Blueberry Crumble Bars Recipe: A Delightful Treat

If you’re in search of a delicious and easy-to-make dessert that celebrates the delightful flavour of blueberries, look no further than blueberry crumble bars. These scrumptious treats combine a buttery, crumbly base with sweet and tangy blueberries, making them perfect for any occasion, whether it be a sunny afternoon tea or a cosy family dessert. Here’s a simple yet scrumptious recipe to bring these wonderful bars into your kitchen!

Ingredients

For the Base and Topping:

  • 200g plain flour
  • 100g rolled oats
  • 100g brown sugar
  • 100g unsalted butter, softened
  • 1/2 teaspoon baking powder
  • A pinch of salt

For the Blueberry Filling:

  • 300g fresh blueberries (or frozen, if unavailable)
  • 50g granulated sugar (adjust depending on the sweetness of your berries)
  • 1 tablespoon cornflour
  • Juice of half a lemon
  • 1 teaspoon vanilla extract

Method

  1. Prepare Your Oven: Preheat your oven to 180°C (160°C for fan ovens), and line a 9×9 inch (20×20 cm) baking tin with baking paper, allowing it to hang over the edges for easy removal later.

  2. Make the Base and Topping: In a large mixing bowl, combine the plain flour, rolled oats, brown sugar, baking powder, and a pinch of salt. Add the softened butter and use your fingers to rub it into the dry ingredients until you achieve a crumbly texture. You can also use a food processor for a quicker method.

  3. Set Aside: Take about two-thirds of the mixture and press it firmly into the bottom of the prepared baking tin to form an even layer. This will be your base. Reserve the remaining crumb mixture for the topping.

  4. Prepare the Blueberry Filling: In another bowl, toss the blueberries with the granulated sugar, cornflour, lemon juice, and vanilla extract until the blueberries are well coated. Spread this mixture evenly over the base in the baking tin.

  5. Add Topping: Sprinkle the reserved crumb mixture evenly over the blueberry layer, ensuring that the berries are mostly covered.

  6. Bake: Place the baking tin in the preheated oven and bake for 25–30 minutes, or until the topping is golden brown and the blueberries are bubbling.

  7. Cool and Serve: Once baked, remove the tin from the oven and allow it to cool in the tin for about 10 minutes. Carefully lift the bars out using the overhanging baking paper and let them cool completely on a wire rack. Once cool, slice into squares or bars.

  8. Enjoy: These blueberry crumble bars are delicious served warm or at room temperature. They can be enjoyed on their own or with a dollop of whipped cream or a scoop of ice cream for an indulgent treat.

Tips and Variations

  • Storage: Keep any leftovers in an airtight container at room temperature for up to three days or refrigerate for up to a week. They can also be frozen for up to three months.

  • Different Fruits: While blueberries are the star of this recipe, you can experiment with other berries like raspberries, strawberries, or even a mix of your favourites.

  • Additional Flavour: For added depth, consider adding a pinch of cinnamon to the crumble mix or some lemon zest to the blueberry filling.

Conclusion

Blueberry crumble bars are not only simple to prepare but also a delightful addition to any dessert spread. With their perfect balance of sweetness and tartness, these bars are destined to become a family favourite. So why not create a batch today and experience the joy of these wonderfully comforting treats? Enjoy baking!
