Equipment

  • 9x13-inch baking dish
  • mixing bowls
  • spatula or spoon
  • measuring cups and spoons
  • oven

Ingredients

  • 3 cups fresh strawberries, hulled and quartered
  • 2 cups fresh blueberries
  • 1 1/2 cups fresh raspberries
  • 1/3 cup granulated sugar
  • 2 tbsp light brown sugar
  • 3 tbsp cornstarch
  • 1 tbsp fresh lemon juice
  • 1 tsp lemon zest
  • 1 tsp pure vanilla extract
  • pinch of salt
  • 1 1/2 cups old-fashioned rolled oats
  • 3/4 cup all-purpose flour
  • 2/3 cup light brown sugar, packed
  • 1/2 tsp cinnamon
  • 1/4 tsp nutmeg
  • 1/4 tsp salt
  • 3/4 cup unsalted butter, cold and cubed
  • vanilla ice cream or whipped cream (for serving)

Instructions

  • Preheat oven to 350°F and lightly butter a 9x13-inch baking dish.
  • Combine strawberries, blueberries, raspberries, granulated sugar, brown sugar, cornstarch, lemon juice, lemon zest, vanilla extract, and salt in a large bowl.
  • Toss gently until evenly coated, then transfer to the prepared baking dish.
  • In another bowl, combine oats, flour, brown sugar, cinnamon, nutmeg, and salt.
  • Add cold butter and work it into the mixture using your fingers until crumbly with uneven clumps.
  • Spread the oat topping evenly over the berry filling without pressing too firmly.
  • Bake for 45 to 50 minutes until topping is golden and filling is bubbling throughout.
  • Remove from oven and let cool uncovered for at least 20 minutes.
  • Serve warm with vanilla ice cream or whipped cream.

Notes

Use cold butter for the topping to achieve a crisp texture. Do not reduce the cornstarch or the filling may become watery. Bake until the center is bubbling, not just the edges. Let cool uncovered to maintain a crunchy topping. Serve warm with vanilla ice cream for best results.
