Method

1. Preheat the oven

• Heat oven to 180°C (160°C fan) / 350°F.

• Grease and line a 9×13 inch (23×33 cm) baking tin with parchment paper.

2. Make the base & crumble

• In a large bowl, mix together the flour, oats, light brown sugar, baking powder, and salt.

• Add the cold diced butter and rub in with fingertips until the mixture resembles coarse crumbs.

• Stir in the vanilla extract.

• Press about two-thirds of the mixture firmly into the bottom of the prepared tin to form an even base. Reserve the remaining one-third for the crumble topping.

3. Prepare the berry filling

• In a separate bowl, combine the blueberries, raspberries, strawberries, sugar, cornflour, lemon juice, and lemon zest.

• Toss gently until the berries are evenly coated.

4. Assemble the bars

• Spread the berry mixture evenly over the base.

• Sprinkle the reserved crumble mixture over the top.

5. Bake

• Bake for 40–45 minutes, or until the top is golden brown and the berry filling is bubbling.

6. Cool & serve

• Allow the bars to cool completely in the tin before slicing into squares or rectangles.

• Serve as they are, or warm with a scoop of vanilla ice cream or whipped cream.
