If you're from the UK, you may have come across a similar treat called tiffin or fridge cake. Believe it or not, tiffin is actually an Indian word meaning 'light snack', but over time in the UK it's come to mean a no-bake chocolate treat containing crushed biscuits, dried fruit, cocoa, golden syrup and butter. There aren't usually marshmallows in it like in rocky road. Fridge cake is just another name for tiffin! So rocky road is similar, but different. I also think it's easier to make, but just as delicious.
