I'm not a fan of putting the fruit in mine, so I didn't.

2 large bars of chocolate
bag of small marshmallows
some digestive biscuits

2 large bars of chocolate

Break the chocolate up into small pieces in a large bowl. Microwave until melted.

Break up digestives until they are a fine crumb and add to the melted mixture, then add the marshmallows.

Mix until sufficiently integrated, then pour into a baking tray lined with foil or cling film (or glass dish, whatever fits) and place in the fridge to set.

After a few hours when it has set take out of fridge and its ready. To store, keep in an air tight container in a cupboard.
