Chocolate manufacturers, it seems, are following the model of smartphone, tablet and TV makers by coming up with larger models of their products.

On Wednesday, chocolate maker King Cadbury said it will increase the weight and size of its flagship product, Dairy Milk, to 220 grammes from 200 grammes. However, the good news for chocolate lovers is that the recommended retail price of $4.49 would not go up.

But the decision to follow the recommended retail price is up to stores and grocers. Cadbury actually increased by 20 cents the current recommended retail price in February 2012.

When compared to 2009, the Dairy Milk was actually larger and heavier then at 250 grammes until Cadbury reduced the size to 200 grammes.

Cadbury's move is the reverse of what most consumer product manufacturers are doing, or cutting the sizes of the goods. The trend has been observed by shoppers for chocolates, ice creams, chips, cereals, soft drinks and cheese.

Among the known brands that had downsized their products in the past few years are Arnott's shapes, Mars bars, Smith's chips, Peters ice cream and Uncle Tobys and Kellogg's breakfast cereals.

Besides the bigger size, the Cadbury Dairy Milk also comes in a new package, more whole nuts and differently shaped chocolate pieces.

"We listen to our passionate chocolate lovers and when we realized there was a way for us to deliver more joy to thousands of Australians, we got straight to work," Cadbury General Manager for Marketing Ben Wicks said in a statement.

"As Australia's most love chocolate brand we are always looking to improve the eating experience. Joy is at the heart of everything we do. It is also behind these changes which reinforce our brand philosophy by multiplying the job for chocolate lovers," he added.
