Ingredients

1/2 cup white sugar: Adds sweetness to balance the natural tartness of the blueberries.
1/4 cup brown sugar: Enhances the depth of flavor with its rich molasses notes.
1 cup all-purpose flour: Provides the structure for the crumble and the base of the bars.
3/4 cup quick oats: Adds texture and heartiness to the crust.
1 egg yolk (room temperature): Binds the ingredients together and enriches the flavor.
1/2 cup unsalted butter (melted): Creates a rich, buttery texture in the crust.
1/2 cup white sugar: A second addition for just the right sweetness in the filling.
3 tbsp lemon juice: Brightens the flavor of the blueberries and balances sweetness.
2 cups frozen blueberries (or fresh): The star of the dish, providing juicy bursts of flavor.

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.
In a large mixing bowl, combine the brown sugar, white sugar, all-purpose flour, and quick oats. Stir until well mixed.
Add the egg yolk and melted butter to the flour mixture. Mix until the dough is crumbly but holds together when pressed.
Press about two-thirds of the dough mixture firmly into the bottom of the prepared baking pan. Set aside the remaining dough for topping.
In another bowl, gently combine the blueberries, 1/2 cup of white sugar, and lemon juice. Spread this berry mixture evenly over the crust you just pressed down.
Sprinkle the reserved crumble mixture over the top of the blueberries evenly.
Bake in the preheated oven for 30 to 35 minutes, or until the top is golden brown.
Remove from the oven and let cool in the pan before slicing into bars.

Storage: Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
Freezing: Wrap individual bars tightly and freeze them for up to 3 months. Thaw at room temperature before enjoying.
Variations: Try swapping out blueberries for raspberries or cherries for a different fruity twist. You can also add chopped nuts for additional crunch.
