Ingredients:
- 2 cups (250g) all-purpose flour
- ½ cup (100g) granulated sugar
- ¾ cup (170g) unsalted butter, melted
- ¼ tsp (1.5g) salt
- 3 cups (450g) fresh blackberries
- ⅓ cup (65g) granulated sugar
- 2 tbsp (30ml) lemon juice
- 2 tbsp (16g) cornstarch
Instructions:
- Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
- In a large bowl, stir together the flour, 100g sugar, and salt. Pour in the melted butter and mix until a soft dough forms.
- Press two-thirds of the dough mixture firmly into the bottom of the prepared pan using the back of a spoon.
- Place the blackberries, 65g sugar, and lemon juice in a saucepan over medium heat. Cook for 5–7 minutes, lightly smashing some berries with a spatula to release their juices.
- Whisk the cornstarch with a teaspoon of water to create a slurry, stir it into the berry mixture, and simmer for 1 minute until the filling thickens and looks glossy.
- Spread the thickened blackberry filling evenly over the pressed crust.
- Crumble the remaining one-third of the dough over the top with your fingers, leaving small gaps for the filling to bubble through.
- Bake for 40–45 minutes until the edges are golden brown and the filling is bubbling.
