  • 1/2 tspbaking soda: Another leavening agent that aids in the bars' light texture.
  • 1/2 tspsalt: Balances the overall sweetness and enhances flavor.
  • 1 cupfresh or frozen blueberries: The star ingredient (providing bursts of juicy flavor throughout the bars.)

Instructions

  1. 1

    Preheat the oven: Begin by preheating your oven to 350°F (175°C) and greasing a 9x13 inch baking pan to ensure easy removal of the bars later.

  2. 2

    Cream the butter and sugars: In a large mixing bowl, use an electric mixer to cream together 1 cup unsalted butter, 1 cup granulated sugar, and 1 cup brown sugar until the mixture is smooth and fluffy, approximately 3-4 minutes.

  3. 3

    Add the eggs and vanilla: Incorporate 2 large eggs and 1 tsp vanilla extract into the creamed mixture, mixing well until completely combined.

  4. 4

    Combine the dry ingredients: In another bowl, whisk together 2 cups all-purpose flour, 1 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp salt until evenly mixed.

  5. 5

    Mix dry into wet: Gradually add the dry ingredients to the creamed mixture, mixing on low speed until just combined. Avoid overmixing to keep the bars tender.

  6. 6

    Fold in the blueberries: Gently fold in 1 cup fresh or frozen blueberries, the zest & juice of 1 lemon, ensuring even distribution without breaking the berries.

  7. 7

    Spread the batter: Pour the batter into the prepared pan, using a spatula to smooth it evenly.

  8. 8

    Bake: Bake in the preheated oven for 30-35 minutes. The bars are done when a toothpick inserted into the center comes out clean.

  9. 9

    Cool and drizzle: Allow the bars to cool in the pan for about 10 minutes. Once slightly cooled, melt 1 cup white chocolate chips in the microwave or over a double boiler, then drizzle over the cooled bars.

  10. 10

    Cut and serve: Allow the chocolate to set before cutting the bars into squares for serving. Enjoy!
