Notes

  • Storage: Keep in the refrigerator for up to 3-4 days.
  • Freezing: Can be frozen for up to 2 months if well wrapped.
  • For a dairy-free version, use coconut oil or plant-based butter for the crust and whipped coconut cream instead of whipped cream.
  • Make-ahead: This pie is best when chilled for a few hours before serving.
