Why Use an Air Fryer?

Air fryers have become popular kitchen appliances due to their ability to cook food quickly with less oil. This not only makes them healthier but also more convenient. Using an air fryer for baking can provide a quicker cooking time with less energy consumption compared to a traditional oven. Plus, it adds crispness to the crumble that everyone loves.

Ingredients You'll Need

  • 200g plain flour
  • 100g granulated sugar
  • 120g unsalted butter, chilled and cubed
  • 1 tsp vanilla extract
  • Pinch of salt
  • 300g fresh blackberries
  • 50g rolled oats
  • 30g light brown sugar
  • Zest of 1 lemon
  • 1 tbsp cornstarch

Step-by-Step Instructions

Step 1: Make the Crumble Base

Start by making the crumble base. In a mixing bowl, combine the flour, granulated sugar, and a pinch of salt. Add in the chilled, cubed butter and vanilla extract. Use your fingers or a pastry cutter to blend the ingredients until it resembles coarse crumbs.

Step 2: Assemble the Crumble Bars

Reserve about 1 cup of the crumble mixture for the topping. Press the remaining mixture firmly into the bottom of a greased and lined air fryer-friendly baking pan. Ensure it's compact to help it hold together after baking.

Step 3: Prepare the Blackberry Filling

In a separate bowl, combine the fresh blackberries, light brown sugar, lemon zest, and cornstarch. The cornstarch will help thicken the berry juices during cooking, creating a luscious filling. Spread this berry mixture evenly over the crumble base.

Step 4: Add the Crumble Topping

Mix the reserved crumble mixture with rolled oats to add texture, and spread it evenly over the blackberry layer. This will bake into a golden, crisp top.

Step 5: Air Frying Time

Set your air fryer to 160°C (320°F) and preheat for about 5 minutes. Carefully place the baking pan inside the air fryer basket. Air fry for 20-25 minutes or until the top is golden brown and the blackberry filling is bubbly. Remember to check occasionally to prevent over-browning.

Tips for Success

  • Quality Ingredients: Use fresh, ripe blackberries for the best flavor.
  • Chilled Butter: Ensure your butter is cold right up to the moment you use it to get that perfect crumbly texture.
  • Don’t Overcrowd: If your air fryer is small, consider cooking in batches to ensure even cooking.
  • Alternative Fruits: Feel free to experiment with other berries like raspberries or strawberries.

Serving Suggestions

Allow the crumble bars to cool slightly before cutting into squares. They are wonderful served warm or at room temperature, and a scoop of vanilla ice cream or a dollop of whipped cream can make them extra special.

Storage Instructions

Store any leftover bars in an airtight container in the fridge for up to 3 days. You can also freeze them for longer storage. Simply wrap each bar individually in cling film and freeze. To reheat, place in the air fryer for a few minutes to restore the crispness.

Conclusion

These easy-to-make blackberry crumble bars are a perfect treat for any occasion. With the help of your trusty air fryer, they're quick to make, and your kitchen won't get overheated. Their combination of tangy berries, sweet crumble, and the crunchy topping makes a delightful dessert that everyone will enjoy. Happy cooking!
