Equipment

  • 1 9x9-inch baking pan lined with parchment paper
  • 1 Large bowl
  • 1 Whisk
  • 1 Spatula

Ingredients
  

  • 1.5 cups all-purpose flour
  • 1 cup granulated sugar
  • 0.5 cup unsalted butter melted and slightly cooled
  • 2 eggs
  • 0.25 cup fresh lemon juice
  • 2 tbsp lemon zest
  • 0.25 tsp salt
  • 1 tsp alcohol-free vanilla
  • 1 cup powdered sugar for the glaze
  • 2 tbsp lemon juice for the glaze

Instructions
 

  • Preheat your oven and line your baking pan with parchment paper. This makes lifting the brownies out much easier once they have cooled.
  • In a large bowl, whisk together the melted butter, sugar, eggs, lemon juice, lemon zest, and alcohol-free vanilla until smooth and well combined.
  • Add the flour and salt, then stir just until the batter comes together. Do not overmix, or the brownies can turn dense.
  • Spread the batter evenly into the prepared pan and bake until the top is set and lightly golden. A toothpick inserted in the center should come out with a few moist crumbs.
  • Let the brownies cool slightly, then whisk together the powdered sugar and lemon juice for the glaze. Spread it over the top and allow it to set before slicing.

Notes

Use freshly grated lemon zest for the strongest flavor, because it carries the oils that make the brownies smell and taste so vibrant. Let the brownies cool before glazing, so the topping stays glossy instead of melting into the cake. For clean slices, chill them briefly before cutting with a sharp knife.

Best Lemon Brownies Ingredients & Substitutions

  • All-purpose flour, gives the brownies structure.
  • Granulated sugar, for sweetness and a light crumb.
  • Unsalted butter, melted and slightly cooled.
  • Eggs, for richness and binding.
  • Fresh lemon juice, for bright citrus flavor.
  • Lemon zest, for a stronger lemon aroma.
  • Salt, to balance the sweetness.
  • Alcohol-free vanilla, adds warmth to the batter.
  • Powdered sugar, for the glaze.

If you need a small swap, you can use extra zest for a bolder lemon taste, or add a spoonful of milk to the glaze if you want it a little thinner. Fresh lemons give the best flavor, but bottled lemon juice can work in a pinch.
