Ingredients

•250 g milk chocolate
•100 g unsalted butter
•5 tbsp whipping cream
•1 tbsp golden syrup
•400 g digestive biscuits
•100 g white chocolate

Cooking Instructions

1.
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.
15 min
2.
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.

3.
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.
