Ingredients
- 1/2 cup white sugar: Adds sweetness to both the filling and the crumble.
- 1/4 cup brown sugar: Provides a hint of molasses flavor, enhancing the overall taste.
- 1 cup all-purpose flour: Acts as the base for the crumble and crust.
- 3/4 cup quick oats: Offers a chewy texture and heartiness to the bars.
- 1 egg yolk (room temperature): Binds the ingredients together and adds richness.
- 1/2 cup unsalted butter (melted): Gives the crumble a rich flavor and a buttery texture.
- 1/2 cup white sugar (for filling): Sweetens the blueberry mixture.
- 3 tbsp lemon juice: Balances the sweetness and enhances the berry flavor.
- 2 cups frozen blueberries (or fresh): The star ingredient, providing natural sweetness and fruity goodness.
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.
