You want bright, zesty lemon flavor in a fudgy bar? This recipe translates professional technique into simple steps for the best homemade lemon brownies, complete with a tangy lemon glaze.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tablespoon pure vanilla extract
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 cup fresh lemon juice
  • 2 tablespoons fresh lemon zest
  • 1/2 cup powdered sugar (for glaze)
  • 12 tablespoons fresh lemon juice (for glaze)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×9 inch metal baking pan with parchment paper, leaving an overhang on two sides for easy removal. Lightly grease the paper.
  2. In a large bowl, whisk the melted butter and granulated sugar together until fully combined. This step builds the fudgy structure.
  3. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate small bowl, whisk together the flour, baking powder, and salt.
  5. Gradually add the dry ingredients to the wet ingredients. Mix only until just combined; do not overmix. Overmixing develops gluten, which leads to cakey, not fudgy, results.
  6. Stir in the 1/4 cup of lemon juice and the lemon zest until incorporated.
  7. Spread the batter evenly into the prepared pan.
  8. 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. This indicates a fudgy texture.
  9. Let the brownies cool completely in the pan on a wire rack. Cooling is key for clean cuts.
  10. Prepare the glaze: Whisk the powdered sugar with 1 tablespoon of lemon juice until smooth. Add more lemon juice, half a teaspoon at a time, until you reach a thick but pourable consistency.
  11. Once the brownies are cool, drizzle the lemon glaze evenly over the top. Let the glaze set before cutting into squares.

Notes

  • For the most intense lemon flavor, use fresh lemons for both juice and zest. Bottled juice does not provide the same brightness.
  • If you prefer a slightly thicker, chewier bar, reduce the baking time by 2-3 minutes.
  • These lemon brownies freeze well. Cool completely, cut, and store in an airtight container between layers of wax paper in the freezer for up to one month.
