Double Decker

Double Decker is one of Cadbury’s long-running chocolate bars, and by our assessment its appeal comes from a very plain idea: wafer, caramel, and milk chocolate in a bar that is more about texture than drama. That layered bite is the thing people remember, because it gives you crunch and chew in the same mouthful. The downside is also part of the design; it is sweet, sticky, and built for a confectionery hit rather than a refined chocolate experience. In practice it is the sort of bar that feels old-fashioned in the best sense, with a no-nonsense shape and a filling that makes the sweetness stretch out. Against simpler plain chocolate bars, Double Decker is busier and heavier, closer to a snack than a neat square of chocolate. It fits people who want a filling sweet bar with something going on inside, and less well those who prefer clean, straightforward chocolate.
