Ingredients Equipment Method Notes

Ingredients
  

  • 4 cups fresh peaches, sliced
  • 2 cups fresh blueberries
  • 1/3 cup granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp lemon juice
  • 1 tsp vanilla extract
  • 1 cup old-fashioned oats
  • 3/4 cup all-purpose flour
  • 1/2 cup brown sugar
  • 1/2 tsp cinnamon
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, melted

Equipment

  • mixing bowls
  • baking dish
  • measuring cups and spoons
  • spoon or spatula
  • oven

Method
 

  1. Preheat your oven to 350°F and lightly grease a baking dish.
  2. In a large bowl, mix peaches, blueberries, sugar, cornstarch, lemon juice, and vanilla until evenly coated.
  3. Pour the fruit mixture into the prepared baking dish and spread it out evenly.
  4. In another bowl, combine oats, flour, brown sugar, cinnamon, and salt.
  5. Stir in melted butter until the mixture becomes crumbly.
  6. Sprinkle the topping evenly over the fruit layer.
  7. Bake for 35–40 minutes, until the top is golden and the filling is bubbling.
  8. Let cool slightly before serving.

Notes

Use ripe but firm peaches for best texture. Toss fruit gently to avoid crushing blueberries. Let the crisp rest before serving to thicken properly. Add a pinch of nutmeg for extra warmth. Bake on a sheet pan to catch bubbling juices. You can swap peaches for nectarines, use frozen fruit (increase bake time), or make it gluten-free with a 1:1 flour substitute.
