Fridge: Can be stored for up to 5 days.
Freezer: Can be frozen for up to 3 months, though it is best frozen without the whipped cream. You can still store it completely made, but once the cream is defrosted, the texture does change slightly. Still delicious though!
OTHER BERRY FILLINGS
Since berries are the lowest carb fruit available, you can also make this a blueberry or strawberry pie, or even a mixed berry pie. Many types of berries are available frozen.
