Change is sometimes hard to swallow, especially in this case.

The Cadbury selection box is a Christmas staple, filled with a selection of chocolate treats ... but this year's offering comes with a side-order of controversy: The Fudge bar has been replaced and people are outraged.

Apparently, the decision-makers at Cadbury felt, like some others secretly felt, that the Fudge bar was over - and so decided to replace it with a Dairy Milk Oreo.

The sweet treat has been removed from the £2.99 box but is still available in the small (£1.09) and Freddo (£2.99) selection packs.

However, it seems they did not realise the divide the seemingly inconsequential decision would cause.

People have taken to social media to share their thoughts with the brand regarding the change - and it looks like more people actually liked the humble Fudge bar than we thought.

While people are still eating the new addition - obviously - they are not happy about it.

Apparently, this is not the first time Cadbury has switched out a favourite - but the removal of the fudge bar was the last straw for some chocolate lovers.

If you weren’t aware that chocolate, or a lack thereof, was capable of ruining Christmas, now you know.

Hopefully, the holidays can recover from this blow.
