Description

This easy Blackberry Crisp recipe offers a delightful end to a summer meal with its juicy, jammy blackberry filling topped with a crunchy oat and brown sugar crumble. Toasted walnuts add a nutty depth, while refreshing lemon zest and vanilla brighten the flavors. Baked to golden perfection and served warm with a scoop of creamy vanilla ice cream, this dessert perfectly balances sweet, tart, and crisp textures for an irresistible treat.


Ingredients

Fruit Filling

  • 2 pints blackberries (24 ounces)
  • 1 tablespoon cane sugar
  • 1 tablespoon cornstarch
  • 1 teaspoon fresh lemon juice
  • 1 teaspoon lemon zest
  • 1 teaspoon vanilla extract

Topping

  • ¾ cup whole rolled oats
  • ¾ cup almond flour
  • ½ cup brown sugar
  • ½ cup crushed walnuts
  • ¾ teaspoon cinnamon
  • Heaping ¼ teaspoon sea salt
  • 6 tablespoons firm coconut oil

To Serve

  • Vanilla ice cream


Instructions

  1. Preheat and prepare dish: Preheat your oven to 400°F (205°C). Grease an 8x8-inch baking dish or a similar-sized dish to prevent sticking and ensure easy cleanup.
  2. Mix the filling: In a large bowl, combine the blackberries, cane sugar, cornstarch, fresh lemon juice, lemon zest, and vanilla extract. Toss everything gently until the blackberries are evenly coated with the mixture, which helps thicken the juices during baking.
  3. Prepare the topping: In a medium mixing bowl, combine the rolled oats, almond flour, brown sugar, crushed walnuts, cinnamon, and sea salt. Using your hands, work the firm coconut oil into the dry ingredients until the topping becomes crumbly and evenly coated, which creates a crunchy texture once baked.
  4. Assemble and bake: Transfer the blackberry filling to the prepared baking dish, spreading it evenly. Sprinkle the crumbly topping evenly over the berries. Bake in the preheated oven for 25 to 35 minutes, until the fruit filling is bubbling and the topping has turned a golden brown color.
  5. Cool and serve: Remove the crisp from the oven and let it cool for about 5 minutes to set slightly. Serve warm with generous scoops of vanilla ice cream for a classic finish.

Notes

  • You can substitute walnuts with pecans or almonds based on your preference or nut availability.
  • For a gluten-free version, ensure all ingredients, especially oats and almond flour, are certified gluten-free.
  • Firm coconut oil is best for the topping to achieve the right crumbly texture; avoid melted or liquid oils.
  • Leftovers can be refrigerated in an airtight container for up to 3 days and reheated before serving.
  • This crisp can also be made with other berries like blueberries, raspberries, or a mixed berry blend.
