Ingredients 

Peach and Blueberry Filling

  • 6 large peaches peeled and sliced
  • ¾ c. fresh blueberries
  • ½ cup dark brown sugar
  • 1 ½ tablespoon all-purpose flour
  • 1 ½ tablespoon cornstarch
  • Pinch of salt
  • ½ teaspoon ground cinnamon
  • 2 teaspoons vanilla bean paste
  • 1 tablespoon lemon juice

Oat Topping

  • 1 cup all-purpose flour
  • 1 cup old-fashioned oats
  • ½ cup unsweetened coconut flakes
  • ¾ cup granulated sugar
  • ¾ teaspoon kosher salt
  • 1 teaspoon ground cinnamon
  • 8 tablespoons unsalted butter melted

For Serving (Optional)

  • Vanilla ice cream
  • Fresh whipped cream

Instructions

  • Preheat the oven to 375°F.
  • In a medium bowl, combine the flour, oats, granulated sugar, salt, cinnamon, and melted butter. Stir until large crumbs form. Place the crumble mixture in the refrigerator while preparing the filling.
  • Add the sliced peaches to a 9x13-inch baking dish, large casserole dish, or deep pie dish.
  • Sprinkle in the brown sugar, flour, cornstarch, salt, cinnamon, vanilla bean paste, and lemon juice. Toss gently until the peaches are evenly coated.
  • Sprinkle the chilled crumble topping evenly over the peaches.
  • Bake for 40–50 minutes, or until the topping is golden brown and the peach filling is bubbling around the edges.
  • Allow the crumble to cool for 10–15 minutes before serving.
  • Serve warm with vanilla ice cream or whipped cream, if desired.

Notes

  • The peaches do not need to be perfectly ripe, but avoid overly firm peaches for the best texture.
  • If your peaches are exceptionally juicy, add an extra teaspoon of cornstarch.
  • Chilling the crumble topping helps create larger crunchy clusters.
  • Orange juice can be substituted for lemon juice for a sweeter, softer citrus flavor.
