Method
For the cheesecake, crush the biscuits in a plastic bag using a rolling pin. Melt the butter in a saucepan and add the crushed biscuits. Press the biscuits into a container using a tablespoon.
Melt the chocolate in a plastic bowl in the microwave. Beat the cream in a small bowl. Mix together the two types of cheese in a large bowl, and then fold in the whipped cream. Add the melted chocolate to the mixture and mix it in.
Add to the biscuit top and leave in the fridge to set.
For the ice cream, add the raspberries, caster sugar and yogurt to a tall jug and blend together until smooth. Then add to an ice cream maker, pouring it in slowly. Leave for roughly 30 minutes until ready for serving.
