The original recipe is from "The Ultimate Cookie Book" but I modified it a little bit with the chocolate topping! Drizzling the white chocolate on top reduces the bitterness of the bar so they're more manageable.
They are most definitely the ultimate studying/library snack for people who have revision or essays to write. They're also really good for when you don't have much time to bake anything; just mix all of the ingredients together then chill in the fridge, and voilà rocky road bars are all yours!
115g dark chocolate
2 tbsp caster sugar
2 tbsp golden syrup
2 tbsp cocoa powder (I used Bournville)
350g mixed digestive biscuits and ginger nuts
50g mini marshmallows
75g mixed white and milk chocolate drops
75g milk chocolate
75g white chocolate
1) Line a 20cm square cake tin with baking parchment.
2) Place the butter, dark chocolate, sugar, syrup and cocoa powder in a pan and heat gently until completely melted.
3) Put the biscuits into a large plastic bag and crush to coarse chunks with a rolling pin then add to the chocolate mixture.
4) Add the marshmallows and chocolate chips and mix well.
5) Spoon the mixture into the square tin but don't press down too much.
6) Melt the white chocolate and milk chocolate in two separate bowls over a pan of boiling water then drizzle over the top of the rocky road.
7) Leave to chill for an hour or more in the fridge.
8) When set, cut into bars.
