Line an 8" square tin with baking paper. I grease the tin first with a little butter to help the paper stick to it
Prepare a mixing bowl filled with the broken up Oreos, the marshmallows, and the glace cherries
Put the butter and white chocolate in a pan and melt together on a low heat, stirring together as it melts
Once it's fully melted and combined, take the pan off the heat and let it cool for 5-10 minutes
Pour almost all of the chocolate mixture into the mixing bowl of Oreos, marshmallows and glace cherries. and stir to fully coat the fillings with chocolate
Pour the whole lot into the lined tin, smooth down then add the remaining chocolate mixture to fill in any gaps
Decorate the top with more broken up Oreos
Put in the fridge overnight, or for 3-4 hours to set
Remove from the tin and slice into pieces. Store in the fridge for a firmer texture, or in a cool place for a softer texture
If you store the rocky road in an airtight container it can be kept for 1 - 2 weeks, and up to 3 weeks in the fridge. It is best kept in the fridge
