Ingredients

Instructions

  1. Step 1: In a large mixing bowl, combine 200 g crushed digestive biscuits, 100 g desiccated coconut, and 2 tbsp sifted icing sugar. Pour in 200 g sweetened condensed milk and 100 g melted butter, stirring with a spatula until mixture is sticky and well combined.
  2. Step 2: Line an 8x8-inch square baking pan with parchment paper. Press the biscuit mixture evenly into the base of the pan, compacting it tightly with the back of a spoon. Refrigerate for 1 hour to set firmly.
  3. Step 3: To make chocolate ganache, place 150 g chopped dark chocolate in a heatproof bowl. Heat 100 ml heavy cream in a small saucepan over medium heat until it just begins to simmer, then pour over the chocolate. Let sit for 2 minutes, then stir gently until smooth and glossy. Stir in 1 tsp vanilla extract.
  4. Step 4: Pour the ganache evenly over the biscuit base and spread with a spatula to cover completely. Refrigerate for at least 2 hours or until ganache is set.
  5. Step 5: Remove the slice from the pan using the parchment paper edges. Cut into 12 squares and serve chilled.
