While on holiday in the United Arab Emirates (UAE) last week, there was only one mission on my mind - getting my hands on the viral "Dubai chocolate" bar.

If you're on TikTok, you will have seen the bar, which combines the flavours of chocolate, pistachio and tahini with filo pastry, and is inspired by the Arab dessert Knafeh.

The original, called Can't Get Knafeh of It, by FIX Chocolatier, has been sold exclusively in the UAE since 2022. It become so popular on social media that it's only on sale for two hours a day and often sells out within minutes.

But now imitations, known by the nickname "Dubai chocolate", have hit UK supermarkets including Waitrose, Lidl and Morrisons, with some supermarkets limiting the number of bars customers are allowed to buy.

Yezen Alani, who co-owns FIX with his wife Sarah Hamouda, told the BBC the global attention Dubai chocolate was getting was "flattering and humbling".

The FIX chocolate bar was first imagined by Hamouda in 2021, who craved the flavours while she was pregnant.

Alani and Hamouda started developing the bar a year later, running the business alongside their corporate jobs.

"Sarah and I were brought up in the UK and we moved to Dubai 10 years ago, so we've got Western and Arab roots.

"We wanted to create flavours that were inspired by that," Alani says.

Part of the appeal of the chocolate is its exclusivity - you........
