Ingredients

For the Lemon Brownie Base

• 1 cup all-purpose flour – Gives these brownies their structure without being too cakey.
• 1 cup granulated sugar – Sweetens the brownies and complements the tart lemon flavor.
• ½ cup unsalted butter, melted – Adds richness and helps create that signature fudgy texture.
• 2 large eggs – Binds everything together and adds moisture.
• 2 tablespoons lemon zest (from about 2 lemons) – Packs a citrus punch and infuses the batter with fresh aroma.
• 2 tablespoons lemon juice – Brightens the flavor and balances the sweetness.
• ½ teaspoon baking powder – Just a touch to give these brownies a gentle lift.
• ¼ teaspoon salt – Enhances all the other flavors.

For the Lemon Glaze

• 1 cup powdered sugar – Creates a smooth, sweet glaze that sets beautifully.
• 2–3 tablespoons lemon juice – Adjust to your taste for the perfect drizzle consistency.
• ½ tablespoon lemon zest (optional) – For an extra zing and a pop of color on top.

Instructions

1. Preheat and Prep
   Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it. This ensures the lemon brownies lift out easily after baking.
2. Make the Lemon Brownie Batter
   In a large mixing bowl, whisk together the melted butter and granulated sugar until smooth and glossy. Add in the eggs, lemon zest, and lemon juice. Whisk until fully combined.
3. Combine Dry Ingredients
   In a separate bowl, whisk together the flour, baking powder, and salt. Slowly add the dry mixture into the wet ingredients, stirring gently until no flour streaks remain. Be careful not to overmix—just until it’s smooth.
4. Pour and Bake
   Pour the batter into your prepared pan and smooth the top. Bake for 20–24 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out with just a few moist crumbs.
5. Cool Completely
   Let the lemon brownies cool in the pan for about 10 minutes, then transfer to a wire rack. They need to cool completely before glazing to prevent the glaze from melting.
6. Make the Lemon Glaze
   In a small bowl, whisk together the powdered sugar and lemon juice until smooth. If you like extra zing, stir in a little lemon zest.
7. Glaze and Set
   Once the brownies are cool, pour the glaze over the top and spread it evenly. Let it set for at least 15 minutes before slicing into squares.

Tips & Variations

Tips for Perfect Lemon Brownies

• Use fresh lemon juice and zest: Bottled lemon juice can’t match the brightness of freshly squeezed lemons. Zest adds another level of flavor that makes these brownies irresistible.
• Don’t overbake: You’re aiming for a chewy texture, not a cake-like one. Start checking around 20 minutes and pull them when the edges are lightly golden.
• Cool before glazing: If the brownies are warm, the glaze will melt and soak in. Let them cool completely for a glossy, beautiful finish.
• For clean cuts: Chill the brownies in the fridge for 30 minutes before slicing, and use a sharp knife cleaned between each cut.

Flavor Variations

• Lemon-lime twist: Add a splash of lime juice and a bit of zest for a citrus medley.
• Berry boost: Fold in a handful of fresh blueberries or raspberries into the batter before baking.
• Lavender lemon: Add ½ teaspoon of dried culinary lavender for a floral flair.

Diet-Friendly Substitutions

• Gluten-free: Substitute with a 1:1 gluten-free baking flour.
• Dairy-free: Use plant-based butter and check that your glaze ingredients are dairy-free.

Storage Tips

• Room temperature: Store in an airtight container for up to 4 days.
• Refrigerated: Keeps well in the fridge for up to a week.
• Freezer-friendly: Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and enjoy!

FAQs

1. Can I use bottled lemon juice instead of fresh lemons?

Fresh lemon juice gives the best bright, zesty flavor, especially when paired with lemon zest. Bottled juice works in a pinch, but the taste won’t be as vibrant.

2. How do I know when lemon brownies are done baking?

They should be set in the middle but still slightly soft. A toothpick inserted in the center should come out with moist crumbs—not wet batter. Don’t overbake, or you’ll lose the fudgy texture.

3. Can I make these lemon brownies gluten-free?

Yes! Swap the all-purpose flour for a 1:1 gluten-free baking blend. Just be sure your flour includes xanthan gum for structure.

4. Should I refrigerate lemon brownies?

They can sit at room temp in an airtight container for up to 3 days. If you want them firmer (and extra chewy), refrigerate them. The glaze sets beautifully when chilled.

5. Can I freeze lemon brownies?

Absolutely. Freeze them unglazed, then thaw and glaze before serving. Wrap tightly in plastic wrap and freeze for up to 2 months.

6. Can I double this recipe for a crowd?

Definitely! Just bake in a 9×13-inch pan and adjust baking time (add 5–10 minutes). Keep an eye on the center for doneness.
