Ingredients
- 1 and 1/2 cups all-purpose flour: The base of the crust, providing structure and texture.
- 1 cup old-fashioned whole rolled oats: These add heartiness and a chewy texture to the bars.
- 1/2 cup packed light or dark brown sugar: Offers a rich, caramel-like sweetness that enhances the flavor.
- 1 teaspoon baking powder: Helps the bars rise slightly, creating a light texture.
- 1 teaspoon lemon zest: Brightens the flavors and adds a refreshing citrus twist.
- 1/4 teaspoon ground cinnamon: Provides warmth and depth to the filling.
- 1/8 teaspoon salt: Balances the sweetness and enhances the other flavors.
- 10 Tablespoons unsalted butter, melted: Binds the crust ingredients together while adding a rich flavor.
- 4 and 1/2 cups blueberries: The star of the recipe, bursting with sweet and tangy flavor.
- 1/2 cup granulated sugar: Sweetens the blueberry filling, balancing the tartness.
- 2 Tablespoons cornstarch: Thickens the filling for a perfect texture.
- 1 Tablespoon lemon juice: Adds acidity and depth to the blueberry flavor.
- 2 teaspoons lemon zest: Enhances the overall citrus notes in the filling.
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and line a 9-inch square pan with parchment paper for easy removal later.
- In a large bowl, whisk together the all-purpose flour, rolled oats, brown sugar, baking powder, lemon zest, cinnamon, and salt until well combined.
- Pour the melted butter into the dry ingredients and mix until crumbly, resembling coarse crumbs.
- Press about 2/3 of the mixture into the bottom of the prepared pan to form the crust. Bake for 10 minutes until lightly golden.
- While the crust is baking, combine the blueberries, granulated sugar, cornstarch, and lemon juice in a saucepan over medium heat. Stir gently until the mixture thickens, about 5-7 minutes.
- Pour the blueberry filling over the warm par-baked crust, spreading it evenly.
- Sprinkle the remaining crumbly mixture over the blueberry filling to create a topping.
- Return the pan to the oven and bake for an additional 45-55 minutes, or until the filling is set and the top is golden brown.
- Allow the bars to cool completely in the pan before cutting them into squares.
