Customers have been left gutted after Kellogg's revealed that it had discontinued its "best" cereal product.

Taking to the popular social media platform X, formerly Twitter, a customer asked where they could get their hands on a box of the Coco Pops Rocks as they hadn't seen any in a while.

Responding to the user, the brand said: "I’m sorry to disappoint you but this product has been discontinued. Perhaps I can interest you in our two new Coco Pops varieties, Coco Pops Mega Pops and Coco Pops Loops."

I wake up 10 minutes earlier everyday to eat these delights! I 100% recommend to everyone. So much better than Coco Pops. Yum."
