Ingredients

Scale
  • 1 cup (227g) unsalted butter, melted
  • 2 cups (400g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 cups (250g) all-purpose flour (or almond flour for gluten-free)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • Zest of 2 lemons (about 2 tablespoons)
  • 1 1/2 cups (225g) fresh blackberries
  • 1 cup (120g) powdered sugar, sifted
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon finely grated lemon zest
  • 1 teaspoon finely grated orange zest
  • 12 teaspoons milk or water (optional, to adjust glaze consistency)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease or line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy removal.
  2. In a large bowl, whisk together the melted butter and light brown sugar until smooth and glossy, about 2-3 minutes.
  3. Add the eggs one at a time, mixing well after each addition. Stir in vanilla extract and lemon zest.
  4. In a separate medium bowl, sift together the flour, baking powder, and salt.
  5. Gradually fold the dry ingredients into the wet ingredients with a spatula until just combined; avoid overmixing.
  6. Gently fold in the fresh blackberries, being careful not to break them up.
  7. Pour the batter into the prepared pan and smooth the top gently.
  8. Bake for 30-35 minutes, until edges are golden and a toothpick inserted near the center comes out with a few moist crumbs.
  9. Cool completely on a cooling rack, about 45 minutes.
  10. Prepare the glaze by whisking powdered sugar, lemon juice, lemon zest, orange zest, and a splash of milk or water until smooth. Adjust consistency as needed.
  11. Drizzle the glaze over the cooled blondies and let set for at least 15 minutes.
  12. Slice into squares using a sharp knife, wiping the knife clean between cuts, and serve.

Notes

Do not overmix the batter to keep blondies tender. Use fresh lemon zest for best flavor. Gently fold in blackberries to avoid breaking them. Cool completely before glazing to prevent glaze from running. For dairy-free, substitute butter with coconut oil or vegan butter and use plant-based milk in glaze. Frozen blackberries can be used if thawed and drained well to avoid sogginess.
