Ingredients
- 200 g, crushed digestive biscuits
- 100 g rolled oats
- 150 g, melted unsalted butter
- 1 can (395 g) sweetened condensed milk
- 150 g brown sugar
- 100 g golden syrup
- 60 g unsalted butter (for caramel)
- 200 g dark chocolate (70% cocoa), chopped
Instructions
- Step 1: Line a 9x9 inch (23x23 cm) square baking pan with parchment paper, leaving an overhang for easy removal.
- Step 2: In a large bowl, combine 200 g crushed digestive biscuits and 100 g rolled oats. Pour in 150 g melted unsalted butter and stir well until the mixture is evenly coated and crumbly.
- Step 3: Press the biscuit and oat mixture firmly into the base of the prepared pan to form an even layer. Place in the fridge to chill while preparing the caramel.
- Step 4: In a medium saucepan over low heat, combine 1 can (395 g) sweetened condensed milk, 150 g brown sugar, 100 g golden syrup, and 60 g unsalted butter. Stir continuously for 10-12 minutes until the caramel thickens and turns a golden amber color.
- Step 5: Pour the hot caramel evenly over the chilled biscuit base and return to the fridge for 1 hour to set.
- Step 6: Melt 200 g chopped dark chocolate in a heatproof bowl over a pot of simmering water, stirring until smooth. Pour the melted chocolate over the set caramel layer and spread evenly.
- Step 7: Refrigerate the slice for another 2 hours or until the chocolate is firm. Use the parchment paper overhang to lift the slice out of the pan, then cut into 16 squares to serve.
