Ingredients
  

For the filling
  • 6 cups mixed berries (raspberries, blackberries, blueberries, and hulled/chopped strawberries)
  • 1/2 cup granulated sugar reduce to 1/3 cup if berries are very sweet
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch for thickening; arrowroot is a 1:1 substitute
  • 1/4 teaspoon ground cinnamon
For the crumble topping
  • 1 cup all-purpose flour use 1:1 gluten-free blend to make it GF
  • 1/2 cup packed brown sugar
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 cup cold unsalted butter, cut into small pieces use plant-based butter for vegan
  • 1/2 cup walnuts, chopped pecans or almonds work well

Method
 

Preparation
  1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or a large oven-safe skillet.
  2. In a large bowl, combine the mixed berries, granulated sugar, lemon juice, and cinnamon. Toss gently to mix.
  3. Sprinkle the cornstarch over the berries and toss again until the fruit is evenly coated. Transfer the mixture to your prepared dish, spreading it into an even layer.
  4. In a separate bowl, whisk together the flour, brown sugar, baking powder, and salt until evenly distributed.
  5. Add the chilled butter pieces to the dry mix. Using your fingers or a pastry cutter, rub the butter into the flour until you have large, pea-size crumbs.
  6. Stir in the chopped walnuts so they’re distributed through the topping.
  7. Scatter the crumble topping evenly over the berries, covering them completely.
Cooking
  1. Bake at 375°F for 30–35 minutes, or until the topping is golden brown and the filling is bubbly at the edges.
  2. Remove from the oven and let the crumble rest for about 5 minutes so the filling sets up slightly.
Serving
  1. Serve warm, optionally with a scoop of vanilla ice cream or a dollop of crème fraîche.

Notes

For extra crunch, fold in an additional 1/4 cup of oats or seeds into the topping. If your berries are very juicy, increase cornstarch to 3 tablespoons.
