The loaf, which aims to taste like a Christmas pudding, contains a mix of raisins, currants and cherries, along with citrus and winter spices.
The brand is also bringing back its limited edition individually wrapped Mini Loaves, which come in two flavours: Raspberry & White Chocolate, and Gingerbread.
Both the Christmas loaf and mini loaves are vegan.
Liz Jacobs, marketing director at Soreen, said: “The festive break is traditionally a time of indulgence for tasty treats and flavoursome snacks.
“However, we find families are also interested in healthier choices in the build-up to the holidays.
“Our Deliciously Snowy range provides the perfect combination, offering families a tasty treat that is low in calories, low in saturated fat and still retains that squidgy Soreen deliciousness to satisfy the taste buds either on-the-go, after or between meals.”
