Available in two varieties - chocolate and caramel - each pot contains a chocolate sponge with the option of either a rich chocolate or caramel sauce underlayer, topped with a thick and creamy milk chocolate custard.
The desserts have been developed to be eaten either hot or cold, and can be heated in the microwave in less than 30 seconds.
Cadbury Custard & Sponge pots are packed in cardboard sleeves each containing two 110g pots of the same variant, with four twin-pot packs per case. The twin packs have a rrp of £1.58.
Müller is supporting the launch with in-store activity including sampling, posters, leaflets and pos material sited at point-of-purchase. There will also be initial introductory price promotions to encourage trial.
Chris McDonough, marketing and R&D director at Müller UK, says: "In developing the Cadbury dessert range we've been looking for a product which offers a real point of difference and which will open up a new opportunity for retailers. The popularity of traditional desserts continues to grow and we wanted to explore how Cadbury could play a role in developing this sector."
