1 tablespoon lemon juice

1 tablespoon butter
1 teaspoon lemon zest
(Or……. Like I did in the video, I used a tin of blueberry pie filling as I hadn’t much time and this can had been sitting around waiting to be used )
Crumb base and topping
3 1/4 cups/ 405 grams all purpose flour
3/4 cups/ 150 grams sugar
1/4 cup /50 grams brown sugar
1/2 teaspoon baking powder
1 teaspoon corn flour
1/2 teaspoon salt
1 cup/ 227 grams cold butter- in cubes
1 egg
1/2 teaspoon vanilla
Instructions
Preheat oven to 175c/ 350F. Line a 9x13 inch baking tray with parchment paper.
In a small saucepan, combine 3 cups of blueberries, sugar, cornflour, salt and lemon juice. Stir on a low heat.
Bring it to a boil. Stir continuously for one minute then remove it from the heat.
Add the remaining 2 cups blueberries, butter and vanilla. Stir until the butter is melted. Cool the mixture.
Prepare the crust: Combine the flour, sugars, baking powder, corn flour and salt in a food processor. Pulse a couple times. Add the cold butter and pulse until the mixture resembles bread crumbs. Add the egg and vanilla. Pulse until the mixture resembles wet sand.
Pour half of the crust mixture into the prepared baking tray and press down into a crust form.
Bake in the oven for 10 minutes. Remove the crust from the oven and pour the blueberry filling over the crust.
Sprinkle the rest of the crust mixture over the blueberry filling. Do not pack it down.
Bake in the oven for another 50 minutes until golden brown.
Cool 2-3 hours before slicing and serving. As tempting as it is, if you cut it up before cooling, the bars will break apart.
