Banana cream pie past the expiration date
Unopened
Follow the package date. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 3–4 days in the fridge from the day you open it.
How to keep banana cream pie fresh longer
- Keep at room temperature in a bread box or sealed bag for the best texture.
- Refrigeration slows mould but makes bread stale faster.
- Freeze what you will not eat in time.
