Blueberry Crumble Bars

Ingredients

  • 1/2 cup white sugar: Sweetens the filling and helps balance the tartness of the blueberries.
  • 1/4 cup brown sugar: Adds a rich, caramel-like flavor to the crumble.
  • 1 cup all-purpose flour: Forms the base of the crumble and adds structure.
  • 3/4 cup quick oats: Introduces a hearty texture and wholesome flavor.
  • 1 egg yolk (room temperature): Acts as a binding agent to help the crumble hold together.
  • 1/2 cup unsalted butter (melted): Provides richness and moisture to the dough.
  • 1/2 cup white sugar (for filling): Further sweetens the blueberry mixture for balance.
  • 3 tbsp lemon juice: Brightens the flavor of the filling and complements the blueberries.
  • 2 cups frozen blueberries (or fresh): The star ingredient that brings vibrant flavor and color to the bars.

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 well mixed.
  3. Add the egg yolk and melted butter to the flour mixture. Mix until the dough is crumbly but holds together when pressed.
  4. Press about two-thirds of the dough mixture firmly into the bottom of the prepared baking pan. Set aside the remaining dough for topping.
  5. 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.
  6. Sprinkle the reserved crumble mixture over the top of the blueberries evenly.
  7. Bake in the preheated oven for 30 to 35 minutes, or until the top is golden brown.
  8. Remove from the oven and let cool in the pan before slicing into bars.
