Australian biscuit baker Arnott’s has relaunched the white chocolate version of its Tim Tam biscuits after the company was inundated with letters from fans of the snack.

Fist launched in 1964, and named after the horse that won the Kentucky Derby in 1958, Tim Tams are, on a per capita basis, the biggest-selling chocolate biscuit in the world. Consisting basically of chocolate-coated biscuit fingers sandwiched together with cream, Arnott’s produces six varieties of Tim Tams (original, dark, double coat, chewy caramel and two limited edition varieties – white and hazelnut praline) at its Huntingwood bakery, near Blacktown.

The white chocolate variety was released as a special edition for Christmas 2000 and Arnott’s corporate communications manager Anna Burr told the Daily Telegraph: “We have received hundreds of requests to bring back white Tim Tams.

“For the past year, we’ve been receiving phone calls almost daily from people all wanting the same thing.”
