Make moist, fudgy lemon brownies topped with a simple, tangy lemon glaze. This recipe is straightforward and produces a rich, bright citrus dessert bar.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1/4 cup fresh lemon juice
  • Zest of 2 large lemons
  • 1 cup powdered sugar (for glaze)
  • 2 tablespoons fresh lemon juice (for glaze)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper.
  2. In a large bowl, whisk the melted butter and granulated sugar together until combined.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, cocoa powder, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  6. Gently fold in the 1/4 cup of lemon juice and the lemon zest until evenly distributed.
  7. Spread the batter evenly into the prepared baking pan.
  8. Bake for 25 to 30 minutes. A toothpick inserted near the center should come out with moist crumbs attached, not wet batter.
  9. Let the brownies cool completely in the pan on a wire rack.
  10. Prepare the glaze: Whisk together the powdered sugar and 2 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.
  11. Once the brownies are cool, drizzle the glaze over the top. Let the glaze set before cutting into squares.

Notes

  • For extra fudgy texture, slightly underbake the brownies by about 2 minutes.
  • Use fresh lemon juice for the best, brightest flavor in both the brownie and the glaze.
  • If you prefer a chewier bar, reduce the baking time slightly.
