Ingredients
Scale
Crust and Crumbles:
- 140 grams (1 cup) all-purpose flour
- 144 grams (1 and 1/2 cups) rolled oats
- 140 grams (2/3 cup) granulated sugar
- 150 grams (2/3 cup) unsalted butter, melted and cooled
Blueberry Filling:
- 300 grams (2 cups) blueberries
- 50 grams (1/4 cup) granulated sugar
- 2 teaspoons cornstarch
- 1 tablespoon lemon juice
- 1 and 1/2 teaspoons lemon zest (zest of 1 large lemon)
Instructions
- Preheat your oven to 350°F (177°C). Grease an 8-inch (20cm) square baking dish and line with parchment paper, leaving an overhang for easy removal.
- In a medium bowl, mix flour, rolled oats, and sugar. Stir in melted butter until combined.
- Reserve 1/3 of the mixture (approximately 190 grams) for the crumble topping. Press the remaining mixture evenly into the prepared baking dish to form the crust.
- In another bowl, toss blueberries with sugar, cornstarch, lemon juice, and lemon zest until coated. Spread this mixture over the crust.
- Sprinkle the reserved crumble mixture over the blueberries, pressing lightly to adhere.
- Bake for 38-40 minutes until the top is golden brown and the filling is bubbling.
- Cool completely in the dish before slicing into bars.
