Ingredients you’ll need
Here’s a list of ingredients you’ll need to make these bars. You can find my recipe card at the bottom of this post for the complete list with their amounts.
For the Crumble:
- Plain/all-purpose flour
- Baking powder
- Unsalted butter: Melted.
- Light brown sugar
- Vanilla extract
For the Blueberry Filling:
- Fresh blueberries
- Caster/granulated sugar
- Lemon juice
How to make Blueberry Crumble Bars
To make these bars, simply grab a medium mixing bowl and whisk together the flour, baking powder, and salt. Set aside.
In a separate large mixing bowl, whisk together the melted butter, sugar, and vanilla extract.
Add to the dry ingredients and mix in with a fork to form a crumbly mixture.
Press half of the mixture into the base of an 8×8-inch square baking pan lined with foil or parchment paper.
For the filling, add the blueberries to a medium mixing bowl. Mix in the sugar, cornflour, and lemon juice until the blueberries are fully coated.
Pour the blueberries over the base and spread out evenly.
Sprinkle the remaining crumble mixture on top of the blueberries, pressing it down gently.
Bake for 35 – 40 minutes until the top is golden brown. Allow to cool completely in the pan on wire rack before cutting into bars.
The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.
NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.
Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
These Blueberry Crumble Bars are:
- deliciously thick, soft, and buttery
- super quick and easy to make
- loaded with fresh, juicy blueberries
- the perfect dessert bars for summer time!
How long will these blueberry crumble bars last? These bars will stay fresh, stored in an airtight container, at room temperature or in the fridge for up to 1 week.
