Ingredients

1/2 cup white sugar: Adds sweetness to the crumble base and blueberry filling.
1/4 cup brown sugar: Provides a hint of molasses flavor, enhancing the overall taste.
1 cup all-purpose flour: Forms the backbone of the crumble, giving structure and texture.
3/4 cup quick oats: Adds chewiness and a wholesome touch to the crumble topping.
1 egg yolk (room temperature): Helps bind the ingredients together, creating a tender texture.
1/2 cup unsalted butter (melted): Contributes richness and moisture to the crumble mixture.
3 tbsp lemon juice: Brightens the flavor of the blueberries, balancing their natural sweetness.
2 cups frozen blueberries (or fresh): The star ingredient, delivering a burst of flavor and color.

Step-by-Step Instructions

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare an 8×8-inch baking pan by lining it with parchment paper for easy removal later.
Mix the Crumble Base: In a large mixing bowl, combine the brown sugar, white sugar, all-purpose flour, and quick oats. Stir until well incorporated.
Incorporate Wet Ingredients: Add the egg yolk and melted unsalted butter to the dry mixture. Mix gently until the mixture becomes crumbly.
Press into the Pan: Reserve 1 cup of the crumble mixture for topping. Press the remaining mixture evenly into the bottom of the prepared baking pan to form the base.
Prepare the Blueberry Filling: In a separate bowl, combine the frozen blueberries (or fresh if using), white sugar, and lemon juice. Gently stir to evenly coat the blueberries.
Assemble the Bars: Spoon the blueberry mixture over the pressed base in the baking pan, spreading it evenly.
Add Topping: Sprinkle the reserved crumble mixture over the blueberry filling, ensuring an even coverage.
Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until the topping turns golden brown and the filling is bubbling.
Cool and Serve: Once baked, let the bars cool in the pan on a wire rack. Once cool, lift them from the pan using the parchment paper and cut into squares.
