Nestle's previous attempt to specifically target the female market with a premium confectionery range, Little Notions, fell flat after it failed to find an audience.
Critics claimed the products, which featured stick-cartoon drawings on the packaging, were patronising and over-priced.
Aero Chocolate Truffle, which will be in stores from 6 February, will be sold as 42g bars, priced 45p.
It will be backed by an advertising campaign, including print ads in women's magazines.
According to a spokeswoman for Nestle, the launch is designed to 'target the key consumer trend for indulgent confectionery'.
In the year to 2 October 2005, Aero posted a 28.4% year-on-year increase in value sales, according to ACNielsen, making it the 10th-biggest chocolate brand in the UK.
The introduction of the truffle variant is the latest in a line of new product development for the brand.
Last year Nestle launched Aero Bubbles, peppermint-flavoured balls of chocolate, which compete head-to-head with Masterfoods' Maltesers. It has also extended into the hot-chocolate market (Marketing, 21 September 2005).
Nestle Rowntree has had a turbulent time in the past year, after its outspoken UK managing director, Chris White, left the company (Marketing, 9 November). He was replaced by Paul Grimwood, a former managing director of Nestle Purina Petcare UK.
