Ingredients You’ll Need

Step-by-Step Instructions

- Mix in the fillings– Stir in biscuits, marshmallows, Reese’s Pieces, and chopped brownie chunks until evenly coated.
- Press into tin– Pour mixture into a lined baking tin, pressing down gently to create an even layer. Add your melted chocolate layer and add your decoration toppings such as brownie chunks, biscuits, marshmallows and reeces pieces.
- Chill– Refrigerate for at least 2 hours until set.
- Slice & enjoy– Cut into squares or bars and serve your Peanut Butter Rocky Road!
Tips & Tricks for Perfect Rocky Road
- Use dark chocolate if you prefer a richer flavour.
- For a Halloween twist, add spooky sprinkles or candy eyes!
- Store in an airtight container in the fridge for up to 1 week.
- Don’t overheat the chocolate– Melt slowly over low heat or use a microwave in 20-second bursts. Overheating can cause the chocolate to seize.
- Balance the sweetness– If you find this recipe a little too sweet, swap some milk chocolate for dark chocolate. The bitterness balances out the marshmallows and peanut butter.
- Add crunch– salted peanuts can give an amazing crunchy texture.
- Storage tip– Keep rocky road in the fridge for the best chewy texture, but let it sit for 5–10 minutes at room temp before serving for the perfect bite.

Peanut Butter Rocky Road
Ingredients
- 400g Milk Chocolate
- 100g Golden Syrup
- 100g Unsalted Butter
- 150g Peanut Butter
- 200g Chopped Digestives
- 100g Mini Marshmallows
- 100g Chopped Brownies
- 100-200g Reeces Pieces

Instructions
- Line a 9" square tin with baking paper/ parchment paper and set aside.
- In a large bowl, add your chocolate and peanut butter spread and melt in the microwave in short bursts. Stir thoroughly each time until smooth.
- Once it's melted and combined, allow it to cool slightly. Add in the mini marshmallows, chopped brownie, chopped 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!)
- Melt your milk chocolate in a microwaveable bowl in short bursts (20 seconds) and stir well in between.
- Pour your milk chocolate on top of the rocky road and spread it out evenly. Swirl through some peanut butter spread, sprinkle with crushed biscuits and reeces pieces 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!
