The first of the new products to be launched, Highlights, will appear on the market this month.
An extension of the drinking chocolate range, the bar will have no added sugar and be marketed as a weight-control product at 160 calories per serving.
Dairy Milk Melts will be available in the autumn and are soft chocolates with a dairy milk shell sold in boxes of eight with three different flavours.
And, capitalising on the recent growth in the sector, a dark chocolate variety of the longstanding Flake brand will be launched in early October.
Managing director of the UK subsidiary Cadbury Trebor Bassett, Simon Baldry, said: "Our UK innovation pipeline is focused on delivering differentiated products that tap into emerging consumer trends. Ensuring innovation is at the heart of our strategy enables Cadbury Trebor Bassett to grow sales and market share."
According to Cadbury, the dark chocolate market in the UK is worth £160m (€234.39m) and is growing at an annual rate of 13 per cent. Their figures also show that 3 million new consumers have switched to buying dark chocolate in the last two years.
Dark chocolate accounted for 19 per cent of worldwide chocolate sales last year and is a rapidly growing trend in the industry due to its high levels of flavanols and antioxidants.
Other Cadbury developments include Roses Truffles - a box of 16 truffles in four flavours - and a new packaging design for the Snaps chocolate wafer products.
