Pour your dairy free double cream into a bowl and whisk until it starts to thicken (a couple of minutes). In a separate bowl add your dairy free cream cheese, icing sugar and vanilla extract and whisk until combined (this should only take around a minute).
Add the thick double cream mixture to the cream cheese mixture, continuing to whisk until everything is combined (make sure not to over whisk as it can cause the dairy free ingredients to curdle).
Add your mini eggs to the filling (I like to crush them with a rolling pin before adding so they are smaller - save a few for decorating the top). Mix well and then spoon the filling onto the biscuit base and smooth the top with a knife. Decorate with more mini eggs and place in the fridge to set in the fridge (ideally leave overnight as the dairy free ingredients mean the cheesecake isn’t quite as firm as one containing dairy so needs slightly longer).
Serve cold and store in the fridge for up to 4 days.
