Dark Chocolate Rocky Road

I made these cakes for a staff meeting, they are very rich so you only need a little piece, but they are yummy.

Dark Chocolate Rocky Road (adapted from BBC Food)
(Makes 24)

125g soft butter
300g dark chocolate, broken into pieces
3 tbsp golden syrup
200g digestive biscuits
100g mini marshmallows
80g crystallised ginger, chopped

Heat the butter, chocolate and golden syrup in a saucepan over a gentle heat.

Place the biscuits into a plastic freezer bag and crush them with a rolling pin until some have turned to crumbs but there are still pieces of biscuit remaining.

Fold the biscuit pieces and crumbs into the melted chocolate mixture in the saucepan, then add the marshmallows and ginger.

Tip the mixture into a 24cm x 24cm baking tin and smooth the top with a wet spatula.

Refrigerate for about two hours or overnight. Cut into bars.
