Ingredients

1/2 cup white sugar: Adds sweetness to the blueberry filling.
1/4 cup brown sugar: Provides a deeper, richer flavor to the crumble topping.
1 cup all-purpose flour: Acts as the base for both the crumble and the bar crust.
3/4 cup quick oats: Adds texture and helps create a heartier crumble.
1 egg yolk (room temperature): Helps bind the ingredients together.
1/2 cup unsalted butter (melted): Adds richness and moisture to the bars.
3 tbsp lemon juice: Brightens the flavor of the blueberries and balances the sweetness.
2 cups frozen blueberries (or fresh): The star ingredient that brings the fruity flavor.

Step-by-Step Instructions

Preheat the oven to 350°F (175°C) and prepare an 8×8-inch baking pan by lining it with parchment paper.
In a large mixing bowl, combine brown sugar, white sugar, all-purpose flour, and quick oats. Stir until well incorporated.
Add the room temperature egg yolk and the melted unsalted butter to the dry mixture. Mix gently until the mixture becomes crumbly.
Set aside 1 cup of the crumble mixture for topping. Press the remaining mixture evenly into the bottom of the prepared baking pan.
In a separate bowl, combine the blueberries, white sugar, and lemon juice. Gently stir to coat the blueberries.
Spoon the blueberry mixture over the pressed base, spreading it evenly.
Sprinkle the reserved crumble mixture over the blueberry filling.
Bake for 30-35 minutes or until the topping is golden brown and the filling is bubbling.
Allow the bars to cool in the pan on a wire rack, then lift them out using the parchment paper and cut into squares.
