Blueberry Crumble Bars

Ingredients

  • 1/2 cup white sugar: This sweetener helps balance the tartness of the blueberries, adding a lovely sweetness to the crumble and filling.
  • 1/4 cup brown sugar: Its molasses content contributes depth and a hint of caramel flavor to the crumble topping.
  • 1 cup all-purpose flour: This is the main structure for the crumble and provides the base for the bars.
  • 3/4 cup quick oats: Adding nutrition and chewiness, oats give the crumble its signature texture.
  • 1 egg yolk (room temperature): This helps bind the ingredients together and adds richness to the bars.
  • 1/2 cup unsalted butter (melted): The melted butter brings richness and moisture, ensuring a tender crumb.
  • 3 tbsp lemon juice: Brightens the flavor of the blueberries and helps enhance their natural sweetness.
  • 2 cups frozen blueberries (or fresh): These juicy berries are the star of the recipe, providing flavor and color.

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 bowl, combine the brown sugar, white sugar, flour, and quick oats. Mix until well blended.

  3. Add the egg yolk and melted butter to the dry ingredients, mixing until the mixture becomes crumbly.

  4. Reserve 1 cup of the crumble mixture, then press the remaining crumble evenly into the bottom of the prepared baking pan.

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

  6. Spoon the blueberry mixture evenly over the crumble base.

  7. Sprinkle the reserved crumble mixture on top of the blueberry filling.

  8. Bake for 30-35 minutes, or until the crumble is golden brown and the filling is bubbly.

  9. Allow the bars to cool before lifting them out of the pan using the parchment paper. Cut into squares for serving.
