Ingredients

Scale
  • 5 large ripe peaches, peeled and sliced (about 4 cups)
  • 1/4 cup granulated sugar (adjust based on peach sweetness)
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon vanilla extract (optional)
  • 2 tablespoons cornstarch
  • 1/2 teaspoon ground cinnamon
  • 3/4 cup old-fashioned rolled oats
  • 1/2 cup all-purpose flour (can swap for almond flour for gluten-free)
  • 1/2 cup packed brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 6 tablespoons unsalted butter, melted (use dairy-free butter if needed)

Instructions

  1. Preheat oven to 350°F (175°C). Peel and slice peaches into 1/2-inch thick slices.
  2. In a bowl, toss peaches with granulated sugar, lemon juice, vanilla extract, cornstarch, and ground cinnamon until evenly coated and glossy. Add a splash of water if mixture is too dry.
  3. Pour peach mixture into a 9×9-inch baking dish, spreading evenly in a single layer. Drain excess liquid if needed.
  4. In a separate bowl, combine rolled oats, flour, brown sugar, ground cinnamon, and salt. Stir to mix dry ingredients evenly.
  5. Pour melted butter over oat mixture and toss with fingers or fork until coarse clumps form, crumbly but holding together when pressed.
  6. Sprinkle streusel topping evenly over peach filling.
  7. Bake for 35–40 minutes until topping is golden brown and peach juices bubble around edges. Cover loosely with foil if topping browns too quickly.
  8. Let cool for at least 10 minutes before serving. Serve warm, optionally with vanilla ice cream or whipped cream.

Notes

Use firm, ripe peaches for best texture. Frozen peaches can be used if thawed and drained well. Adjust sugar based on peach sweetness. Melted butter creates a crumbly streusel; cold butter yields chunkier topping. Cover with foil if topping browns too fast. Let crisp cool before serving to set filling. Reheat in oven to maintain crisp topping; avoid microwave.
