For the slice base:

For the chocolate top:

  • 1 block milk chocolate 180g


  • 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.



  • Storage - Keep them in the fridge in an airtight container for up to a week. You can also cut them up into bite size pieces and freeze them. Perfect for snacks or lunch boxes just when you need it most!
  • Crushing Cornflakes - Use the back of a spoon to crush your cornflakes in a bowl. Or pop them in a bag and crush them up by hand, then pour them in a bowl ready to mix.
  • Triangles - We’ve been told these MUST be cut into triangles, but we won’t tell anyone if you decide to leave them as squares or long slices!
  • Ingredients Notes:
    • Butter - We used salted butter, but you can also use unsalted or margarine.
    • Self Raising Flour - If you don’t have self raising flour, sub with all purpose flour along with 1 tsp of baking powder and ½ tsp of baking soda.
    • Golden Syrup - This gives the slice a real caramelised taste along with the butter. You can also use honey, brown sugar or molasses as alternatives.
    • Caster Sugar - Any white sugar will work, or you can also use brown sugar.
    • Cornflakes - Crushed cornflakes make up the traditional crunchy base, but you can easily swap them for rice bubbles and weetbix.
