I’ve spent countless afternoons perfecting this recipe to ensure it delivers that ideal contrast in every bite.

Why You’ll Love These Lemon Brownies
If you’ve ever struggled with lemon desserts that turn out too sour, too sweet, or disappointingly bland, these Lemon Brownies solve that common baking challenge beautifully. The precise balance of ingredients ensures you get that perfect citrus flavor without overwhelming tartness. Unlike traditional lemon bars that require finicky shortbread crusts or fussy multi-step techniques, this recipe is wonderfully forgiving and comes together in a single bowl for the base.
I first developed these Lemon Brownies for a spring brunch where I wanted something bright and unique to serve alongside more traditional pastries. My mother-in-law, who typically turns her nose up at anything other than chocolate desserts, took one polite bite and immediately asked for the entire recipe. Since then, they’ve become my most requested contribution to family gatherings, potlucks, and neighborhood events.
What I love most about these Lemon Brownies is their incredible versatility. They’re elegant enough for afternoon tea but casual enough for lunchboxes. They can be dressed up with a dollop of whipped cream and berries for a sophisticated dessert or enjoyed plain with your morning coffee. You can easily adjust the lemon intensity, swap in different citrus fruits, or add complementary flavors like berries or herbs to customize them to your taste.
Now, let’s dive into exactly what you’ll need to create these sunny treats.
Ingredients for Lemon Brownies
For the Brownie Base
- 1 cup all-purpose flour: The foundation of our Lemon Brownies. For a lighter texture, you can substitute cake flour. For gluten-free Lemon Brownies, use a 1:1 gluten-free flour blend that contains xanthan gum.
- 1/2 teaspoon salt: Enhances all the flavors and balances the sweetness. I prefer fine sea salt for its clean taste, but table salt works well too.
- 1/4 teaspoon baking powder: Provides just enough lift without making the Lemon Brownies cakey. Aluminum-free varieties prevent any metallic aftertaste.
- 3/4 cup granulated sugar: Creates the perfect level of sweetness to complement the lemon. Can be reduced to 2/3 cup if you prefer less sweet desserts.
- 2 tablespoons lemon zest (from about 2 lemons): The essential ingredient that gives our Lemon Brownies their bright flavor. Use organic lemons if possible since you’re using the zest. Be sure to zest only the yellow part, as the white pith is bitter.
- 1/2 cup unsalted butter, melted and slightly cooled: Provides richness and that classic brownie texture. For dairy-free Lemon Brownies, substitute with coconut oil or vegan butter.
- 2 large eggs, at room temperature: Binds everything together and contributes to the fudgy texture. Room temperature eggs incorporate better into the batter.
- 1/4 cup fresh lemon juice (from about 2 lemons): Delivers that bright, tangy flavor. Always use fresh juice rather than bottled for the best flavor in your Lemon Brownies.
- 1 teaspoon vanilla extract: Rounds out the flavor profile and enhances the buttery notes. Pure vanilla extract provides the best flavor.
- 1/4 teaspoon lemon extract (optional): For extra lemon intensity in your Lemon Brownies. Can be omitted if you don’t have it on hand.
For the Lemon Glaze
- 1 cup powdered sugar, sifted: Creates a smooth, sweet glaze that sets beautifully. Sifting prevents lumps in your Lemon Brownies’ glaze.
- 2-3 tablespoons fresh lemon juice: Thins the glaze to the perfect consistency while adding more tangy lemon flavor. Start with less and add more as needed.
- 1 tablespoon lemon zest: For visual appeal and an extra burst of flavor on top of your Lemon Brownies.
- Pinch of salt: Balances the sweetness of the glaze and enhances the lemon flavor.
How to Make Lemon Brownies
Step 1: Prepare Your Baking Pan
- Preheat your oven to 350°F (175°C). Position the rack in the center of the oven.
- Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides to easily lift out the Lemon Brownies later. This “parchment sling” is crucial for clean, easy removal.
- Lightly grease any exposed parts of the pan with butter or cooking spray.
Step 2: Infuse the Sugar
- In a large bowl, combine the granulated sugar and lemon zest.
- Using your fingertips, rub the zest into the sugar until fragrant and slightly moist. This releases the essential oils from the zest, intensifying the lemon flavor throughout your Lemon Brownies.
- The sugar will become slightly yellow and very aromatic – you’ll know it’s ready when you can smell the bright lemon fragrance with each breath.
Step 3: Mix the Batter
- Add the melted butter to the lemon-infused sugar and whisk until completely combined.
- Add the eggs one at a time, whisking well after each addition until the mixture looks smooth and glossy.
- Stir in the lemon juice, vanilla extract, and lemon extract (if using). The mixture may look slightly curdled, but this is normal and will smooth out when you add the dry ingredients.
- In a separate bowl, whisk together the flour, salt, and baking powder.
- Gradually add the dry ingredients to the wet ingredients, folding gently with a spatula just until combined. Avoid overmixing, which can make your Lemon Brownies tough.
- The batter will be thick and smooth – thicker than a cake batter but not as dense as a traditional chocolate brownie batter.
Step 4: Bake the Lemon Brownies
- Pour the batter into your prepared pan, spreading it evenly into the corners using a spatula.
