Preheat the oven to 160°C conventional (140°C fan-forced). Spray a 12 hole muffin tray with non-stick spray.
To make the crust, crush the biscuits in a food processor, then add the melted butter and sugar and process until a fine wet crumb has formed. Push this into the base of each hole in the muffin tin.
Place all the cheesecake ingredients except the raspberries in a bowl and mix well. Gently fold the raspberries through, then dollop the mixture on top of the biscuit bases. Bake for 20 minutes, then leave to cool.

To make the topping, place the frozen raspberries and sugar in a saucepan over low heat for about 10 minutes, stirring occasionally, until melted. Squeeze in the lemon juice at the end.
