First, make the gingerbread spice mix by combining all spices in a bowl. Set aside.
Place the milk and dark chocolate, butter, golden syrup and 2 tsp gingerbread spice mix in a pot over medium-low heat. Stir consistently until completely melted.
Remove from the heat, allow the mixer to cool slightly and add the gingerbread man pieces and marshmallows and mix until just combined.
Lightly grease 2 square aluminum containers in cooking spray and pour the mixture into both containers. Decorate with some festive sprinkles and gingerbread men icing toppers. Place these in the fridge (or freezer, if you’re in a rush) until set.
Slice the rocky road into bite-sized squares, and enjoy!