- Tap the pan gently on the counter a few times to remove any air bubbles.
- Bake for 23-25 minutes, until the edges are just beginning to turn golden and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
- Look for visual cues: the top should no longer appear wet or shiny, and the edges will have pulled away slightly from the sides of the pan.
- Be careful not to overbake – Lemon Brownies should remain fudgy in the center. They will continue cooking slightly as they cool.
Step 5: Prepare the Glaze
- While the brownies are baking, prepare the glaze by whisking together the sifted powdered sugar, 2 tablespoons of lemon juice, lemon zest, and a pinch of salt in a small bowl.
- Add more lemon juice, a teaspoon at a time, until you reach a pourable but still thick consistency. The glaze should ribbon off the whisk when lifted.
- Set aside until the brownies are completely cooled.
Step 6: Finish and Cut
- Allow the Lemon Brownies to cool completely in the pan on a wire rack, about 1 hour. Patience here is key – glazing warm brownies will result in a messy, runny topping.
- Once cooled, lift the brownies out of the pan using the parchment overhang and place on a cutting board.
- Pour the glaze over the brownies, tilting the slab to ensure even coverage. Use an offset spatula to spread if needed.
- Let the glaze set for at least 30 minutes before cutting. For the cleanest cuts, refrigerate for 15 minutes once the glaze has set.
- Using a sharp knife, cut into 16 squares, wiping the knife clean between cuts for the most professional-looking Lemon Brownies.
Delicious Variations of Lemon Brownies
Berry Swirl Lemon Brownies
Before baking, dollop 1/4 cup of raspberry or blueberry preserves over the batter and use a knife to create beautiful swirls throughout. The berry flavor creates perfect pockets of fruity sweetness that complement the tangy lemon in these Lemon Brownies.
Coconut Lemon Brownies
Add 1/2 cup of sweetened shredded coconut to the batter and substitute coconut oil for the butter. Top the glazed Lemon Brownies with toasted coconut flakes for a tropical twist that transports you to an island getaway with every bite.
Lavender Lemon Brownies
Infuse the sugar with 1 tablespoon of dried culinary lavender along with the lemon zest. Strain out the lavender before continuing with the recipe. This elegant, floral version of Lemon Brownies is perfect for spring gatherings and afternoon teas.
White Chocolate Chip Lemon Brownies
Fold 1/2 cup of white chocolate chips into the batter just before baking. The creamy white chocolate creates delightful pockets of sweetness that perfectly balance the tangy lemon in these Lemon Brownies. Drizzle with melted white chocolate instead of glaze for an extra decadent touch.
Meyer Lemon and Thyme Brownies
When in season, use Meyer lemons for a more complex, slightly sweeter citrus flavor. Add 1 teaspoon of fresh thyme leaves to the batter for an unexpected herbal note that elevates these Lemon Brownies to gourmet status.
Lemon Poppy Seed Brownies
Add 2 tablespoons of poppy seeds to the batter for visual appeal and subtle texture. This classic flavor combination transforms your Lemon Brownies into a sophisticated treat reminiscent of beloved bakery muffins but with that coveted dense, chewy texture.

Frequently Asked Questions About Lemon Brownies
How do I store Lemon Brownies?
Store completely cooled Lemon Brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. Place parchment paper between layers if stacking to prevent sticking. The flavor of these Lemon Brownies actually improves on the second day as the lemon infuses more thoroughly.
Can I freeze Lemon Brownies?
Yes! Lemon Brownies freeze beautifully for up to 3 months. For best results, freeze them unglazed, tightly wrapped in plastic wrap and then aluminum foil. Thaw overnight in the refrigerator, then bring to room temperature and add the glaze fresh before serving. If you must freeze glazed Lemon Brownies, freeze them solid on a baking sheet first, then wrap individually to protect the glaze.
My lemon brownies turned out cakey instead of fudgy. What went wrong?
Cakey Lemon Brownies usually result from overmixing the batter or overbaking. Remember to fold the dry ingredients gently just until combined, and watch your baking time carefully. Look for the visual cues mentioned in the recipe rather than relying solely on time. Also, make sure your oven temperature is accurate – an oven thermometer can be helpful.
Can I make these Lemon Brownies gluten-free?
Absolutely! Simply substitute the all-purpose flour with a high-quality 1:1 gluten-free baking flour that contains xanthan gum. The texture may be slightly different, but the flavor will be just as delicious. Some readers have reported excellent results with Cup4Cup and King Arthur Measure for Measure gluten-free flours.
How can I make sure my Lemon Brownies have enough lemon flavor?
For maximum lemon flavor in your Lemon Brownies: 1) Don’t skip the step of rubbing the zest into the sugar, 2) Use fresh lemon juice rather than bottled, 3) Add the optional lemon extract, and 4) Make sure your lemons are fresh and fragrant. If you have access to Meyer lemons when in season, they offer an even more intense flavor profile.
Can I double this recipe for a larger batch?
Yes, this recipe doubles perfectly! Use a 9×13-inch pan and increase the baking time by only 5-7 minutes. Watch carefully for the same visual cues – edges pulling away from the pan and a matte (not shiny) top. Let the larger batch of Lemon Brownies cool completely before glazing and cutting.
A Sweet Conclusion
