Chocolate cornflake slice

By Sara Photography by Emma

My Mum used to make this slice when were growing up.  She complains that we have short memories when we tease her about her lack of cooking – and she is probably right.  Looking back, this slice was more often than not in a 1970’s mustard-yellow Tupperware container.  What can I say about it – the base is not too sweet and the cornflakes provide a satisfying crunch.  I have adapted the icing slightly, this whipped frosting is copied from my chocolate caramel slice post.


  • Base
  • 1 cup cornflakes
  • 1 cup self-raising flour
  • 1 cup coconut
  • 1/2 c sugar (I have halved this from the original recipe)
  • 1 heaped tbsp cocoa
  • 170g butter, melted
  • 1 tsp vanilla essence
  • Icing
  • 55g butter, softened
  • ½ c icing sugar
  • 1 tbsp cocoa
  • 1tbsp milk


      • --
      • 1. Preheat your oven to 180ºC on Bake.
      • 2. For the slice base, add melted butter to flour, coconut, sugar, cocoa and vanilla essence then mix.
      • 3. Add the cornflakes and mix again (not too much or you will over-crush them).
      • 4. Line a slice tin with baking paper and press the slice mix into the tin.
      • 5. Bake for 20 minutes, take out and leave to cool in the tin.
      • 6. For the chocolate icing, add the softened butter to the icing sugar and cocoa then beat. �
      • 7. Add the milk and beat further. If the icing is too thin, just add more icing sugar.
      • 8. Smooth the icing over the cool slice and refrigerate for at least 1 hour.
      • 9. Cut into squares.

          Sounds and looks delicious – brings back memories too, which I guess is what this series is all about!

          I love recipes where I’ll have all the ingredients on hand, as luck would have it this is one so there’ll be some chocolatey cornflakey goodness for me tomorrow and an introduction to a Kiwi classic for my little boy. Thanks!

          Because this has self raising flour in the base. Does it make it spongy a little bit more so than crunchy?

        4. Sara

          Interesting question; maybe the self-raising flour makes it a little lighter but it still has a crunch!
          It’s not really spongy and I really recommend you try it!

          Yay thank you for posting this! I used to eat cornflake slice as a wee one all the time thanks to my mum (we are both from christchurch). Every other cornflake slice recipe I found online had chocolate in it. :)

          It’s a part of my childhood too Jennifer as it was my mum’s go-to slice. Enjoy making it and then reminiscing, perhaps with a cuppa.

          Thanks for your comment,

          Will it still turn out ok if I just don’t use any coconut or can I sub it for something else? Thanks :)

        10. Sara

          Hi Lois, yes but you will need to reduce the butter quantity or increase the flour quantity to compensate.
          If you are looking for a substitute ingredient I suggest using bran flakes, quick-cook oats or even ground nuts.
          Happy cooking,

          Hello Sara, Thanks for this recipe-I can’t wait to make it also. Will be just the most yummy thing to share with my 94 year old Aunty- and a nice cup of tea.

          I am going to try this without the cocoa in the slice mix cos i remember a friend’s mum making something like this and i loved it. It was gold not brown on the bottom so hopefully……
