Ingredients
For the Biscuit Layers
- 400 g (14 oz) tea biscuits or digestive biscuits
- 150 ml (⅔ cup) milk (for dipping, optional)
For the Caramel Filling
- 200 g (1 cup) granulated sugar
- 100 g (7 tbsp) unsalted butter
- 400 g (14 oz) sweetened condensed milk
- 1 tsp vanilla extract
- Pinch of salt
For the Chocolate Topping
- 250 g (9 oz) milk chocolate
- 2 tbsp vegetable oil or coconut oil
Instructions
Step 1: Prepare the Pan
- Line a 9×9-inch (23×23 cm) square baking pan with parchment paper.
- Arrange a single layer of biscuits on the bottom. Lightly dip each biscuit in milk if you prefer a softer texture.
Step 2: Make the Caramel
- In a medium saucepan over medium heat, melt the butter.
- Add the sugar and stir until dissolved.
- Pour in the condensed milk and add the salt.
- Stir continuously for 8–10 minutes until the mixture thickens and turns a rich golden caramel.
- Remove from the heat and stir in the vanilla extract.
Step 3: Assemble
- Spread one-third of the caramel over the first biscuit layer.
- Add another layer of biscuits.
- Repeat until you have three biscuit layers separated by caramel.
- Finish with the final biscuit layer on top.
Step 4: Add the Chocolate
- Melt the chocolate with the vegetable oil in the microwave (30-second intervals) or over a double boiler.
- Pour the melted chocolate over the top layer.
- Smooth it evenly with a spatula.
Step 5: Chill
- Refrigerate for at least 4 hours, or overnight for the best texture.
Step 6: Slice & Serve
- Remove from the pan.
- Use a warm, sharp knife to cut into squares.
- Enjoy chilled or let sit at room temperature for 10 minutes before serving.

Tips for Success
- Use high-quality chocolate for a smoother, richer topping.
- Let the caramel cool slightly before spreading to prevent the biscuits from shifting.
- Refrigerating overnight makes slicing much easier.
- Sprinkle a pinch of flaky sea salt over the chocolate before it sets for a delicious sweet-and-salty twist.
Storage
- Refrigerator: Store in an airtight container for up to 5 days.
- Freezer: Freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
Recipe Notes
- Add chopped roasted hazelnuts or walnuts between the layers for extra crunch.
- Swap milk chocolate for dark chocolate if you prefer a less sweet dessert.
- Serve with coffee, tea, or a scoop of vanilla ice cream for an extra-special treat.
