Ingredients

Instructions

  1. Step 1: Line an 8x8 inch square pan with parchment paper. In a bowl, combine 200 g crushed Tim Tam biscuits with 100 g melted unsalted butter and 1/2 cup sweetened condensed milk. Stir until evenly mixed.
  2. Step 2: Press the biscuit mixture firmly into the bottom of the prepared pan to form an even base. Chill in the refrigerator for 30 minutes to set.
  3. Step 3: In a small saucepan, heat 1/2 cup heavy cream over medium heat until it just begins to simmer. Remove from heat and pour over 200 g chopped dark chocolate in a heatproof bowl. Let sit for 2 minutes, then stir until smooth and glossy.
  4. Step 4: Pour the chocolate ganache evenly over the chilled biscuit base and smooth the top with a spatula. Refrigerate for at least 2 hours or until firm.
  5. Step 5: Before serving, dust the top lightly with 2 tbsp cocoa powder and cut into squares.
