Description
These vibrant, zesty lemon blackberry blondies offer the perfect balance of sweetness and tartness with a rich, moist texture. Topped with a smooth lemon glaze, they’re an irresistible treat for any occasion.
Ingredients
- For the Blondies:
- 1⅓ cups frozen blackberries
- ½ cup unsalted butter, softened
- 1 cup white sugar
- ½ teaspoon salt
- 1 tablespoon freshly grated lemon zest
- 1 tablespoon fresh lemon juice
- ½ teaspoon vanilla extract
- 1 cup plus 2 tablespoons all-purpose flour
- 1 tablespoon cornstarch
- ½ teaspoon baking powder
- For the Glaze:
- 1 cup confectioners sugar
- 1 pinch salt
- 2 teaspoons lemon juice (or as needed)
- 1 tablespoon heavy cream (or as needed)
Instructions
- Preheat the oven to 350°F (180°C). Line an 8×8-inch square pan with parchment paper, ensuring there’s enough overhang to lift the blondies out easily later.
- In a microwave-safe bowl, place the frozen blackberries and microwave for about 2 minutes, until thawed. Do not drain the juice.
- In a large bowl, beat together the butter, sugar, and salt using an electric mixer until light and fluffy, about 3 minutes.
- Add the blackberries and their juices, lemon zest, lemon juice, and vanilla to the bowl, and continue beating for about 3 minutes until the blackberries are broken down and fully incorporated. The mixture will look slightly curdled.
- Mix in the flour, cornstarch, and baking powder on low speed until just combined.
- Pour the batter into the prepared pan and spread into an even layer.
- Bake in the preheated oven for 30–35 minutes, or until the bars are puffed and almost set but still soft in the middle.
- Remove from the oven and allow the bars to cool completely in the pan, about 20 minutes.
- For the glaze, whisk together the confectioners sugar, salt, lemon juice, and heavy cream until smooth. Add more lemon juice or heavy cream as needed to achieve a pourable consistency.
- Pour the glaze over the cooled bars and spread it evenly. Let the glaze set for about 15 minutes.
- Lift the blondies from the pan using the parchment paper overhang and cut into 16 pieces.
Notes
- For an added touch, sprinkle extra lemon zest or blackberries on top of the glaze before it sets.
- If you prefer a thicker glaze, add less heavy cream, or a thinner glaze by adding more lemon juice or cream.
- Store the blondies in an airtight container for up to 4 days at room temperature, or freeze for longer storage.
