Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). In a medium bowl, combine 2 cups halved strawberries, 1 cup blueberries, 1 cup blackberries, 2 tbsp granulated sugar, and 1 tsp lemon zest. Toss gently until berries are coated and sugar dissolves.
  2. Step 2: Spread the berry mixture evenly in a 9x9-inch baking dish. In a separate bowl, mix 1/2 cup rolled oats, 1/4 cup all-purpose flour, 1/4 cup chopped walnuts, 2 tbsp cold cubed butter, and 1/4 cup brown sugar until crumbly and resembling coarse sand.
  3. Step 3: Sprinkle the crumble topping evenly over the berries. Bake for 35-40 minutes, or until the topping is golden brown and the berries are bubbling around the edges, stirring gently if needed to prevent burning.
