Cornish artisan confectioner Buttermilk is launching its newest snack bar – an all butter bar of crumbly caramel sea salt fudge enrobed in Belgian milk chocolate!

The new snack bars are now available at BP forecourts, WHSmith and independent retailers across the whole of the UK, making them the perfect on-the-go treat for motorists and commuters.

The new bars are wrapped in a compostable cellulose wrapper which do not pollute the environment. Buttermilk has strived to find a new non-plastic wrapper made of plant-based materials that is hard-wearing, yet sustainable.

When the fudge has been enjoyed, the wrapper can be placed into a home compost bin and will decompose within 26 weeks at ambient temperature.

The new bars are a premium addition to the trend for 'on-the-go' snacking and join Buttermilk's line-up of more than 60 flavours which range from clotted cream to Cornish Gin and Earl Grey tea. The family-run firm's award-winning treats are still created using traditional recipes and methods at the company's production kitchen near Bodmin Moor.

Buttermilk managing director Tracy McDonnell Goad said: “Sustainability is an important part of Buttermilk's ethos and we were keen to find a plastic-free solution so that customers can enjoy an on-the-go treat, knowing that the packaging will not end up in the oceans. Being based in Cornwall means we're surrounded by beaches so we see first-hand the importance of incorporating environmentally-sustainable packaging materials. We very much believe customers will agree with us that this is a step in the right direction.”
