Berry Crumble Squares

Difficulty: Easy–Medium • Makes: 12 squares
These berry crumble squares are half traybake, half dessert. With a buttery base, jammy fruit centre, and crumbly topping, they’re perfect for afternoon tea or as a lunchbox treat.
Ingredients
For the base and crumble:
- 250 g plain flour
- 200 g cold unsalted butter, cubed
- 100 g caster sugar
- ½ tsp salt
For the filling:
- 300 g mixed berries (fresh or frozen)
- 50 g sugar
- 1 tbsp cornflour
- 1 tsp lemon juice
Method
- Preheat the oven to 180°C (fan 160°C). Line a 20 x 20 cm baking tin with parchment.
- Make the base/crumble: In a bowl, rub the cold butter into the flour, sugar and salt until it looks like coarse crumbs and starts to clump together.
- Press about two-thirds of the mixture firmly into the base of the tin to form an even layer.
- In another bowl, toss the berries with sugar, cornflour and lemon juice.
- Spread the berries over the base.
- Scatter the remaining crumble mixture over the top.
- Bake for 30–35 minutes, until the top is lightly golden and the filling is bubbling at the edges.
- Allow to cool completely in the tin before slicing into squares.
