fridge to set.
1 block milk chocolate
Allow to set for a minimum of 15 minutes, before removing and slicing into squares, triangles or slices, ready to eat straight away or pack for a lunch snack.
