Create these easy lemon brownies for a refreshing twist on classic desserts. They have a moist, fudgy texture and are topped with a bright, zesty lemon glaze, making them perfect for spring and summer baking.

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 1/2 cups all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup powdered sugar (for glaze)
  • 1 tablespoon fresh lemon juice (for glaze)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a large bowl, whisk the melted butter and granulated sugar together until combined.
  3. Whisk in the eggs one at a time until fully incorporated.
  4. Stir in the lemon zest, lemon juice, and vanilla extract until the mixture is smooth.
  5. In a separate small bowl, whisk together the flour and salt.
  6. Gradually add the dry ingredients to the wet ingredients, mixing only until just combined. Do not overmix.
  7. Pour the batter into the prepared baking pan and spread evenly.
  8. Bake for 25 to 30 minutes, or until a toothpick inserted near the center comes 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 the powdered sugar and 1 tablespoon of lemon juice together until smooth. Add more powdered sugar or juice, one teaspoon at a time, to 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 slicing into squares.

Notes

  • For extra zesty flavor, use fresh lemons only; bottled juice does not provide the same brightness.
  • To achieve a fudgy texture, avoid overbaking; check for moist crumbs rather than a completely clean toothpick.
  • You can substitute white chocolate chips into the batter for a Lemon White Chocolate Brownie variation.
