The ideal naughty treat to take on a picnic or a walk. Plus, it can be made days in advance - be warned, it won't last long!
175g pouch Maltesers
250g dark chocolate (70% cocoa solids), broken into pieces
8 digestive biscuits
60g baby marshmallows
Icing sugar to dust over
Gordon Ramsay suggests melting chocolate by breaking it up and putting it in the microwave on a low or defrost setting for a few minutes - just stir halfway through.
Line a 22cm-square tin with parchment paper.
Melt the chocolate with the butter in a bowl over boiling water until it has completely melted. Remove from the heat.
Set this aside to cool for at least 10 mins whilst you get the rest of the ingredients ready. It's important that the chocolate isn't too hot when it is combined with the other ingredients or it could melt the Maltesers and marshmallows and take the 'rocky' out of this recipe!
Next, bash up the biscuits in a plastic bag until you have a good mixture of chunks and powder.
Finally, add the crushed biscuits, marshmallows and Maltesers to the mixture and fold with a spoon until all are lightly coated in chocolate.
Pour into the tin to refrigerate for at least 30 mins. Sieve over a generous dusting of icing sugar.
