United Biscuits UK has added a caramel wafer to its McVitie’s Penguin range, available in a nine-pack, to sit alongside the existing Penguin Wafer.

"The introduction of McVitie’s Penguin Wafer has been one of our most successful brand extensions in recent years," said brand director Matt Brown. "The new caramel-flavoured addition is the second most popular flavour in the wafer segment, after chocolate." The product contains 160kcal and has no hydrogenated vegetable oil, artificial colours or flavours.
