Chefs Notes

  • For extra richness, use melted butter instead of pieces and drizzle evenly.
  • Add a sprinkle of cinnamon or nutmeg for a warm spiced twist.
  • Serve with vanilla ice cream or whipped topping for a classic pairing.
  • If using fresh peaches, lightly sweeten them and add a bit of extra liquid.
