Notes

Storage Tips
  • Store leftovers in the refrigerator, covered, for up to 4 days. The texture will soften slightly as it sits, though the flavor remains rich and balanced.
  • To reheat, warm individual portions in the microwave or place the baking dish back in the oven at a low temperature until heated through.
  • This dessert can be assembled ahead of time and baked just before serving, making it ideal for gatherings or holidays.
  • Freezing is possible, though the topping may lose some of its crisp texture after thawing.
  • For serving, add a scoop of vanilla ice cream or a spoonful of whipped cream to contrast the warm filling.
