Tim Tam is a range of chocolate biscuits made by the Australian branded biscuit maker Arnott‚'s. Introduced to the Arnott‚'s collection in 1964, it came about when the Penguin bar was discovered in the UK and Arnott‚'s decided to create a better version. Australia‚'s favourite biscuits are often used to drink hot or cold beverages through them like a straw.
