To Make the Crumble
- 150 g Rolled Oats
- 175 g Plain Flour
- 150 g Light Brown Sugar
- 150 g Unsalted Butter (cold and cubed)
For the Blueberry Filling
- 400 g Blueberries
- 175 g Blueberry Jam
- Juice of 1 Lemon
- 1 tbsp Cornflour
To Make the Crumble
Line a 9” square cake tin with non-stick baking paper. Preheat the oven to 180C (160C Fan).
Add the rolled oats, plain flour, light brown sugar and unsalted butter to a large bowl.
Rub the ingredients together with your fingers until the mixture resembles bread crumbs and there are no lumps of butter left.
To Make the Filling
Add the blueberries, jam, lemon juice and cornflour to a separate bowl.
Mash the ingredients together until they are combined. You still want there to be some texture to the blueberries.
Putting it All Together
Pour half of the crumble mixture into the base of your lined tin. Press down firmly until there are no gaps in the base.
Pour the blueberry mixture on top and spread over the crumble base.
Sprinkle over the remaining crumble mixture.
Bake in the oven for 30-35 minutes or until lovely and golden in colour.
Leave the bars to cool fully before portitoning.

- I used light brown sugar in this recipe. You can replace this with caster sugar if you prefer.
- These are blueberry crumble bars, but the blueberries can be replaced with any other berry you fancy.
- These Blueberry Crumble Bars can be quite soft. Once cooled you can refrigerate before portioning to make it easier.
