Ingredients
- 1 and 1/2 cups all-purpose flour: This forms the base of your crust, providing structure and richness.
- 1 cup old-fashioned whole rolled oats: Adds a lovely texture and a wholesome flavor to the crust.
- 1/2 cup packed light or dark brown sugar: Gives a depth of sweetness and a hint of caramel flavor.
- 1 teaspoon baking powder: Helps the crust rise slightly and stay tender.
- 1 teaspoon lemon zest: Brightens the flavors with its fresh, citrusy aroma.
- 1/4 teaspoon ground cinnamon: Adds warmth and a cozy touch to the overall flavor.
- 1/8 teaspoon salt: Enhances all the ingredients by balancing sweetness.
- 10 Tablespoons unsalted butter, melted: Provides richness and helps to bind the crust mixture.
- 4 and 1/2 cups blueberries: The star of the show, offering juiciness and vibrant flavor.
- 1/2 cup granulated sugar: Sweetens the blueberry filling to perfection.
- 2 Tablespoons cornstarch: Acts as a thickening agent for the blueberry filling.
- 1 Tablespoon lemon juice: Adds acidity and brightness to the blueberry mixture.
- 2 teaspoons lemon zest: Reinforces that lovely citrus note 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.
- In a large bowl, whisk together the flour, oats, brown sugar, baking powder, lemon zest, cinnamon, and salt until well combined.
- Pour the melted butter into the dry mixture and mix until it becomes crumbly.
- Press about 2/3 of the crumbly mixture evenly into the bottom of the prepared pan to form the crust.
- Bake the crust in the preheated oven for 10 minutes.
- Meanwhile, in a medium saucepan, combine the blueberries, granulated sugar, cornstarch, and lemon juice over medium heat. Stir gently until the mixture thickens, about 5-7 minutes.
- Pour the blueberry filling over the par-baked crust, spreading it evenly.
- Sprinkle the remaining crumbly mixture on top of the blueberries for added texture.
- Bake for an additional 45-55 minutes, or until the bars are set and lightly golden.
- Remove from the oven and allow to cool completely in the pan before cutting into squares.
