Chocolate Peanut Butter Cornflake Slice 

Chocolate Peanut Butter Cornflake Slice 

Ready for a slice of chocolate peanut butter cornflake slice? As you can see, my healthy eating post-holiday is going well! It was definitely time for a treat.

No baking needed, just some time to chill the layers, and you can help yourself to a slice of this.

You don’t need any fancy equipment, just a tray of some kind to make it in (I used a loaf tin) and bowls for melting and stirring.

A yummy treat for the kids before they go back to school perhaps? Or for yourself if you are anything like me. It isn’t difficult, it is just full of chocolate peanut butter goodness.

Start with a layer of cornflakes and chocolate as if you were making chocolate cornflake cakes. Let it chill in the fridge.

Top with a layer of peanut butter – sweetened up a little of course! Allow to set again, then top with melted dark chocolate.

And there you have it, a whole lot of yumminess you need to slice up straight away and share out.

Baking is fun but no-bakes are great for when you want something simple. it is rich and indulgent but just so easy and straightforward.

Bite through the top layer of chocolate to the creamy peanut butter beneath, and then reach the chewy cornflake layer at the bottom. A load of textures and a load of calories, clearly!

I just love the rich colour of the peanut butter. That creamy layer just makes this cornflake slice a bit more exciting!

Keep it in the fridge if it is warm weather to keep it at its best. See if you can stop at one slice. I find that a bit of a challenge.

What is golden syrup?


Looks yummy but would it work with milk chocolate do you think


Can I used honey instead?


How I convert this gr into a cup?


Love the recipe – although I forgot the icing sugar. Does this matter?


Could you convert the recipe to English measurements?


Can you make with other cereal

Oh yum this looks so tempting! I would definitely enjoy it. I just love how full of peanut butter and chocolate it is.

This looks so delicious, such great flavours and textures, pinning for later.

Oh my, these look amazing Lucy. Chocolate and peanut butter are a match made in heaven and chocolate cornflake cakes are one of my favourites. What a fantastic combination.
