Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. In a large bowl, toss 4 cups mixed berries with 3/4 cup granulated sugar, 2 tablespoons cornstarch, and 1 tablespoon fresh lemon juice until the berries are evenly coated and glossy.
  2. Step 2: Spread the berry mixture evenly onto a greased 9x13-inch sheet pan.
  3. Step 3: In a separate bowl, combine 1 cup rolled oats, 3/4 cup all-purpose flour, 1/2 cup packed brown sugar, 1 teaspoon ground cinnamon, and 1/4 teaspoon salt.
  4. Step 4: Add 6 tablespoons cold, cubed unsalted butter to the oat mixture and use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs with pea-sized bits.
  5. Step 5: Sprinkle the oat topping evenly over the berries in the sheet pan.
  6. Step 6: Bake in the preheated oven for 35-40 minutes until the topping is golden brown and the berry filling is bubbling around the edges.
  7. Step 7: Remove from oven and let cool for 15 minutes before serving warm with vanilla ice cream or whipped cream if desired.
