Arnott's Tim Tam Black Forest 175g - A Brand New Tim Tam Flavour..... we tried these last time we were in Australia and had to bring them back to the UK. The unofficial love child of a Wagon Wheel and a Tim Tam this is a must taste biscuit with an inside filling of marshmallows and cherry flavoured fudge combined with a dark chocolate coating all sandwiched on the famous twin Tim Tam biscuit.
