Chocolate Cornflake Crunch Bars with Coconut

A sophisticated version of the good old children’s favourite, chocolate cornflake clusters. The addition of coconut gives these chocolate cornflake crunch bars a delightful flavour and some chew as well as crunch.

We had a film night at a friends house a week or three ago and I needed something to take for us all to munch on. I needed something I could make the day before and that was easily portable.  The first book I took off the shelf to get inspiration was Bake by Rachel Allen. About three pages in, I saw the recipe for these chocolate coconut bars. Perfect, I had no more need to hunt. I recollected having seen them recently on another blog, but couldn’t remember whose they were. I do remember they had a good report though.

I changed the chocolate topping completely as I thought milk chocolate would work better than dark. I also added a bit of butter which makes it easier to spread the chocolate and gives it a little extra depth. As for the base, I mostly stuck to the original recipe, except I used wholemeal flour and baking powder.

The bars are quite quick and easy to make, though bashing the cornflakes can be a bit of a chore. On the other hand you might find it fun. I use the end of a rolling pin to crush the flakes. But placing them in a sealed plastic bag and bashing them that way also works.

This recipe is a sophisticated version of a childhood classic: chocolate cornflake clusters. They have a lovely crunchy texture and a nice combination of flavours with the coconut and chocolate. For avid bounty bar fans, this has to be a plus.  The base isn’t at all sweet, by which I mean it wasn’t too sweet and it was set off nicely by the sweeter chocolate topping.

For an even more sophisticated version, take a peek at this nutty cinnamon coconut chocolate crunch traybake.

These chocolate coconut cornflake crunch bars are ideal as picnic fare. They’re also perfect as emergency rations for a long cycle ride. Perhaps the calorie hit would be more deserved under those circumstances rather than slobbing out in front of a DVD. But hey, we enjoyed it.

Crunch Base

  • 3 oz cornflakes
  • 5 oz desiccated coconut
  • pinch of sea salt
  • 8 oz unsalted butter – softened
  • 5 oz golden caster sugar
  • 5 oz wholemeal flour
  • 1 tsp baking powder
  • 1 oz cocoa powder

Chocolate Topping

  • 6 oz good quality milk chocolate (I used 40%)
  • 1 oz unsalted butter


Crunch Base

  • Bash the cornflakes up in a large bowl until they’re large crumbs. I find the end of a rolling pin works well for this.
  • Add the desiccated coconut and salt, then stir until well mixed.
  • In another large bowl, cream the butter with the sugar until soft and fluffy.
  • Mix in the cornflakes and coconut.
  • Finally add the flour, baking powder and cocoa.
  • Stir together as best you can. This bit isn’t very easy.
  • Tip the contents into a 9″ square silicone mould or lined tin and press the mixture down with the back of a spoon until it’s firm and level.
  • Bake at 180℃ (350℉, Gas 4) for 20 mins.
  • Leave to cool.

Chocolate Topping

  • Melt the chocolate in a bowl suspended over a pan of hot, but not boiling, water. Remove from the heat.
  • Stir in the butter.
  • Spread over the base and leave to cool.
  • Cut into 16 squares.

    I’ve make these a few times and very much agree – they are not too sweet and an ideal ‘out and about’ treat.

    They sound great, and perfect for a bit of slobbing!!!!

    my mum made similar bars when I was young but with icing rather than chocolate on top – I think I would like them much better with chocolate – this sort of treat is good for those who take long bike rides but a dvd night deserves a few treats too

    I used to make these when my children were young, how these bars bring back memories.

    so simple and yet so lovely… maybe throw in some orange peel and you could Christmas them up a bit!

    You’ll be top of the invite list for my next movie night if you bring a batch of these along ;0)

    So reminiscent of slices we ate while growing up! The 3C combination: chocolate-coconut-cornflake is almost irresistible! 🙂

    I have always found choco and coconut as very earthy and heavenly combination …. awesome 🙂

    I wish I had friends that turned up with home baked treats like these when they come round my house.

    Most of my mates pop in to Tesco’s on the way for cheap plonk. I’m not moaning; the ones that don’t get cheap Tesco plonk just drive past and turn up empty handed.

    Gillian – would never have thought to bake with cornflakes if I hadn’t seen this recipe.

    BVG – a bit of slobbing is just what I’m about to do in a minute, but no nice bars to pig out on whilst doing it unfortunately!

    Johanna – have to guiltily admit that it’s a very long time since I’ve had a long bicycle ride.

    Maggie – worth making again and then you can really relive the memories.

    Dom – good idea and put a load of rum in the chocolate for good measure.

    Chele – thanks, always good to know I’m appreciated for my baking alone ;(

    Celia – I didn’t grow up with slices, I think it must be an antipodean thing.

    Ananda – you’re so right, some of my favourite chocolate is coconut flavoured.

    VBB – but you love them really.

    Slobbing out in front of dvd…some times it just has to be done. And what better way than to accompany it with a chocolate slice I say.

    Thanks CityHippy – always good to get slobbing endorsement.

    these sound delicious – and what a great way of using up the annoying cornflake crumbs from the bottom of the box!

    My grandsons would love these. I’ll make them next time they are coming, or maybe get them to help although that could be very messy!

      Yes get them to help. Getting messy in the kitchen at that age is part of the course.
