    This delicious Mint Rocky Road recipe is the perfect combo of soft marshmallows, crispy minty bubbles, and dark chocolate!

    Rocky Road is one of those versatile recipes that you can adapt to suit any taste. Take your favourite type of chocolate, whether that be white, milk or dark - or even Caramilk - then add all your favourite chocolate bars and sweets!

    There's the traditional rocky road, packed with marshmallows, peanuts, coconut and soft jellies, but if Clinkers, Maltesers or even licorice allsorts are your 'weakness', there's a rocky road recipe to suit everyone!

    Why You're Going To Love This Recipe

    Everyone loves a bite (or two.....or three.....) of rocky road!

    • Quick and easy recipe - Mint Rocky Road takes so little time to put together - the hardest part is waiting for it to chill!
    • Chocolate and mint combo - these flavours are made to go together, aren't they!? I've used dark chocolate here, Mint Slice biscuits (with their layer of peppermint cream), bubbles of Aero mint chocolate, mini marshmallows and Peppermint Crisp bars for a little extra 'crunch' factor!
    • Versatile - you can swap around ingredients if you like, maybe use Mint patties instead of Mint Slice biscuits. Try adding some Aero Peppermint Bubbles or Darrell Lea Minty Crunch BB's - you can often find them on special around Christmas time.
    • Homemade gift - a cute little bag filled with chunks of Rocky Road, and tied with a pretty ribbon, makes a gorgeous home made gift - and 'homemade gifts' always show that extra special touch.
    • Conventional and Thermomix- Mint Rocky Road can be made conventionally using a microwave or stovetop, or alternatively in a Thermomix. I have included both the conventional and Thermomix methods in the recipe card at the bottom of the post.

    What You Need

    I keep an eye out for when these chocolate bars and biscuits pop up on special at the supermarket!

    Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

    Ingredients for Mint Rocky Road on a bench top.
    • Dark chocolate melts - choose a quality brand of chocolate melts (I like to use Cadbury or Nestle). The chocolate is a main ingredient in this Mint Rocky Road recipe, so choosing a good one makes a difference!
    • Coconut oil - optional. Adding a little coconut oil to the chocolate when melting helps to stop the rocky road from cracking when cut into pieces.
    • Mini white marshmallows - these can usually be found in the baking section of the supermarket.
    • Mint Aero Bar, Arnotts Mint Slice biscuits, Peppermint Crisp Bars - all roughly chopped into pieces.

    Equipment Required

    Mint Rocky Road requires no baking and very little equipment!

    You will need:

    • Microwave, stove-top or Thermomix to melt the chocolate.
    • Large mixing bowl and spoon - and a saucepan if making on the stovetop.
    • 20cm x 20cm square baking tin (or similar size), lined with baking paper, to chill the Rocky Road in.

    Step By Step Instructions

    A perfect homemade treat or gift for family, friends, neighbours, teachers and more, all made in a couple of easy steps!

    Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

    Step 1 - Chop The Biscuits And Chocolate Bars

    Line the base and sides of a 20cm x 20cm square baking tray with baking paper.

    Chop the Mint Aero Bar, the Mint Slice biscuits and the Peppermint Crisp roughly.

    Step 2 - Melt The Chocolate

    Place the chocolate melts and coconut oil (optional) into a heatproof, microwave-safe bowl.

    Microwave uncovered, on 50% power, in 30 second bursts, stirring every time with a metal spoon, for 4-5 minutes or until the chocolate and coconut oil melts.

    Remove from the microwave and stir until smooth.

    Step 3 - Mix All Together

    Add the mini marshmallows, chopped Aero, Mint Slice biscuits and Peppermint Crisp bars to the melted chocolate.

    Chopped ingredients added to melted chocolate in a large bowl.

    Stir to coat all ingredients with the chocolate.

    Step 4 - Chill

    Spread the mixture into the prepared baking tray and place in the fridge for 2 hours or until completely set.

    Once set, use a sharp knife to cut into pieces (if you are having trouble cutting the Rocky Road, run your knife under hot water and then dry it completely before cutting - the heat will help to cut through the layer) - see FAQ's.

    Expert Tips

    Such a simple recipe, this Mint Rocky Road is totally irresistible and great for the kids to help with too (I doubt you will get any complaints about this one!), but here's a few little extra tips:

    • Coconut oil - this is an optional step, but by melting a little coconut oil with the chocolate, it will make the Rocky Road easier to cut once it has set.
    • Mint chocolates - I chose to use a combination of Mint Aero, Peppermint Crisp and Mint Slice biscuits in this recipe, however, you can substitute them with any of your favourite mint chocolates or biscuits. 
    • Don't overdo the add-ins - as tempting as it is to add extra marshmallows, chocolates and biscuits... please don't! Stick to the chocolate/add ins ratio to ensure you have enough melted chocolate to thoroughly coat the add-ins.
    • Equipment - Mint Rocky Road can be made using a microwave, stove-top or Thermomix. If using a stove-top, melt the chocolate and coconut oil (optional) in a small bowl over a saucepan of boiling water (do not allow the water to enter the chocolate bowl).
    • Storing - this minty Rocky Road can be stored in an airtight container in the fridge for up to 1 month - I guarantee it won't last that long though!
    • Freezing - store in an airtight container for up to 3 months. Thaw Mint Rocky Road in the fridge overnight.

    FAQs

    How do I stop the chocolate from cracking when cutting it?

    Firstly, by adding a little coconut oil to the chocolate when melting, it will make the chocolate easier to cut through once it has set.
    Secondly, remove Mint Rocky Road from the fridge for 30 minutes to allow it to come to room temperature. Using a large sharp knife, run your knife under hot water and then dry it completely before cutting. The heat in the blade will help to cut the slice evenly! Check out my top tips for cutting here. 

    What sort of chocolate should I use for Mint Rocky Road?

    I recommend using a quality brand of chocolate melts in this recipe, as they are specifically designed for melting. Chocolate chips are not suitable, as they are made to hold their shape when heated, like in chocolate chip cookies.
    I like the flavour combo of dark chocolate with mint too, however you could use milk chocolate or white chocolate if you prefer.

    Notes

    RECIPE NOTES & TIPS
    Ingredients Info: 
    • Chocolate - I like to use dark chocolate for my mint rocky road recipe. However, you can substitute with white or milk chocolate if you prefer. Choose a high quality chocolate for melting (I like to use Cadbury, Lindt or Nestle). The chocolate is the main ingredient in this recipe, so choosing a good one makes all the difference.
    • Coconut oil - add a little to your chocolate when melting it - this will help with cutting into neat slices.
    • Marshmallows - choose mini white marshmallows for this recipe or use a combination of pink and white.
    • Mint Chocolates - I used a combination of Mint Aero, Peppermint Crisp and Mint Slice biscuits in this recipe, however, you can substitute them with any of your favourite mint chocolates or biscuits. 
    • Don't overdo the add-ins - as tempting as it is to add extra marshmallows, chocolates and biscuits... please don't! Stick to the chocolate/add ins ratio to ensure you have enough melted chocolate to thoroughly coat the add-ins.
    More Recipe Tips: 
    • Slicing - remove the Rocky Road from the fridge at least 30 minutes before slicing - this will help it to stop cracking. Use a large sharp knife to cut the rocky road (or check out my top tips for cutting rocky road here).
