You will need

Cupcake cases - you can buy these in bulk - see more details here at Amazon .

Bun tin - this one has holes to bake 12 muffins or cupcakes - see more details here at Amazon.

Get the kids to help out by weighing and measuring the ingredients, breaking the chocolate into squares before melting, and spooning out the mixture once it's cooled enough. You can also let their imaginations run wild by trying some of the variations below. Any kind of sweets, chocolates or fruits are fair game for this versatile treat!

Remember though, cooking with kids can get messy! Make sure everyone's wearing old clothes, and keep a careful eye on little ones while you're dealing with the hot, melted chocolate.

How long do cornflake cakes take to set?

The finished cornflake cakes will take at least half an hour to set in the fridge. If you can't wait that long, you can always eat one or two while they're still melty - we promise we won't tell!

How to store your chocolate cornflake cakes

Once they're cooled, they'll keep in an airtight container for 2-3 days - if you can resist eating them for that long! These treats are perfect for bake sales and gifts; just add a pretty ribbon and you're good to go.

Top tips for melting the chocolate

The best way to melt the chocolate is by using a small saucepan, and a glass bowl that fits into the top of the saucepan, without touching the bottom. Heat a little water in the bottom of the saucepan until simmering, and pop the bowl on top, making sure that the bottom of the bowl doesn't touch the water. Then just pop the chocolate in the bowl and keep stirring until it's all melted.

If you're in a hurry though, you can do it in the microwave. Just pop the chocolate in a microwave-friendly bowl, heat for 20 seconds and stir. If there are still lumps, heat for a further 20 seconds and stir again - repeat until all lumps are gone.

Why are my cornflake cakes soft?

It usually takes at least half an hour for the cakes to set fully. If they’re still soft after this time, consider leaving them in the refrigerator for a bit longer.

If your cornflake cakes turn out soft even after giving them time to set, you might need to adjust the proportions of ingredients in your cornflake cakes recipe. Too much chocolate or too little cereal can result in a softer cake.

Finally, make sure that you store your cakes in an airtight container once they’ve set to keep them crisp! Leaving them exposed to a humid environment can quickly make them soggy.

Where do cornflake cakes come from?

Cornflake cakes have been a staple children’s snack for decades! The recipe's simplicity and easy-to-find ingredients make it a popular choice for parents looking to involve their children in the kitchen.

We don’t really know when cornflake cakes were invented. One thing we do know for sure is that cornflakes themselves were invented in the late 19th century by John Harvey Kellogg (yes, of Kellogg’s fame!), so cornflake cakes can’t be much older than a century! 

How long do chocolate cornflake cakes last?

Once your chocolate cornflake cakes have cooled and set, they can be stored in an airtight container for 2-3 days. If you’re planning to gift them or bring them to an event, it's best to make them fresh on the day or the day before for the best flavour and texture.


For plain cornflake cakes, use a mixture of butter and golden syrup to hold the cakes together, as in our Rice Krispie treats recipe.

Try making some with milk chocolate, some with dark chocolate and some with white chocolate - which is your favorite?

You can mix up the cereal, too; cornflakes and Rice Krispies make classic treats, but try this recipe with whatever you have in the cupboard; you might be surprised by the results!

Add mini marshmallows for an extra sticky, chewy treat.

Get a few extra vitamins into your child by adding dried fruits such as raisins, dried apricots or freeze-dried strawberries.

As the treats are cooling, mould them into any shape you like - perfect for fancy Halloween and festive bakes.

If you’re looking for more posh cornflake cakes, it’s as easy as not skimping on the cornflakes! Don’t settle for the supermarket’s brand - get the better name-brand ones. They might be more expensive, but they’ll make a huge difference in the flavour and texture.

Chocolate cornflake cakes make ideal Easter nests - just top with a couple of mini eggs.

Why not make a giant cornflake cake ring and use instead of meringue for a decadent chocolatey pavlova-type dessert recipe?

Getting creative with decorations can make your cornflake cakes even more enjoyable, too! Turn them into festive treats by adding themed decorations such as edible Halloween and Christmas-themed toppers.

Cornflake cakes can also be dyed different colours using food colouring. Try creating a rainbow of treats that’ll delight your child and their friends - and other mums, too!

    Made these today, I think I used a wee bit more chocolate than the recipe, purely because of the way the bar was divided into squares. Dead easy to make, tasted amazing. My 3 year old did most of the work, I needed to blend in the cornflakes as I initially thought we didn't have enough coating, but it was spot on.

    My girls made these for me this morning (Mother's Day). They were so delicious, especially when they told me they had added special wishes as they stirred the mixture. I remember making these with my own mum, and they've not lost any of their appeal :)

    I've made these lots of times with my nephews. They are only 2 years old but the recipe is so simple (and tasty). They really love mixing the chocolate in.
