Little-known fact about KitKat bars remerges, leaving many ‘confused’

KitKat fans have had their minds blown after discovering the popular chocolate block contains a filling nobody knew existed.

Chocolate lovers have had their minds blown over a little-known detail about the beloved KitKat.

The popular choccie treat, which comes in a unique four finger block you can snap, is famously made up of Nestlé chocolate and wafer.

But a resurfaced clip from a 2015 doco that reveals there’s more to the snack bar than meets the eye has left consumers both confused and amazed.

During an episode of the BBC’s Inside the Factory series, cameras went into the Nestlé factory in York, northern England, to show how KitKats were made.

Cameras capture an employee pulling off damaged bars and throwing them into a large blue bucket, prompting the host to ask: “What happens to all the ones you’re throwing away?”

She replied by explaining the broken bars all go into “rework” to be used for the “fillings for the wafer”.

This little nugget of information has left social media users “stunned” – with many revealing they had no idea KitKat bars had a filling.

Nestlé Australia’s head of marketing Joyce Tan confirmed the remarkable fact to news.com.au, explaining chocolate and wafer pieces are “mixed together with other ingredients to create a delicious praline used between the wafers in KitKat bars”.

“It’s both scrumptious and eliminates the waste during KitKat production,” she added.

YouTuber Zack D. Films went into a little more detail in a recent YouTube video, explaining it’s a great way of tackling food waste.

“Some KitKats get broken while they’re being made, and instead of throwing them out, the company crushes them up and adds sugar,” he said.

“And that’s what’s inside of a KitKat bar – it’s literally crushed up KitKats.”

The comments section on the video, posted on Sunday, has blown up with many stating it left them with more questions.

“So then… what was the original KitKat bar made of???” one wrote.

“I’m now in an infinite loop trying to figure out what came first,” another said.

While one stressed: “It’s just a loop of KitKats that never ends.”

One user however, summed up the complex discovery perfectly, writing: “There is a KitKat that is made from a KitKat that had a KitKat inside of it that was made of crushed up KitKats that had KitKats in them made by KitKats.”

Earlier this year, the chocolate bar announced a big change to its iconic red wrapper, revealing it would now be made using 30 per cent recycled plastic and would be 100 per cent recyclable.
