100-200gdark chocolate*melted, optional, for topping
Lightly grease a 30 x 23cm tin.
Melt the syrup, butter and chocolate together (I do this in a heatproof bowl over a saucepan of hot water).
Remove from the heat, allow to cool slightly then add the crushed biscuits, walnuts and dried fruit and mix well. You want the chocolate mixture to be coating everything else.
Place in the roasting tin and press down firmly to level the surface and help it set. You could use a spatula to do this or place a sheet of baking paper on the top and press down with the palms of your hands.
If using drizzle melted chocolate over the top.
Allow to cool and then chill in the fridge overnight until set.
Cut into squares to serve and store in an airtight container in the fridge.
Use dairy free chocolate if vegan.
