McDonald's Australia has quietly launched a new TimTam McFlurry flavour - complete with a creamy vanilla soft-serve, caramel swirls and chocolate biscuit crumbs. Food blogger Adrian Widjonarko, from Sydney, discovered the $4 secret menu item called 'Choc Slam' McFlurry via the MyMacca's app. 'It is basically a TimTam McFlurry but they are calling it "Choc Slam" in their system! Chocolate biscuits crumbs and caramel swirl sauce,' he said. 'You must try this! Seriously so good! I want more now. You must give this a go.' Adrian made a 'public service announcement' in his now-viral TikTok video after he got to taste the new limited edition dessert.
