Born in a home kitchen in Hertfordshire, Rollagranola was founded by Robin Longhurst as a response to ultra-processed breakfast cereals dominating store shelves. With a mission to prioritise whole food ingredients and functional nutrition, he developed recipes packed with nuts, seeds, and superfoods—no added sugar or empty carbs. Rollagranola now offers a range of baked granolas designed to energise, satiate, and nourish—whether used as breakfast, snack, or topper. Every blend balances flavour and fuel, turning the morning ritual into a moment of mindful nourishment.
