- 250g (9oz) milk chocolate
- 100g (4oz) unsalted butter
- 5 tbsp whipping cream
- 1 tbsp golden syrup
- 400g (14oz) packet digestive biscuits
- 100g (4oz) white chocolate (optional)
- Break the chocolate into squares and place in a heatproof bowl with the butter. Set over a pan of simmering water and allow to melt. Remove from the heat and mix in the cream and golden syrup by hand, which will take a few minutes.
- Break the digestive biscuits into large chunks and gently fold into the chocolate mixture so as not to break up the biscuits too much. Using a spatula, transfer to a 900ml (1 1/2 pints) loaf tin that has been double lined with clingfilm, as this makes the cake much easier to lift out. Chill for at least 2 hours, though overnight is best.
- To serve, turn out the chocolate biscuit cake onto a platter. Break the white chocolate into squares, if using, and melt in a heatproof bowl over a pan of simmering water. Drizzle all over the chocolate biscuit cake and leave at room temperature to set for about 20 minutes before cutting into slices and arranging on plates.
