Ingredients Equipment Method Notes

Ingredients
  

For the Lemon Brownies
  • ¾ cup all-purpose flour
  • ¾ cup granulated sugar
  • ½ cup unsalted butter melted
  • ½ teaspoon sea salt
  • 3 large eggs
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon lemon zest
  • 1 teaspoon vanilla extract
For the Lemon Glaze
  • 1 cup powdered sugar
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon lemon zest

Equipment

  • Mixing bowl
  • whisk
  • Rubber spatula
  • Baking pan (8 inches square)

Method
 

  1. Preheat the Oven: Set your oven to 350°F (175°C). Grease an 8-inch square baking dish or line it with parchment paper for easy removal.
Prepare the Batter
  1. In a large mixing bowl, whisk together the melted butter and granulated sugar until well combined.
  2. Add the eggs one at a time, whisking thoroughly after each addition.
  3. Stir in the lemon zest, lemon juice, and vanilla extract until the mixture is smooth.
  4. In a separate bowl, combine the flour and sea salt. Gradually fold this dry mixture into the wet ingredients until just combined. Be careful not to overmix.
Bake
  1. Pour the batter into the prepared baking dish, spreading it evenly.
  2. Bake for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
  3. Allow the brownies to cool completely in the pan on a wire rack.
Prepare the Glaze
  1. In a medium bowl, whisk together the powdered sugar, lemon juice, and lemon zest until smooth.
  2. Once the brownies are cool, pour the glaze over the top, spreading it evenly.
  3. Let the glaze set before cutting the brownies into squares.

Notes

  • For a bolder lemon flavor, use Meyer lemons, which are sweeter and more fragrant than regular lemons.
  • Avoid overmixing the batter—this will keep your brownies soft, fluffy, and tender.
  • Allow the brownies to cool completely before adding the glaze. If they’re too warm, the glaze will melt into the brownies instead of resting on top.
  • If you desire a thicker glaze, slightly reduce the amount of lemon juice or sift the powdered sugar before mixing for a smoother result consistency.
