Lemon Brownies are dessert bars that are dense and moist with a lemony flavor and topped with a simple glaze. If you love lemon desserts, be sure to try my Strawberry Lemon Blondies and Lemon Bars.
Lemon Brownies
Brownies don’t always have to be chocolate. These lemon brownies have the consistency and texture of a fudgy brownie but made with lemon juice and lemon zest! Plus, they are topped with a sweet glaze that pairs perfectly with the lemon flavor.
Ingredients & Substitutions
It’s all about the lemon flavor in these brownies. And, I will let you know how you can add even more lemon flavor to the glaze!
Lemons: I used both lemon juice and the zest of a lemon in the brownies. Make sure you wash the lemon before zesting it. For the lemon juice, you can use fresh lemon juice or storebought juice. You could even add lemon baking chips to the batter if your store carries them.
Eggs: Make sure when adding the eggs make sure that they are at room temperature. Add the eggs one at a time, mixing well after each addition so it emulsifies with the butter.
Glaze: For the glaze, I went with a vanilla-flavored glaze, mixing confectioners’ sugar with water. However, if you crave more lemon flavor in the dessert, use lemon juice in place of water for the glaze. You can also enjoy the brownies with no glaze at all if you prefer.
Lemon Brownies vs. Lemon Bars
There is a difference between these lemon brownies and lemon bars. Lemon brownies have no base crust and the texture is dense and fudgy (like a traditional chocolate brownie). Plus, there is the optional glaze added on top of the brownies. Lemon bars, on the other hand, have a buttery crust with a lemon filling. Be sure to make both recipes if you are a fan of lemon desserts!
How to Store Lemon Brownies
Store the brownies in an airtight container, in the refrigerator, for up to five days. You could also freeze the brownies for up to three months. When ready to enjoy them, let the bars thaw in the refrigerator overnight.

Ingredients
- 1 cup (2 sticks / 227 g) unsalted butter, melted
- 1 ¾ cups (350 g) light brown sugar, packed
- 3 large eggs, room temperature
- ¼ cup (61 g) lemon juice*
- 1 teaspoon lemon zest
- 2 ½ cups (285 g) all-purpose flour
- 2 teaspoons cornstarch
- 1 teaspoon baking powder
- ½ teaspoon kosher salt
Glaze (Optional)
- 1 cup (125 g) confectioners' sugar
- 2 tablespoons lemon juice, or water for less lemon flavor
Instructions
- Preheat oven to 350°F and prepare a 9×9-inch pan by lining it with parchment paper (or lightly grease and flour). (You could use a 9×13-inch pan for more servings, but the bars will be thinner.)
- In a large bowl, combine the melted butter and brown sugar. Stir well.
- Add the eggs one at a time, stirring well after each addition.
- Stir in the lemon juice and lemon zest.
- In a separate, medium-sized bowl, whisk together the flour, cornstarch, baking powder, and salt.
- Gradually stir the flour mixture into the butter and egg mixture until completely combined.
- Spread the batter evenly into the prepared pan. Bake 35-45 minutes, or until the edges are turning golden brown. (If you are using a 9×13-inch pan, bake for 25-30 minutes.)
- Allow brownies to cool before glazing.
Glaze
- In a medium bowl, combine the confectioners' sugar and lemon juice. Whisk until smooth.
- Pour the glaze over the cooled brownies and serve.

Notes
Did you make this recipe?
Thank you for making my recipe! You took pictures, right? Well go ahead and post them on Instagram! Be sure to mention me @iambaker and use the hashtag #YouAreBaker.
I am not a baker. In fact, I hate baking.These turned out totally awesome; husband ate the entire pan. If I can do it, so can you! Thank you for the recipe.
Can you use lemon extract ipo the juice? If so how much? Thank you
Sure!
oooops, I accidentally just made them with whole wheat flower…wonder how that will turn out!!
Hi, can you use a kitchen aid mixer with a paddle instead of stirring by hand? Thank you
Sure! Just don’t over mix. 🙂
Has anyone made a 9×13 pan? If so, did you just double the recipe?
I haven’t. But if you do the brownies will be thinner and the cooking time will be less.
In my oven should I turn on the fan or NOT?
Just wanted to know if you can freeze the lemon brownies with a good result?
Since there is only 2 of us we like to freeze deserts for a later date, I don’t like baking something and then throwing most of it away
Why do you say to store browies in the refrigerator?
(Getting ready to make, they sound delicious!)
So delicious!!! They came out perfect!!!. For more of a lemony flavor I did use lemon juice in the glaze. Will definitely be making again.
Thieve turned out horrible. Despite following the recipe exactly, it had a dense, playdoh like consistency and the taste wasn’t any better.
Hi Kristin- So sorry you experienced that. Sounds like they were underbaked. Every oven is different and unfortunately, I can’t account for hot spots or different temps. However, the taste is something I can guarantee, as it was approved by over a dozen diverse taste testers. Maybe there was an ingredient off?
