    I’m not sure how more than half of May has already passed and I haven’t posted yet this month. Blame all the kids parties and clubs as well as being really busy at work I guess.

    Even though I mostly work from home now this doesn’t mean I spend all day popping in and out of the kitchen baking sadly!

    This M&M rocky road was popular when I posted a picture on Facebook so I’m posting the recipe at last.

    Rocky road

    Rocky road is a delicious no-bake made from chocolate, marshmallows, broken biscuits and sometimes chopped nuts or cherries.

    Rocky road is perfect for a crowd so when I realised there was a school bake sale coming up, it was rocky road I decided to make.

    It is an excellent choice to make when the weather is warmer, as of course no baking is required!

    Cut it up into small squares, and as well as making these a bit less unhealthy for the kids (as they aren’t so huge!) it means the school can sell more and raise more money!

    I have a well stocked baking cupboard naturally (!) and already had the dark, milk and white chocolate and the marshmallows to hand.

    I just had to get the digestives and M&Ms so after a quick trip to stock up then I was able to get down to making the rocky road.

    I chose chocolate M&Ms for their bright colours and of course as this was for the school it couldn’t contain peanuts.

    M&M rocky road decorated with bright M&Ma.

    For the chocolate I used milk chocolate for the base layer mixed with the marshmallows and digestives, then topped it off with dark chocolate swirled with white chocolate to add a pretty effect.

    This adds a bit more colour and decoration as well as being a great excuse to use more chocolate!

    Ingredients

    Here’s what you will need for this recipe, quantities are in the recipe card below:

    • mik chocolate
    • golden syrup
    • butter
    • digestive biscuits
    • mini marshmallows
    • chocolate M&Ms
    • dark chocolate 
    • white chocolate

    Method

    1. Melt together the milk chocolate, golden syrup and butter (I do this in the microwave on a medium setting).
    2. Add the crushed digestives and mix well. Leave to cool for a few minutes before adding the mini marshmallows.
    3. Add half of the share bag of chocolate M&Ms.
    4. Press the mixture into a tin lined with baking paper.
    5. Melt the dark and white chocolate in separate bowls, pour over the mixture in the tin and marble the dark and white chocolate together with a knife. 
    6. Spread the remaining M&Ms on top. Chill in the fridge until set, at least for 2 hours but preferably overnight if you have time.
    7. Cut into squares using a large knife. Serve or wrap and transport to your bake sale!

    Troubleshooting

    If your mixture splits (i.e. goes thick and grainy and may separate into oil and solids) while heating in the microwave, add a little milk and stir well to bring it back together.

    Use a lower heat to avoid it happening again.

        Sorry to hear that. For future reference, you can usually fix this, which is normally caused by overheating or adding something cold to warm chocolate, by adding a little milk and mixing well.

      I adore rocky road, so it’s just as well I wasn’t around to snaffle rather more than would be good for me. Bet it sold fast. Thanks for sharing with #WeShouldCocoa. Pinned.
