Ingredients

Scale
  • 1 cup unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tablespoon lemon zest (from about 2 lemons)
  • 1/4 cup fresh lemon juice
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup white chocolate chips (optional)
  • For the Glaze: 1 1/2 cups powdered sugar
  • For the Glaze: 3 tablespoons fresh lemon juice

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang for easy removal. Lightly grease the paper.
  2. In a large bowl, whisk together the melted butter and granulated sugar until combined.
  3. Whisk in the eggs one at a time until the mixture is smooth.
  4. Stir in the lemon zest, lemon juice, and vanilla extract. Mix until just combined.
  5. In a separate medium bowl, whisk together the flour and salt.
  6. Gradually add the dry ingredients to the wet ingredients, mixing gently until just incorporated. Do not overmix.
  7. Fold in the white chocolate chips, if using.
  8. Spread the batter evenly into the prepared baking pan.
  9. Bake for 25 to 30 minutes. The edges should look set, and a toothpick inserted near the center should come out with moist crumbs attached, not wet batter.
  10. Let the brownies cool completely in the pan on a wire rack.
  11. While cooling, prepare the glaze: Whisk together the powdered sugar and 3 tablespoons of lemon juice until smooth. Add more powdered sugar or lemon juice, one teaspoon at a time, to reach a thick but pourable consistency.
  12. Once the brownies are cool, drizzle the lemon glaze evenly over the top. Let the glaze set before cutting into squares.

Notes

  • For extra bright citrus flavor, use fresh lemon juice only.
  • If you prefer a chewier texture, slightly underbake the brownies by about 2 minutes.
  • These lemon brownies are best stored in an airtight container at room temperature for up to 3 days.
