These chocolate cornflakes squares are so simple and easy to make. They require minimal work and there is no baking involved. They are my go-to recipe when I need something quick, chocolatey and crunchy. I used to buy chocolate cornflake bites in the supermarket but recently decided to start making my own and I don’t think I will buy them from the shops again.

I use a mixture of milk and dark chocolate which I find prevents the cornflake squares from being too sweet. Most cornflakes cereals are fortified so you can also get some nutrients into your sweet treats. If you have kids, they will definitely love this recipe and they will enjoy getting involved to make the recipe. My daughter who is now 5 loves to help me in the kitchen and simple recipes like this are perfect.

We enjoy these crunchy treats as an afternoon snack or as a after dinner treat but they're perfect for any time of day. If you ever want to whip up a sweet treat in less than 10 minutes then this is the perfect recipe.
Ingredients for Chocolate Cornflakes
- 200g cornflakes
- 60g unsalted butter (soft at room temperature)
- 200g milk chocolate (chopped)
- 100g dark chocolate (chopped)
- Sea salt (optional)

How to Make Chocolate Cornflakes
1. Line an 20 x 20 cm (8 x 8 inch) baking tin with parchment paper with enough parchment to hang over the edges of the tin. Set the tin aside.
2. Add the cornflakes to a large bowl and using your hands, crush the cornflakes into smaller pieces. Also set aside.
3. Melt the chocolate by placing a heat proof bowl over a pot of boiling water. Ensure the bottom of the bowl isn’t touching the water. To the bowl, add the butter, milk chocolate and dark chocolate. Stir until melted. You can also melt in the microwave.
4. Pour the cornflakes into the melted chocolate and butter then stir until all the cornflakes are coated in chocolate. As you’re stirring, crush the cornflakes into the chocolate to make the cornflake pieces even smaller.
5. Once all the cornflakes are coated, tip the mixture into the tin and use a spatula to smooth it out and press tightly into the tin. Set in the fridge for 1 hour then remove from the tin using the parchment paper overhang. Cut into 16 squares by cutting the whole thing into 4 pieces then cutting each piece into 4 again.
Recipe Tips
- For this recipe, I use an 20 x 20 cm (8 x 8 inch) baking tin.
- I use a mixture of milk and dark chocolate but you can use all dark chocolate or all milk chocolate.
- Remove the butter from the fridge a few hours before making this recipe. This isn’t essentially but it helps the butter to melt into the chocolate easier.

Storage
Store these chocolate cornflake squares in an airtight container. You can store them at room temperature if the weather isnt too hot. If you want them to be firmer then store them in the fridge. I usually consume them within a week.
