Lemon Brownies are a bright and cheerful twist on the classic chocolate treat. These brownies blend the sweet tang of fresh lemon with a soft, cakey texture that feels like a little burst of sunshine in every bite. With a lightly golden top and a moist, tender crumb, they’re a refreshing way to enjoy a dessert that’s not too heavy but still feels special.
I love making lemon brownies when I want something a little different from the usual chocolate options. The lemon zest and juice really pop through, giving the brownies a zesty kick that keeps me coming back for more. They’re easy to whip up, and the kitchen always smells amazing while they bake. Plus, I find that they stay nicely moist for days, so they’re great for having around for a quick sweet snack.
My favorite way to enjoy these is with a dusting of powdered sugar or a simple drizzle of glaze made from lemon juice and sugar. They’re perfect for sharing at a casual get-together or packing in a lunchbox for a fresh, tasty treat. Whenever I serve lemon brownies, people always tell me how surprisingly delicious and uplifting they are—like a little slice of sunshine on a plate!
Key Ingredients & Substitutions
Butter: Melted unsalted butter gives the brownies richness and moisture. If you want a dairy-free option, try coconut oil or a vegan butter substitute. I find butter gives the best flavor, but coconut oil adds a nice hint of tropical taste.
Lemon Zest & Juice: Fresh lemon zest and juice provide the bright, tangy flavor that defines these brownies. Avoid bottled lemon juice for the best fresh taste. If lemons aren’t available, lime zest and juice can make a tasty twist.
Flour: All-purpose flour works well here for the tender crumb. You can substitute a gluten-free all-purpose blend if needed, just make sure it contains xanthan gum or a binder for good texture.
Sugar: Granulated sugar adds sweetness and helps with texture. You can reduce the sugar slightly if you prefer a less sweet treat or experiment with coconut sugar for a deeper flavor.
How Do You Get Moist and Tender Lemon Brownies?
The key to moist lemon brownies is careful mixing and baking:
- Mix the melted butter and sugar thoroughly for even texture.
- Add eggs one at a time and beat well to create a smooth batter.
- Fold in dry ingredients gently — overmixing can make the brownies tough.
- Don’t overbake; start checking a few minutes early. The toothpick should come out with a few crumbs, not completely dry.
- Let the brownies cool fully before glazing to avoid melting the topping.
Following these steps helps the brownies stay soft with a delicate crumb that melts in your mouth, balanced by a fresh lemon zing.

Equipment You’ll Need
- 9×13 inch baking pan – I like using this size because it’s perfect for even baking and easy to cut into squares.
- Mixing bowls – a large one for combining ingredients and a small one for the glaze make the process smooth.
- Whisk or electric mixer – helps blend everything smoothly, especially when beating the eggs into the mixture.
- Measuring cups and spoons – for accurate ingredient amounts so the brownies turn out just right.
- Rubber spatula – for scraping the batter into the pan and spreading it evenly.
- Small bowl & whisk – for mixing the lemon glaze quickly and smoothly.
- Parchment paper (optional) – makes removing the brownies easier and cleaning up less messy.
Flavor Variations & Add-Ins
- Blueberries or chopped fresh strawberries – fold in berries to add fruity bursts that pair nicely with lemon.
- Replace vanilla with almond extract – gives a slightly nutty, richer flavor for a different twist.
- Top with shredded coconut or chopped nuts – add texture and extra flavor on top before baking or glazing.
- Use lime or orange zest and juice instead of lemon for a different citrus flavor profile.
How to Make Lemon Brownies?
Ingredients You’ll Need:
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 tablespoon lemon zest (from about 2 lemons)
- ¼ cup fresh lemon juice
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- ½ teaspoon baking powder
- ¼ teaspoon salt
For the lemon glaze:
- 1 cup powdered sugar
- 2-3 tablespoons fresh lemon juice
- 1 teaspoon lemon zest (optional, for garnish)
How Much Time Will You Need?
Preparing these lemon brownies takes about 15 minutes. Baking time is 25 to 30 minutes, and you’ll want to let them cool completely before adding the glaze, which can take another 20-30 minutes to set. All in all, plan for about 1 hour from start to finish.
Step-by-Step Instructions:
1. Get Ready:
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper to make removing the brownies easier.
2. Mix the Batter:
In a large bowl, whisk the melted butter with the granulated sugar until smooth. Add the eggs one at a time, mixing well after each. Stir in the lemon zest, lemon juice, and vanilla extract.
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually fold these dry ingredients into the wet mixture, mixing just until combined — don’t overmix or the brownies might get tough.
3. Bake:
Pour the batter into your prepared pan and spread it evenly. Bake for about 25-30 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean or with a few moist crumbs.
4. Cool and Glaze:
Let the brownies cool completely in the pan on a wire rack. Meanwhile, mix the powdered sugar and lemon juice in a small bowl until smooth. Adjust the glaze’s thickness as needed by adding more juice or sugar.
Spread the glaze over the cooled brownies, sprinkle with lemon zest if you like, and let it set before cutting into squares and serving.
Enjoy your fresh, tangy, and moist lemon brownies perfect for any occasion!
Can I Use Frozen Lemon Juice or Zest?
Yes! If you don’t have fresh lemons on hand, frozen lemon juice and zest work well. Just thaw the juice completely and drain any excess liquid before adding to avoid extra moisture in the batter.
How Should I Store Leftover Lemon Brownies?
Store leftovers in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. For longer storage, freeze them for up to 3 months — just thaw at room temperature before serving.
Can I Make These Lemon Brownies Gluten-Free?
Absolutely! Substitute the all-purpose flour with a gluten-free blend that contains xanthan gum. The texture might be slightly different but still delicious and moist.
Is There a Way to Make the Glaze Thicker or Thinner?
Yes! Add more powdered sugar to thicken the glaze or a little extra lemon juice to thin it out. Adjust gradually to get your preferred consistency for easy spreading.
