Another great swap is using whole grain flour instead of all-purpose flour. Whole grain flour adds fiber and nutrients. Both swaps keep your dessert tasty and a bit healthier. Adding spices can take your crumble to the next level. Nutmeg brings a warm, cozy flavor. Just a pinch goes a long way. You can also incorporate nuts like walnuts or pecans for a delightful crunch.

Ingredients
  

  • 2 cups fresh blueberries
  • 1 tablespoon freshly grated lemon zest
  • 2 tablespoons freshly squeezed lemon juice
  • 1 4 cup granulated sugar
  • 1 tablespoon cornstarch
  • 1 teaspoon pure vanilla extract
  • 1 cup rolled oats
  • 1 2 cup all-purpose flour
  • 1 4 cup packed brown sugar
  • 1 2 teaspoon ground cinnamon
  • 1 4 teaspoon salt
  • 1 3 cup melted coconut oil or unsalted butter

Instructions
 

  • Begin by preheating your oven to 350°F (175°C). Lightly grease an 8-inch square baking dish or any similar-sized dish with cooking spray or a little extra melted oil.
  • In a large mixing bowl, combine the fresh blueberries, lemon zest, lemon juice, granulated sugar, cornstarch, and vanilla extract. Stir gently to ensure the blueberries are well-coated, then set aside the mixture to allow the juices to meld for about 10 minutes.
  • In a separate bowl, mix together the rolled oats, flour, brown sugar, cinnamon, and salt until thoroughly combined. Pour in the melted coconut oil (or butter) and mix with a fork or your hands until the mixture resembles a crumbly texture, with some larger clumps.
  • Carefully pour the blueberry mixture into the prepared baking dish, spreading it evenly across the bottom to create a base layer.
  • Evenly sprinkle the crumble mixture over the blueberries, ensuring every part of the blueberry layer is covered for a delicious topping.
  • Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the crumble topping turns golden brown and the blueberries begin to bubble invitingly around the edges.
  • After baking, remove the dish from the oven and allow it to cool for about 5-10 minutes before serving to let the flavors settle.
