Description

Delight in these moist and tangy Blueberry Lemon Blondies, combining the sweetness of brown sugar with fresh blueberries and zesty lemon for a refreshing twist on a classic treat. Perfectly baked to golden perfection, these blondies offer a balance of fruity brightness and buttery richness.


Ingredients

Blondie Batter

  • 1/2 cup unsalted butter, melted
  • 1 cup packed brown sugar
  • 1 large egg
  • 1 tablespoon lemon zest
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup fresh blueberries

Decoration (Optional)

  • Powdered sugar for dusting


Instructions

  1. Preheat Oven and Prepare Pan: Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper to prevent sticking and ensure easy removal.
  2. Mix Butter and Sugar: In a medium bowl, whisk together the melted butter and brown sugar until the mixture is smooth and well combined, creating the base for your blondie batter.
  3. Add Wet Ingredients: Incorporate the egg, lemon zest, lemon juice, and vanilla extract into the butter-sugar mixture, whisking until the batter is smooth and uniform.
  4. Combine Dry Ingredients: In a separate bowl, whisk the all-purpose flour, baking powder, and salt together to evenly distribute the leavening agents and seasoning.
  5. Fold Dry Ingredients into Wet Mixture: Gently fold the dry ingredients into the wet mixture until just combined to maintain a tender texture.
  6. Incorporate Blueberries: Carefully fold in the fresh blueberries, ensuring they are evenly distributed without crushing them.
  7. Bake Blondies: Spread the batter evenly in the prepared baking pan and bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  8. Cool and Dust: Allow the blondies to cool completely in the pan, then dust with powdered sugar if desired before cutting into 9 or 10 squares to serve.

Notes

  • Use fresh blueberries for the best texture and flavor; frozen blueberries can be used but may color the batter more.
  • Do not overmix the batter once flour is added to avoid tough blondies.
  • Lemon zest and juice add brightness; adjust quantities for a more or less pronounced lemon flavor.
  • Line the baking pan with parchment paper with some overhang to help lift blondies out easily.
  • Store blondies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend that measures 1:1.
