A rum cake is a type of dessert cake which contains rum. In most of the Caribbean, rum cakes are a traditional holiday season dessert, descended from the holiday puddings (such as figgy pudding). Traditionally, dried fruit is soaked in rum for months and then added to dough prepared with sugar which has been caramelized by boiling in water. Finest Ingredients: Made from scratch without the crutch of cake mix, this vanilla rum cake is perfectly moist, extra buttery, and flavored with rum. Top with boozy butter rum glaze and serve warm or cold. Soft & Delicious Rum Cake: Each cake is wrapped in aluminum foil to preserve the aroma and freshness. That will also help to keep the softness of cake and its delicious taste. The cakes can be stored at room temperature. The cakes must be covered with aluminum foil or plastic wrap even when kept in a cake cover to retain its extreme moisture and freshness.
