  1. Step 1: Line a 9x9 inch square pan with parchment paper. In a bowl, combine 200 g crushed Tim Tam biscuits with 100 g melted unsalted butter, stirring until evenly mixed; press this mixture firmly into the base of the prepared pan.
  2. Step 2: In a small saucepan, gently warm 1/2 cup sweetened condensed milk and 1/2 cup caramel sauce over low heat, stirring for 2 minutes until combined and slightly thickened; pour this caramel layer evenly over the biscuit base and refrigerate for 30 minutes to set.
  3. Step 3: Heat 1/3 cup heavy cream in a small pot until just simmering, then pour over 150 g chopped dark chocolate in a bowl; let sit for 2 minutes, then stir until smooth and glossy.
  4. Step 4: Pour the chocolate ganache over the set caramel layer, smoothing the top with a spatula; refrigerate the slice for at least 2 hours until fully firm before slicing into squares to serve.
