Ingredients

Scale
  • 56 ripe peaches, peeled and sliced (about 4 cups)
  • 1/4 cup brown sugar, packed (preferably dark brown sugar)
  • 2 tablespoons bourbon
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon ground cinnamon (optional)
  • 1 tablespoon cornstarch
  • 1 cup old-fashioned rolled oats
  • 3/4 cup all-purpose flour (can substitute almond flour for gluten-free)
  • 1/2 cup brown sugar, packed
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, cold and cubed

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9-inch baking dish lightly with butter or nonstick spray.
  2. In a large bowl, combine sliced peaches with brown sugar, bourbon, lemon juice, vanilla extract, cinnamon, and cornstarch. Toss gently until peaches are evenly coated.
  3. Transfer the peach mixture into the greased baking dish, spreading it out evenly.
  4. In a separate bowl, mix oats, flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter and cut it into the dry ingredients using a pastry cutter or forks until the mixture resembles coarse crumbs with pea-sized pieces.
  5. Sprinkle the oat streusel topping evenly over the peach filling, covering the fruit completely.
  6. Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the peach filling is bubbling around the edges.
  7. Let the crisp rest for at least 10 minutes before serving to allow the juices to thicken further. Serve warm, ideally with vanilla ice cream or whipped cream.

Notes

Use ripe but firm peaches to hold shape during baking. Keep butter cold for crumbly streusel topping. Don’t overmix streusel to avoid dense topping. Fresh lemon juice brightens the filling. For dairy-free, substitute butter with coconut oil or plant-based butter. For gluten-free, swap all-purpose flour with almond or oat flour. Adding chopped pecans or walnuts to streusel adds crunch. Reheat leftovers in oven to maintain crisp topping.
