  • 1-2 tsp icing sugar


  1. Line a 20cm x 20cm brownie tin with foil. Crumble the biscuits and the walnuts into a large bowl (you want a good mixture of pieces and fine crumbs). Snip the marshmallow into halves or quarters with scissors and add those to the bowl too. Set aside.

  2. Put the butter and golden syrup in a saucepan and heat gently until the butter has melted. Put the chopped chocolate in a heatproof bowl then pour the melted butter and syrup mixture over it and leave to sit for a couple of minutes without stirring. Now stir until the chocolate is smooth and has melted then pour the whole lot over the biscuits and marshmallows. Stir to coat all the pieces in the chocolate then pour into your prepared tin in an even layer. Don’t press it down too much, you want quite a bumpy 'rocky road' surface. Leave to set in the fridge for 1-2 hours or overnight then dust with icing sugar and chop into bars or squares to serve. Keeps in the fridge for up to a week.

Currently on lockdown so it was a case of what was in the cupboard. I didn't have enough marshmallows so added in some dried cranberries. Used 300g milk chocolate and 50g dark chocolate. Whatever the combination, it's chocolate! What's not to like?

Quick to make (without chilling in the fridge) and nice rich taste. Dark chocolate brings the flavour really well, I think it's good to use 70% or over dark chocolate.

Loved this recipe so easy to make, took it on a picnic and it didn't last long. Didn't have any walnuts so made it without and it was fine. Will be making it again.
