A runny cheesecake texture is a common problem for no-bake cheesecakes and is less likely to occur for a recipe like this that includes eggs. My tip to avoiding the possibility of a runny cheesecake altogether is to cover the pan with foil. Since we’re pressure cooking this cheesecake, the foil protects the cheesecake from any steam inside the Instant Pot and stops the cheesecake from any water leakage. If you end up with a runny cheesecake, continue to bake it a little bit longer until the cheesecake is no longer runny.
