Instructions
Preparation Steps
Preheat oven to 375°F. Lightly grease an 8x8-inch baking dish.
Make the filling: In a large bowl, toss berries with 0.5 cup sugar, lemon juice, lemon zest, vanilla, and cornstarch until evenly coated. Spread the mixture into the prepared dish.
Make the topping: In a separate bowl, combine oats, flour, brown sugar, granulated sugar (if using), cinnamon, and salt.
Cut in the cold butter with a pastry cutter or fingertips until the mixture forms moist crumbs with some pea-sized pieces. Stir in pecans if using.
Scatter the topping evenly over the berry mixture, covering it completely.
Bake for 40 to 45 minutes, until the berries are bubbling in the center and the topping is golden brown.
Cool for 10 to 15 minutes before serving. Serve warm, plain or with vanilla ice cream.
Notes
Use a mix of blueberries, raspberries, blackberries, and strawberries. If using frozen berries, bake a few extra minutes until the filling bubbles in the center. Adjust sugar to taste based on berry sweetness.
