Some of the common reasons no bake cheesecakes don’t set include: using the wrong kind of cream, not whipping the cream enough, not chilling the cake long enough, or ratios are just off. Happily, there are easy fixes.  – Try to freeze the cheesecake instead of chilling it in the fridge. Take it out after a few hours and see if you can get a clean slice. – Instead of serving the cheesecake sliced on a plate, serve it in bowls. It will still be delicious.
