Blueberry Crumble Bars

Ingredients

  • 1/2 cup white sugar: Adds sweetness to the crumble and enhances the blueberries’ flavor.
  • 1/4 cup brown sugar: Provides a rich, caramel-like flavor and helps create a moist texture.
  • 1 cup all-purpose flour: Forms the base of the crumble and provides structure.
  • 3/4 cup quick oats: Offers a hearty texture and a lovely chewiness.
  • 1 egg yolk (room temperature): Acts as a binding agent for the crumble, enriching the overall flavor.
  • 1/2 cup unsalted butter (melted): Brings richness and moisture, contributing to the crumbly texture.
  • 3 tbsp lemon juice: Brightens the flavor of the blueberries and balances sweetness.
  • 2 cups frozen blueberries (or fresh): The star of the recipe, providing a burst of juicy flavor.

Step-by-Step Instructions

  1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper for easy removal.

  2. In a large mixing bowl, combine the brown sugar, white sugar, all-purpose flour, and quick oats. Stir until everything is well combined.

  3. Add the egg yolk and melted unsalted butter to the dry ingredients. Mix gently until the mixture is crumbly.

  4. Reserve 1 cup of the crumble mixture for later use. Press the remaining mixture evenly into the bottom of the prepared baking pan to create the base layer.

  5. In a separate bowl, combine the frozen blueberries with white sugar and lemon juice. Mix gently to coat the blueberries.

  6. Spoon the blueberry mixture over the pressed base and spread it evenly across the surface.

  7. Sprinkle the reserved crumble mixture over the blueberry filling to create a topping.

  8. Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the filling is bubbling.

  9. Allow the bars to cool in the pan on a wire rack. Once cooled, lift them out using the parchment paper and cut into squares.
