Line a 8x8" with baking paper/ parchment paper and set aside.
In a large bowl, add your chocolate and lemon flavouring and melt in the microwave in short bursts. Stir thoroughly each time until smooth.
Once it's melted and combined, add in the mini marshmallows, chopped digestive biscuits and mix until everything is coated in the chocolate mixture.
Pour your mixture into the tin and spread until it’s even (I like to flatten mine down using baking paper to ensure it is compact and not crumbly!)
Spoon some lemon curd on top and slightly swirl through.
Melt your white chocolate in a microwaveable bowl in short bursts (20 seconds) and stir well in between as white chocolate can burn quite quickly.
Pour your white chocolate on top of the rocky road and spread it out evenly. Swirl through some more lemon curd, sprinkle some mini marshmallows, meringues and digestives on top and set in the fridge for 3 hours or until firm.
Once set, slice into slices. I sliced mine into bigger chunks so I got 9 slices but these rocky roads are moreish so you could slice them into smaller chunks and get 18 pieces!
