Ingredients

Scale

Crumb Topping

  • 1 cup all purpose flour
  • ½ cup packed light brown sugar
  • ¼ cup granulated sugar
  • ¼ teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ¼ teaspoon salt
  • ½ cup butter, chilled and cut into small pieces
  • ¼ cup chopped walnuts

Raspberry Filling

  • 6 cups fresh raspberries
  • ¼ cup granulated sugar
  • 1 cup walnuts, chopped
  • 1 tablespoon lemon juice
  • 1 tablespoon lemon zest

Instructions

  1. Preheat and Prepare: Preheat your oven to 375°F (190°C). Spray a 2-quart or 9×9 inch baking dish with non-stick cooking spray and set it aside to get ready for the filling and topping.
  2. Mix Dry Ingredients for Crumb Topping: In a medium bowl, whisk together the all-purpose flour, light brown sugar, granulated sugar, ground cinnamon, ground nutmeg, and salt until well combined, forming the base of your crumble topping.
  3. Incorporate Butter: Cut the chilled butter into the flour mixture using a pastry cutter or your fingers until the mixture resembles coarse crumbs, ensuring a buttery texture for the crumble.
  4. Add Walnuts to Crumb: Stir in ¼ cup of chopped walnuts to the crumb mixture, adding a crunchy texture and nutty flavor to the topping.
  5. Prepare Raspberry Filling: In a large bowl, combine the fresh raspberries, ¼ cup granulated sugar, lemon juice, lemon zest, and 1 cup chopped walnuts. Stir gently to combine and let the mixture sit for 5 minutes to enhance the flavors.
  6. Assemble in Baking Dish: Pour the raspberry mixture into the prepared baking dish, spreading it evenly. Next, sprinkle the crumb topping evenly over the raspberry filling, covering it completely.
  7. Bake the Crumble: Place the dish in the preheated oven and bake uncovered for 30-35 minutes or until the topping is golden brown and the filling is bubbling slightly around the edges.
  8. Cool and Serve: Remove from the oven and let the crumble cool for 10-15 minutes to allow the filling to set before serving.
  9. Optional Serving Suggestion: Serve warm with a scoop of vanilla ice cream for an extra indulgent dessert experience.

Notes

  • Ensure butter is chilled for the crumb topping to achieve the right texture.
  • Allowing the raspberry filling to sit before baking helps to release natural juices and enhance flavor.
  • Walnuts add crunch; you can substitute with pecans if preferred.
  • Store leftovers covered in the refrigerator and consume within 3 days.
  • For a gluten-free version, substitute all-purpose flour with a gluten-free baking blend.
