Being a veggie, I had to miss out the marshmallows [otherwise I can't enjoy any of it myself - not having that! Although have found some veggie ones online..], but I used digestive biscuits, chopped mixed nuts and walnuts.
300g chocolate [dark, milk or a mixture]
3 tablespoons Golden Syrup
100g mini marshmallows [if you're using them]
Plus any other goodies you may want to add.
Heat the butter, chocolate and golden syrup in a bowl over some steaming water, stirring it as it melts.
Save about a third of your chocolate mix, as you'll need it later.
Put your biscuits in a bag, and crush them using a wooden rolling pin..not too much though, or the pieces won't be very chunky, and that's how you want them [or it's how I like them in my rocky road]!
Add your biscuits, marshmallows and any other treats to the chocolate mixture and stir it all in. Once everything is nicely coated, put it all into a tray, lined with greaseproof paper, and flatten down.
Pour the chocolate mix you left spare over the top and smooth over. Put it in the fridge for a good couple of hours, cut into squares and enjoy!
