Instructions

  1. Step 1: Preheat oven to 350°F. Mix 200 g crushed digestive biscuits with 100 g melted unsalted butter until evenly combined. Press mixture firmly into the base of a lined 9x9-inch square baking pan. Bake for 10 minutes until set and golden. Remove and cool slightly.
  2. Step 2: In a saucepan over medium heat, combine 1 can (395 g) sweetened condensed milk, 150 g brown sugar, 100 g unsalted butter, and 2 tbsp golden syrup. Stir continuously for 8-10 minutes until the caramel thickens and turns a deep golden color.
  3. Step 3: Pour the hot caramel evenly over the biscuit base, spreading smoothly. Refrigerate for 30 minutes to set.
  4. Step 4: Melt 200 g dark chocolate chips with 2 tbsp unsalted butter in a heatproof bowl over simmering water, stirring until smooth.
  5. Step 5: Pour melted chocolate over the set caramel layer and spread evenly. Chill in the fridge for at least 2 hours until firm before cutting into squares and serving.
