  • Fresh Lemon Juice: Adds a tangy twist, helping to bring out the full flavor of the blueberries.
  • Cinnamon: Adds warmth and complexity to the crumble, complementing the fruitiness of the blueberries perfectly.

Vanilla Almond Granola topping

  • Old-Fashioned Oats: Provide a hearty and wholesome base for the granola topping.
  • Vanilla Almond Granola: Store-bought for convenience, adds a flavorful and crunchy element to the crumble.
  • Lightly Packed Brown Sugar: Adds sweetness and caramel notes to the topping.
  • Kosher Salt: Enhances flavors and balances the sweetness of the crumble.
  • Melted Butter (Unsalted): Binds the ingredients together and adds richness to the topping.
  • Cold Unsalted Butter: Cut into pieces to create a crumbly texture when mixed with other ingredients.

How to Make Blueberry Crumble?

Step One: Clean the Fresh Blueberries

Preheat the oven to 350 degrees Fahrenheit. Rinse and drain the blueberries and be sure to remove any stems from the blueberries. 

Step Two: Prepare the Blueberry Filling

Take a 9 by 9 inch or a 9 by 13 inch baking dish, mix together the blueberries, maple syrup, cornstarch, lemon zest, lemon juice and cinnamon.

Step three: Prepare the Crumble Topping

In a medium bowl, stir together the oats, vanilla almond granola, brown sugar and salt. Mix in the butter.

Step four: Assemble the Blueberry Crumble

Pour the oat mixture over the fruit filling and place the remaining 4 tablespoons of cold butter on top of the mixture.

Step five: Bake and Serve

Bake for 45 minutes or until bubbly, crisp and golden brown. Serve your Blueberry Crumble with vanilla ice cream.

Expert Tips

  • Blueberry Preparation: For a thick and luscious blueberry layer in the crumble, coat fresh or frozen blueberries in a corn flour mixture before adding to the filling.
  • Blueberry Options: Fresh blueberries are great, but frozen berries works too. Let frozen blueberries thaw to room temperature before using to avoid excess moisture in the dish.

Variations

  • Blueberry Crumble Bars: Transform the classic crumble into delectable blueberry crumble bars by baking a bit longer, then cut them into squares using a pastry cutter.
  • Almond Infusion: Enhance the almond flavor by incorporating sliced almonds into the crumble topping for a nutty crunch.
  • Blueberry Crumble Pie: Infuse the essence of a blueberry crisp into a comforting blueberry pie crust, marrying the best of both worlds in each delightful slice.

Substitutions

  • Granola Variation: Substitute vanilla almond granola with regular granola and a touch of vanilla extract for added flavor in the crumble topping.
  • Sugar Substitution: Brown sugar provides a rich caramel taste, but granulated or regular sugar can be used as alternatives in the crumble.
  • Oats Choices: While old-fashioned oats are recommended, rolled oats or quick oats can be suitable alternatives based on what you have available.

storage & reheating instructions

  • Storage: Store any leftover blueberry crumble or blueberry crumble bars in an airtight container in the refrigerator for up to 3-4 days.
  • Packaging Tip: For convenience and freshness, individually wrap each blueberry crumble bar in wax paper or food-grade paper before storing them in an airtight container.
  • Reheating (Optional): To reheat, place individual servings in an oven preheated to 350°F (175°C) for about 10-15 minutes or until warmed through. Alternatively, microwave individual portions for 30-60 seconds until heated to your liking. Enjoy!

What to Serve with this Recipe?

  • Vanilla Ice Cream: Serve warm blueberry crumble or blueberry crumble bars with a scoop of creamy vanilla ice cream for a delightful contrast of temperatures and flavors.
  • Whipped Cream: Top the crumble with a dollop of freshly whipped cream for added richness and a light, airy texture.
  • Fresh Berries: Garnish the dish with a few fresh blueberries or mixed berries to enhance the fruity flavors and add a pop of color.
