If there's one thing M&S does well, it's taking an already indulgent chocolate bar and making it even more delicious. Enter: its latest Choc Marks creation, which is packed with so many flavours and textures that it feels like a fully loaded dessert than a boring chocolate bar. And judging by our reaction when we tried it, you'll want to grab one ASAP.

Made in Switzerland (good start), the Salted Blond Chocolate, Pistachios, Shortbread & Cornflakes bar combines... well... everything really! Creamy caramelised blond chocolate, crunchy Californian pistachios, buttery shortbread chunks, crispy cornflakes and a sprinkling of sea salt. The cornflakes really turn it into something special. It's a crunch unlike any other. This bar is the perfect combination of sweet-and-salty, rich, crunchy and seriously creamy.

FYI, it's very chunky. But that word given to a chocolate bar is definitely a compliment. Every square is generously studded with pistachios, biscuit pieces and crunch cornflakes, giving it plenty of crunch alongside the smooth, buttery blond chocolate.

And shoppers are snapping it up too, with fans raving about it online. As soon as we tasted it, we knew that all our willpower would be gone. Do not give us a bar of this if we're trying to be 'healthy' because we will not be able to stop.

Other fans described it as "the ultimate sweet treat," while plenty of others admitted they were heading straight to M&S after spotting the bar on social media. The bar has already proved so popular that M&S recently introduced a smaller 50g version, making it even easier to grab as an on-the-go treat rather than committing to the larger sharing block.

The Choc Marks Salted Blond Chocolate, Pistachios, Shortbread & Cornflakes bar is available in M&S Foodhalls now, with the 50g bar priced at £1.45 and the larger sharing block (180g for £3.50) also available in stores and through Ocado.
