Cornflake Cake Ingredients
The only ingredients you need for these chocolate cornflake nests are cornflakes, butter, chocolate and golden syrup.

Chocolate
We prefer using milk chocolate as it's the children's favourite, but good quality dark chocolate, or even white chocolate can be used.
You don't need cooking chocolate for this recipe; your favourite brand will do the trick. However, cooking chocolate melts better, making combining it easier and quicker.
Golden Syrup
The golden syrup adds a sweet flavour to these crunchy cereal cakes; you could use honey maple or agave syrup.
Cornflakes
We have used a supermarket's own-brand cornflakes, but you can use any you like, including gluten-free cornflakes or try rice krispies or shredded wheat instead.
Toppings
We made our chocolate cornflake cakes with marshmallows on top, but they are customisable. You can top with anything you like!
At Easter you can make into a nest with ,mini chocolate eggs inside.
Instruction Tips
Here are a few key recipe tips for making chocolate cornflake cakes.
Breaking up the chocolate into smaller pieces is key for a smooth melt. The small size of the chocolate broken pieces ensures you don't seize or burn the chocolate. I also recommend chopping the butter into small cubes.
Let's look at how to melt the ingredients together. You have two options: melting in the microwave or a pan.
Microwave Method
Melting chocolate in the microwave is the quickest method. Here are a few tips for melting the butter chocolate and golden syrup together in a microwaveable bowl.
Changing the microwave settings to 50% power is best to prevent the butter and chocolate from exploding, spluttering or burning!
All microwave power varies, so start with 30 seconds at 50% power and stir.

Then, return to the microwave for 30-second intervals (still at 50% power) and stir. Repeat until everything melts together and is smooth.
Pan Method
As an alternative method, you can place the bowl over a saucepan filled a quarter full with hot water to create a bain marie.
Ensure the large bowl fits securely on top of the pan to prevent water from getting into it. Then, heat the saucepan over medium-low heat and add chocolate, golden syrup, and butter to the bowl.

Stir the mixture until smooth and well combined.
Whichever method of melting you choose, once the chocolate mixture has melted, add the cornflakes and gently stir all the ingredients together until well coated.

Be gentle here, folding the cornflake mixture over and over enough times to coat it with the delicious chocolatey mixture without crushing all the cornflakes.
Of course, if you let the kids make these chocolate cornflake cakes themselves, it won't matter if they get a bit squished! They'll still be delicious!

Cornflake Cupcake Cases
Transfer equal amounts of the chocolate-coated cornflakes into paper cupcake cases. The Cake Craft Company sells lovely cases.
Putting the cases into a cupcake tin helps keep the shape regular and prevents them from falling around while filling the cases.

More Topping Ideas
You can finish here… or add anything you like, such as mini marshmallows, smarties, M&M’s or raisins on top of the chocolate cornflake clusters.

Give the bowl to the kids to lick out now. That should keep them quiet while the cornflake cakes are setting.
Our kids love to make chocolate cornflake nests. Make a small hole in the middle to add mini eggs into, perfect at Easter time! For a more realistic looking, Easter nests, use crumbled-up shredded wheat instead of cornflakes.
How to Set
Your cornflake cakes are sloppy and soft at this point. The quickest way to fix this is to put them in the fridge to set. They shouldn't take long to firm up.
If the kids can't wait and want to eat them straight away, they can, but because the chocolate is still melted, they will be sticky and messy!

Serving Suggestions
Cornflake cakes are the perfect quick and easy recipe for school cake sales. We also have our simple cupcakes for Children in Need Day, another easy bake sales recipe.
It's also a great way to get kids involved in cooking, as they'll have fun making a nice treat to share with their friends.

Now let's be honest here: we are saying this chocolate cornflake recipe is for the kids, but even we adults love these rich, gooey chocolate-coated treats

The bonus is there is only one bowl and spoon to clean up after, unless the kids help you make them, then you will likely have sticky hands and chocolate faces to clean, too!
Storage
Once the cornflake cakes have cooled, they can be kept at room temperature in an airtight container for up to 3 days.

I wish I read this review before making them!
Mine turned out the exact same! 🙁
Kay says
Hi Rebecca im sorry to hear this.
Could you please give us more of descriptions of what they have come out like please as we need to get to the bottom of this problem, to remedy this asap.
Did your chocolate go lumpy before the cornflakes went in the bowl? I'm wondering if the chocolate was burnt in the microwave?
Lesley said they were slimy? Is this before they are set in the fridge or after?
We are going to make them again this weekend with the kids (they will be happy!)so we will see if we can problem-solve then. But would be nice to hear back from you with more details.
Thank you 🙂
Luke says
Hi Lesley, your the first person I have heard negatively from… We make these regularly for our children and never had a problem, in fact the hands in the photos are my daughters making it 😂. If the chocolate disintegrated I would think you overcooked it, it needs to be melted slowly on low heat, as written on the recipe? Once made they be sticky and gooey so you need to put them in the fridge to set, also stated on recipe card.
Cathy says
Is it ok to make these without kids? 😂😋
