GRANOLA: Original granola was invented in New York as a mixture of crumbled graham flour. Nowadays it is typically made with rolled oats and a variety of added ingredients including fruit, nuts, chocolate, syrup and more, for a delicious healthy breakfast! Very similar to muesli cereal.
CRUNCHY HAWAIIAN: The finest oats are milled and toasted in our unique way – we then combine them with juicy raisins, tropical banana and pineapple pieces to create the tastiest, crunchiest granola clusters. Enjoy cold, hot, with dairy milk, almond, soya, oat milk, as a crunchy yoghurt topping or simply as a snack, whatever is your preference!
BENEFITS: High in fibre, No added salt, contains wholegrain & helps to actively lower cholesterol when consumed as part of a varied balanced diet and a healthy lifestyle. Oat beta glucans have been shown to help lower blood cholesterol
SUSTAINABLE: At Mornflake we are committed to help protect the world's rainforests from deforestation. We make sure that all ingredients used for our products are sourced responsibly
ABOUT US: Our family has been milling oats in South Cheshire since 1675, making us Britain’s fourth-oldest family-owned company. Today, 15 generations later, we are still independent and just as passionate about providing you with a great-tasting, great-value breakfast using the finest-quality oats
