Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1/2 cup granulated sugar
  • 2 cups all-purpose flour
  • 1/4 teaspoon salt
  • 2 cups fresh blueberries
  • 1 tablespoon lemon zest
  • 2 tablespoons lemon juice
  • 1/4 cup sugar
  • 2 teaspoons cornstarch
  • 1/2 cup powdered sugar
  • 12 tablespoons milk
  • 1/4 teaspoon vanilla extract
  • 2 tablespoons dark chocolate chips, melted (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper.
  2. In a large bowl, cream together butter and granulated sugar until light and fluffy.
  3. Add flour and salt, and mix until a crumbly dough forms.
  4. Press the dough evenly into the bottom of the prepared baking dish.
  5. Bake the crust for 18–20 minutes until lightly golden.
  6. While the crust bakes, combine blueberries, lemon zest, lemon juice, sugar, and cornstarch in a bowl.
  7. Once the crust is baked, pour the blueberry mixture evenly over the warm crust.
  8. Return to the oven and bake for 20–25 minutes, or until the blueberry filling is bubbly and the edges are golden brown.
  9. Let the bars cool completely in the pan.
  10. Mix powdered sugar, vanilla extract, and 1–2 tablespoons of milk to form a smooth vanilla drizzle.
  11. Drizzle the vanilla glaze over the cooled bars.
  12. If using, melt dark chocolate chips and drizzle over the top for an added touch.
  13. Cut into bars and garnish with fresh blueberries if desired.

Notes

  • Use parchment paper for easy removal and clean edges when slicing.
  • Frozen blueberries can be used, but thaw and drain them first.
  • Chill the bars in the fridge for easier cutting and a firmer texture.
