Platinum Bakery Rum Cake in a 130g single-serve pack is a moist, dark Caribbean fruit cake soaked with rum for the deep, traditional rum-cake flavour Caribbean households know — boozy, fruity, dense, with the long-soaked character that defines a proper Caribbean rum cake. The 130g size is the everyday single-serve pack. Particularly good at Christmas, special occasions, or as a small indulgence with coffee. Platinum Bakery is one of the established UK Caribbean bakery brands, and rum cake is one of the more traditional offerings in their single-serve range.
