Chocolate Flavour Icing. Cadbury Chocolate Icing is a deliciously creamy, ready-to-use frosting. It's perfect for adding the finishing touch to celebration cakes, Cadbury Chocolate Cake Mix or using as chocolate icing for cupcakes. This icing has all the chocolatey delight Cadbury is known for with no artificial colours or flavourings. Just stir, pop it into a piping bag and decorate your cake. Or spoon it out of the tub and spread it with a rounded knife for something simple and delicious. Whichever method you choose, you'll have a quick and easy treat, perfect for any time of the day. Keep a pot handy for fun baking sessions with the family (but try to stop everyone from eating it before it makes it to the cake)!
