Melt the milk chocolate and dark chocolate in a pot or microwave (be careful not to burn!).

Once the chocolate has melted and there are no lumps left add the syrup and marshmallows.

Crush the biscuits in a bag with a rolling pin. This is easier to do if you do small amounts of biscuits at a time. Then add the crushed biscuits to the mixture.

Put the mixture in a tray which has either been greased or has greaseproof paper in it. Put in the fridge for a few hours to set.
