In a large pan, gently melt 150g of dark chocolate, 50g of butter and 3 large spoons of Golden Syrup. The key here is gently, too harsh then the butter and chocolate will burn. Once it has melted then leave for 15 minutes. You need to leave it to cool down otherwise when you add the marshmallows they will melt.
Crush some gluten free biscuits. I used some gluten free shortbread from Tesco. I also added about 50g of gluten free rice cereal as well, for added crunch. Then add 50g of small marshmallows.
This mixture is then stirred carefully to ensure that all the ingredients are coated in the chocolate mixture.
Spoon the mixture into either a greased lined baking tray or a foil tray. Press down into the tray and ensure that it is evenly spread.
Then sprinkle the top of the rocky road with decorations. I used small marshmallows.
Chill in the fridge and then cut into squares or slices.
