How long can you keep unbaked cheesecake with biscuit base?

Unbaked cheesecake with a biscuit base can typically be stored in the refrigerator for about 3 to 5 days. It's best to keep it covered tightly to prevent it from absorbing any odors. If you need to store it longer, consider freezing it, which can extend its shelf life for up to 2 months. However, freezing may affect the texture, so it's recommended to thaw it in the refrigerator before serving.
