Ingredients

  • Fresh Blueberries: Juicy, sweet-tart berries add pops of flavor and color throughout the blondies.
  • Fresh Lemon Juice and Lemon Zest: The bright, citrusy notes perfectly complement the blueberries.
  • All-Purpose Flour: It provides structure to the blondies.
  • Baking Powder: The leavening agent helps the blondies rise, creating a light and cakey texture.
  • Salt: It balances the sweetness and brings out the best in the other ingredients.
  • Unsalted Butter: It adds richness, moisture, and a buttery flavor to the blondie base. Using unsalted allows for better control over the total salt content.
  • Granulated Sugar: It provides sweetness and helps create a soft, moist texture.
  • Large Egg: It acts as a binder, holding the ingredients together.
  • Vanilla Extract: It enhances the overall flavor profile with its warm, sweet aroma.
  • Powdered Sugar: It’s used to make the smooth, sweet glaze for the top of the blondies.
  • Frozen Blueberries (for color, optional): They add a gorgeous purple hue!

How to Make Lemon Blueberry Blondies

These blondies are easy enough for beginners! 

1. Prepare. Preheat the oven to 350°F and line an 8×8 inch baking pan with parchment paper.

2. Mix the dry ingredients. In a medium bowl, whisk together the flour, baking powder, and salt.

3. Combine the wet ingredients. In a large bowl, mix the melted butter, sugar, lemon zest, egg, lemon juice, and vanilla.

4. Make the batter. Gradually stir the dry ingredients into the wet ingredients until just combined. Gently fold in the blueberries.

5. Bake the blondies. Pour the batter into the prepared pan and bake for 25-30 minutes until lightly golden.

6. Cool the blondies. Allow the blondies to cool completely in the pan or on a wire rack.

7. Make the lemon glaze. Whisk the powdered sugar and lemon juice for the glaze. Optional: blend frozen blueberries into the juice for color.

8. Glaze and serve. Drizzle the glaze over the cooled blondies. Lift from the pan using parchment, cut into squares, and serve. Enjoy!

Tips for the Best Lemon Blueberry Blondies

These tips and tricks make your blondies bakery-worthy!

  • Room temperature is a must. Ensure your egg is at room temperature for better incorporation and texture.
  • Coat the blueberries. Toss the blueberries with a teaspoon of flour before folding them into the batter. It helps prevent them from sinking to the bottom while baking.
  • Don’t overmix! Mix the batter just until the flour is incorporated to avoid dense, tough blondies.
  • Chill before cutting. For the cleanest slices, chill the glazed blondies in the fridge for 2-3 hours before cutting them into squares.
  • Experiment and have fun. Swap the lemon for lime or orange, add white chocolate chips, or top with streusel.

How to Store

Here’s how to keep your treats nice and fresh.

To Store: Store in an air-tight container at room temperature for up to 3 days, or refrigerate for up to 5-7 days for a chilled texture.

To Freeze: For best results, freeze by wrapping each bar individually in plastic wrap and placing them in a freezer-safe container. They can be stored frozen for up to 3 months. Thaw at room temperature before glazing and serving.

You won’t be able to resist these lemon blueberry blondies! They’re fruity, citrusy, sweet, and such an indulgent treat.

Ingredients

  • Lemon Blueberry Blondies:
  • 1 cup all-purpose flour

  • ¼ teaspoon baking powder

  • ¼ teaspoon salt

  • ½ cup unsalted butter, melted and slightly cooled

  • ¾ cup granulated sugar

  • Zest from 1 large lemon (about 1 tablespoon)

  • 1 large egg, at room temperature

  • ¼ cup freshly squeezed lemon juice

  • 1 teaspoon vanilla extract

  • 1 cup fresh blueberries

  • Lemon Blueberry Glaze:
  • 1 cup powdered sugar, sifted

  • 2 tablespoons lemon juice

  • 1 heaping tablespoon frozen blueberries (for color, optional)

Instructions

  • Preheat the oven to 350°F. Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
  • In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  • In a large bowl, mix the melted butter, sugar, and lemon zest until well combined. Add the egg, lemon juice, and vanilla extract and stir until smooth.
  • Gradually stir the flour mixture into the wet ingredients, mixing just until combined. Gently fold in the blueberries.
  • Pour the batter into the prepared pan and spread evenly. Bake for 25-30 minutes, until lightly golden brown on the edges and a toothpick inserted into the center comes out clean.
  • Allow the blondies to cool completely in the pan set on a wire rack.
  • For the glaze, whisk together the powdered sugar and lemon juice until smooth. For a purple color, pulse the frozen blueberries with the lemon juice in a food processor, then strain out the seeds and mix with the sugar. Drizzle the glaze over the cooled blondies.
  • Lift the blondies out using the parchment paper. Cut into squares and serve.
