Ingredients

1/2 cup white sugar: This adds sweetness to balance the tartness of the blueberries.
1/4 cup brown sugar: Provides a rich depth of flavor and moisture.
1 cup all-purpose flour: The base of our crumble mixture, contributing to its beautiful texture.
3/4 cup quick oats: Adds heartiness and chewiness to the bars.
1 egg yolk (room temperature): Binds the ingredients together for a nice crumble.
1/2 cup unsalted butter (melted): Ensures a rich flavor and contributes to the buttery crumble.
3 tbsp lemon juice: Enhances the flavor of blueberries and adds a fresh brightness.
2 cups frozen blueberries (or fresh): The star ingredient, bursting with flavor and nutrients.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper for easy removal later.
In a large mixing bowl, combine the brown sugar, white sugar, all-purpose flour, and quick oats. Stir until well mixed to ensure even distribution of ingredients.
Add the egg yolk and melted butter to the dry mixture, and mix gently until crumbly. This will create the perfect texture for your crumble.
Reserve 1 cup of this crumble mixture for the topping, then press the remaining mixture evenly into the bottom of the prepared baking pan to form a solid base.
In a separate bowl, add the blueberries, white sugar, and lemon juice. Gently mix to coat the blueberries. This mixture will be the fruity filling for your bars.
Spoon the blueberry mixture over the pressed base and spread it evenly to cover the surface.
Sprinkle the reserved crumble mixture generously over the blueberry filling, ensuring even coverage to create a beautiful top.
Bake in the preheated oven for 30-35 minutes or until the topping is golden brown and the filling is bubbling, creating an inviting appearance.
Once baked, let the bars cool in the pan on a wire rack. After cooling, lift them out using the parchment paper and cut into squares.
