These bars have a soft chewy texture similar to blondies, with the freshness of citrus and the natural sweetness of berries. They are simple to prepare in one pan, slice beautifully for serving, and always look inviting on dessert trays.
Ingredients
- ½ cup unsalted butter, melted
- ¾ cup granulated sugar
- 1 large egg
- 1 tablespoon fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon vanilla extract
- 1½ cups all-purpose flour
- ½ teaspoon baking powder
- ¼ teaspoon salt
- ¾ cup fresh or frozen blueberries
For the Lemon Glaze
- ¾ cup powdered sugar
- 1–2 tablespoons fresh lemon juice
Preparation Steps
Step 1: Prepare the Batter
In a large mixing bowl, whisk together the melted butter and granulated sugar until smooth and glossy. Add the egg, lemon juice, lemon zest, and vanilla extract. Mix well until the mixture becomes creamy and slightly thickened.
Step 2: Combine Dry Ingredients
In a separate bowl, whisk the flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture using a spatula or wooden spoon. Stir gently just until a soft batter forms.
Step 3: Add the Blueberries
Carefully fold in the blueberries. If using frozen berries, do not thaw them first to avoid excess moisture and color bleeding into the batter.
Step 4: Spread and Bake
Line an 8×8-inch baking pan with parchment paper. Spread the batter evenly into the pan using an offset spatula. Bake in a preheated oven at 350°F (175°C) for 22–26 minutes or until the edges are lightly golden and the center is set.
Step 5: Cool Completely
Remove the pan from the oven and allow the bars to cool fully before glazing. This helps the bars firm up and makes slicing easier and cleaner.
Step 6: Add the Lemon Glaze
In a small bowl, whisk powdered sugar with lemon juice until smooth and pourable. Drizzle the glaze evenly over the cooled bars using a spoon or piping bag. Let the glaze set for 10–15 minutes before slicing.
Variations
- Substitute raspberries or blackberries for a different berry flavor profile.
- Add white chocolate chips for extra sweetness and creamy texture.
- Mix a tablespoon of cream cheese into the glaze for a richer topping.
- Sprinkle coarse sugar on top before baking for a light crunch.
- Add shredded coconut for a tropical citrus twist.
Cooking Notes
- Do not overmix the batter once flour is added to keep the bars tender.
- Use fresh lemon zest for the strongest natural citrus aroma.
- Bake just until the center is set to prevent dryness.
- Let the bars cool fully in the pan for clean slicing results.
- If using very juicy berries, lightly toss them in flour before folding into the batter.
