Ingredients

Instructions

  1. Step 1: Line a 20x20 cm square baking tin with baking paper. Melt 100 g butter in a saucepan over low heat. Remove from heat and stir in 200 g crushed digestive biscuits until evenly combined. Press the mixture firmly into the base of the lined tin.
  2. Step 2: In a separate saucepan, combine 1 can (395 g) sweetened condensed milk, 100 g brown sugar, and 2 tbsp golden syrup. Heat over medium-low heat, stirring constantly for 8-10 minutes until thickened and caramel-colored. Pour the caramel evenly over the biscuit base and refrigerate for 30 minutes to set.
  3. Step 3: Meanwhile, place 200 g chopped dark chocolate, 100 g chopped milk chocolate, and 100 ml whipping cream in a heatproof bowl. Microwave in 30-second bursts, stirring in between, until smooth and glossy. Pour the chocolate ganache over the set caramel layer and spread evenly.
  4. Step 4: Chill the slice in the refrigerator for at least 2 hours until fully set. Slice into squares and serve chilled.
