Grease and Line a 9x9" square tin with parchment paper. Leave to the side for now!
In a microwaveable bowl, add your Toblerone, and milk chocolate and melt on a low heat until melted. You'll want to do 30 second bursts and stir in-between each time!
In a large bowl, add your chopped up digestives, and mini marshmallows.
Add 75% of the melted chocolate to your digestives and mini marshmallows and fold together.
Pour in to your tin, and smooth over. Pour the rest of the melted chocolate mix on top and smooth over as well. (This bit is optional, you can just mix it all together if you wish)
Chill the rocky road in the fridge for a couple of hours, and then chop up.
Notes
Toblerone is a naturally thinner chocolate in comparison to others because of the other ingredients. Because of this I don't often use butter and syrup in this mix, but you can if you wish!
Melt together 100g golden syrup, and 100g butter and mix in with the chocolate like in my other rocky road recipes.
This will last in the fridge for up to two weeks easily, if it lasts that long!
I used one of the large Toblerone bars which are 360g, and put in the other 250g of milk chocolate to make up a good weight of chocolate. You can use just Toblerone if you wish, but thats up to you!
