Ingredients for Lemon Brownies

To create the perfect lemon brownies, you’ll need the following ingredients:

  • 1 cup (2 sticks) unsalted butter, melted
  • 1 1/2 cups granulated sugar
  • 2 large eggs
  • 1/4 cup freshly squeezed lemon juice
  • 1 tablespoon lemon zest
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt

For the Lemon Glaze:

  • 1 cup powdered sugar
  • 2-3 tablespoons freshly squeezed lemon juice
  • 1 teaspoon lemon zest

Step-by-Step Recipe

1. Preparing the Batter

Begin by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it to prevent the brownies from sticking.


  • Ensure your butter is fully melted but not hot to avoid cooking the eggs when mixed.
  • Freshly squeezed lemon juice and zest provide the best flavor, so avoid using bottled lemon juice if possible.

2. Mixing Wet Ingredients

In a large mixing bowl, combine the melted butter and granulated sugar. Mix until well blended. Add the eggs, one at a time, beating well after each addition. Stir in the lemon juice and lemon zest until thoroughly combined.


  • Beat the eggs well to incorporate air, which helps give the brownies a light texture.
  • Lemon zest adds intense citrus flavor, so don’t skip this step.

3. Combining Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix, as this can make the brownies dense.


  • Sift the flour to avoid lumps and ensure an even texture in your brownies.
  • Adding the dry ingredients gradually helps prevent clumping.

4. Baking the Brownies

Pour the batter into the prepared baking pan, spreading it evenly with a spatula. Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.


  • Rotate the pan halfway through baking to ensure even cooking.
  • Be careful not to overbake; the brownies should be moist and chewy, not dry.

5. Preparing the Lemon Glaze

While the brownies are baking, prepare the lemon glaze. In a medium bowl, whisk together the powdered sugar, lemon juice, and lemon zest until smooth. Adjust the consistency by adding more lemon juice if needed.


  • For a thicker glaze, use less lemon juice. For a thinner glaze, add more.
  • Sifting the powdered sugar before mixing can help achieve a smoother glaze.

6. Glazing the Brownies

Once the brownies are done, remove them from the oven and let them cool in the pan for about 10 minutes. While still slightly warm, pour the lemon glaze over the top, spreading it evenly. Allow the brownies to cool completely before cutting into squares.


  • Glazing the brownies while warm allows the glaze to seep in slightly, enhancing the flavor.
  • Use a sharp knife to cut clean squares and wipe the knife between cuts for neat edges.

7. Serving and Storing

Lemon brownies can be served immediately or stored for later. They are best enjoyed fresh but can be kept in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.


  • For added presentation, garnish with a light dusting of powdered sugar or extra lemon zest before serving.
  • Refrigerated brownies should be allowed to come to room temperature before serving for the best texture and flavor.

Variations and Add-Ons

1. Lemon Blueberry Brownies

Add 1/2 cup of fresh or frozen blueberries to the batter before baking. The combination of tart lemon and sweet blueberries creates a delightful contrast in flavors.


  • If using frozen blueberries, do not thaw them before adding to the batter to prevent excess moisture.

2. Lemon Poppy Seed Brownies

Mix 2 tablespoons of poppy seeds into the batter for a subtle crunch and a classic flavor pairing. This variation adds texture and a slight nutty flavor.


  • Soak the poppy seeds in the lemon juice for a few minutes before adding to the batter to enhance their flavor.

3. Cream Cheese Lemon Brownies

Swirl 1/2 cup of softened cream cheese into the batter for a rich, creamy addition. Drop spoonfuls of cream cheese on top of the batter and use a knife to create a marbled effect.


  • Soften the cream cheese by leaving it at room temperature or microwaving for a few seconds.

Troubleshooting Common Issues

1. Brownies are Too Dense

If your brownies turn out too dense, it could be due to overmixing the batter or using too much flour. Ensure you measure the flour accurately and mix until just combined.

2. Brownies are Too Dry

Dry brownies are usually a result of overbaking. Keep a close eye on the baking time and test for doneness a few minutes before the suggested baking time.

3. Glaze is Too Runny

If the glaze is too runny, add more powdered sugar to thicken it. Conversely, if it’s too thick, add a small amount of lemon juice until the desired consistency is reached.


Lemon brownies are a refreshing and zesty treat that bring a delightful twist to traditional brownies. With their perfect balance of sweet and tart, these brownies are sure to become a favorite in your baking repertoire. By following this guide, you can create delicious lemon brownies that are moist, flavorful, and beautifully glazed.
