Not all cheesecakes need to be baked, but in order to get the perfect texture, you’ll need to put your no-bake cheesecake in the freezer for at least three hours – but preferably overnight! If you skip this crucial step or cut short on the time needed, your cheesecake will be more like a cheesecake pudding mix. If you've already followed this crucial step in the past and are still looking to thicken up your no-bake cheesecakes, you can also add a touch of gelatin when preparing the filling.
