Favorite Lemon Dessert
These lemon brownies may be one of my favorite desserts ever! I love fudgy chocolate caramel brownies or rich brown butter blondies, but there’s something about a lemon brownie that’s light and fresh.
They are moist and buttery, like a soft sugar cookies recipe, with just a hint of light lemon taste like my lemon crinkle cookies. The powdered sugar glaze on top is tart and sweet and makes a perfect compliment to the brownies without being overpowering.

- Salted butter: Butter adds richness and a savory taste to brownies.
- Sugar: Sweetness is needed to balance the lemon flavors.
- Lemon: Both lemon zest and fresh lemon juice will be used in these brownies for that fresh lemon flavor.
- Eggs: This will help combine the lemon brownie batter and give it the color and flavoring.
- All-purpose flour: Thickens the batter and gives it a nice thickness when baking.
- Baking powder: Helps raise the brownies and thickens them while baking in the oven.
Substitutions and Variations
Mix it up with these lemon brownie variations!
- Other citrus. Try orange zest with orange juice or lemon zest with lime juice.
- White chocolate. If you missing the chocolate normally in brownies, add some white chocolate chips.
- Extract. Add up to a teaspoon of vanilla extract or 1/4 teaspoon of almond extract or coconut extract for a little flavor.
- Topping. Try a cream cheese glaze or even just a dusting of powdered sugar. Add a drizzle of white chocolate or top with coconut like these lemon coconut bars.
- Gluten-free. A few followers have had success substituting gluten-free flour cup-for-cup for all-purpose flour to make gluten-free.
How to Make Lemon Brownies
Lemon brownies are easy to make! Simply, mix ingredients together, bake, then make a glaze to frost the brownies.
- Mix. Using an electric mixer, beat together the butter, sugar, and zest with an electric mixer until light and fluffy. One at a time, mix in the eggs. Then add in the lemon juice. Mix in the flour and baking powder until just combined.
- Prepare. Preheat the oven to 350°F. Line an 8×8″ baking pan with parchment or foil and spray with nonstick spray. Pour the batter into the pan and smooth it out evenly.
- Combine. Whisk together the ingredients in a medium bowl. Pour on top of the brownies and spread evenly to coat.
- Bake. Bake for 20 to 25 minutes, or until a toothpick comes out clean. Let cool for about 10-15 minutes.
Lemon Glaze
The glaze is sweet with a tart lemon flavor and takes these brownies over the top! Add a little more (or less) juice or zest depending on how much citrus flavor you’d like.
- Powdered sugar: This is a sweet and powdery texture sugar that helps build up frostings and glazes.
- Fresh lemon juice: Squeeze the sliced lemon right into the glaze.
- Zest from half a lemon: The zest will add a tart but sweet texture to the glaze. This is an added touch to the top of the homemade lemon brownies.

Recipe FAQs
Here are the difference between the three and how these came to be lemon brownies (lemonies). For these to be true blondies, they would need brown sugar!
Lemon bars are made with a shortbread crust and a filling that consists of mainly of eggs, sugar and lemon juice. While usually brownies are fudgy from chocolate and butter, they can be different flavors, just like these with lemon or my strawberry brownies!
Simply cover the room temperature lemon brownies pan in an airtight container or using plastic wrap. Place in the fridge for four to five days depending on how long they still stay moist and chewy.
Yes! You can easily freeze if desired. Just wrap it in plastic wrap and then again with foil. To thaw, set out at room temperature.

Great taste! Very lemony, but consistency was that of a cake.
Thanks for the review!
If I double the recipe- you said I could use a 9×13 pan- but how long do I bake it for then? I made these before and I loved them so I want to try a bigger batch.
I would check at 20-25 minutes and then add another 5-10 minutes if the lemon brownies are not done.
Your recipe calls for half a cup of butter, but the directions say use one cup. Should I use half a cup of butter or one cup of butter.
Sorry about that! 1/2 cup butter (1 stick) is the correct amount to be used.
I made these with some slight adjustments because I wanted “brownies”. I put maybe 1/3 c of white chocolate chips (they do not taste like chocolate, more vanilla) in a microwave bowl and put the 1/2 c butter on top and microwaved until soft. I then used 1/4 tsp of baking power instead of 1/2 tsp. They are delicious! I nearly licked the bowl clean before it went into the pan!
Thanks for sharing how you made them, so glad you enjoyed them!
This was delicious! They are more cake like than brownie like which is fine with me! I made them as stated but doubled it for a 9×13. Needed about 30 minutes of baking time. Everyone loved them!
So glad you enjoyed them, thanks for the review!
Loved them! But I skipped the baking powder to make it more compact like brownies. 👍🤗
So glad it worked out for you when omitting the baking powder! Thanks for the review.
Tastes great, but as others have said I would call it a lemon cake, not a brownie. We enjoyed it, but it was not what I was expecting for a brownie.
Made this tonight and it’s definitely not a brownie, it made a fluffy lemon cake. Still very tasty but not what I was expecting.
So easy, takes no time. As a person who makes lemon meringue pie a LOT (like 9 hours) this recipe is refreshing, both mentally, and literally. The lemon takes amazing and the brownie texture is exquisite. 10/10
Glad you enjoyed them!
This is straight up cake. This is not what brownies are. It tastes great but the texture is completely different than what brownies actually are. It’s cake. :)
These lemon brownies are delicious! My husband does not have a sweet tooth but he devoured these.
Jamielyn, do you use an electric whisk to mix all the ingredients or just for the egg + butter. I felt like I over whisked mine, so curious to know.
So glad you and your husband enjoyed them! As shown in the video, I do use an electric mixer (use low speed) and only mix until combined. Thanks again for the review!
This was SO delicious, I ended up consuming it in 2 days all to myself haha. I am so glad I picked this recipe to use to make it. Making it again for sure!!
Can i use milk instead of eggs
Unfortunately, not. The eggs are needed to bind the ingredients together whereas milk would add too much liquid.
Delicious!
These are AMAZING!
I’m so happy you love3 the lemon brownies Lisa! A perfect summer treat!
