Hello again! I’m so happy to be back with another delicious spring dessert today! I have been enjoying every bit of the spring weather we’ve been having lately. We’ve been going for walks as a family every evening, and I love seeing all the fresh daffodils and tulips, and the bright spring grass. The air is warm and there’s a soft breeze blowing… it’s basically just heavenly outside! I really like making light desserts in the spring, and these delicious lemon brownies are perfect!

My husband loves all things lemon, and I think he managed to eat almost the whole pan of brownies by himself. I was able to sneak a few to taste, and they were amazing! The brownies are moist and buttery, almost like sugar cookies, with just a hint of lemon. The lemon glaze on top is tart and sweet, and makes a perfect complement to the brownies without being overpowering. I love how light they taste as well… they’re the perfect end to a spring meal!

My two little girls loved these brownies as well! They are definitely a new favorite at our house. If you love lemon like we do, you have got to give these a try!

Lemon brownies AKA lemon blondies -super soft bars topped with the most delicious lemon glaze. The perfect summer dessert.


for the brownies:

  • 1/2 cup salted butter, softened
  • 3/4 cup sugar
  • zest of 1/2 lemon
  • 2 large eggs
  • 1 Tablespoon fresh lemon juice
  • 3/4 cup flour
  • 1/2 teaspoon baking powder

for the glaze:

  • 3/4 cup powdered sugar
  • 1 1/2 Tablespoon fresh lemon juice
  • zest of 1/2 lemon


Preheat the oven to 350. Prepare an 8 x 8 pan by spraying with cooking spray or lining with foil, and set aside.
In a large bowl or the bowl of a stand mixer, beat together the butter, sugar, and lemon zest until light and fluffy. Add the eggs one at a time, mixing well after each addition, then add the lemon juice. Add the flour and baking powder, and mix until just combined. Pour the batter into the prepared pan and smooth into an even layer. Bake 20-25 minutes, or until a toothpick inserted into the brownies comes out clean. Let cool 10-15 minutes.
To make the glaze, whisk together the powdered sugar, lemon juice, and lemon zest, then pour over the brownies, spreading evenly to coat. Let cool completely before slicing and serving.

Note: if using unsalted butter, make sure to add a pinch of salt to the batter.

  1. Wow, that title scared me! I thought you were actually going to mix cocoa and lemon! These look delicious. I’m going to use different flours to make them gluten-free. I always get such a hankering for lemon anything this time of year. Thanks for the recipe. I suppose ‘Lemon Yellowies’ doesn’t have the same ring?? ;-)

  2. I’ve never tried Lemon Brownies – these I must try! Funny enough, I just posted a lemon cake recipe on Friday – I must try these though as my husband would LOVE them!

  3. My family loved the lemon brownies today. My mother in law plans 2 eat a couple with her morning coffee tomorrow.

  4. I’m dying to do this recipe this weekend since I’ll have free time between exams and All that but…

    This must be a really dumb question. But when you put 350, do you mean Celsius or Fahrenheit? Where I live we use Celsius so… I don’t really want to ruin it.

  5. Your lemon brownies sounded so yummy!
    After putting them in the oven, I noticed they did not have any baking soda/powder. They ended up like a lemon pancake. Was an ingredient missing?

  6. These brownies look amazing, I am defiantly going to try experimenting with this recipe. I have never tried a lemon brownie before. I usually stick to the usual chocolate, I tried a new spin on the original old fashioned brownie by adding a praline fudge topping to it. So yummy a must try, here’s the recipe! http://happywifehappy.life/praline-brownies/

  7. Hi!  Am making these for my book club at work and agree with Jane,  I think that baking soda is missing.  So, I added 1/2 tsp. Am  hoping for the best.  Will let you know!

  8. I followed the recipe exactly and they were delicious! I might add a little baking soda next time to see if they rise up a little, but they are very good as-is.

  9. WOW I never heard of lemon brownies before. These sound delicious. I can’t wait to make them. 

    Thanks for sharing!!

  10. In the recipe video and the instructions it calls for salt, but in the ingredients listing it says baking powder, can you tell me which one it is, I would love to try this recipe! 

  11. What kind of flour ?? Self rising or all purpose .

  12. Video shows adding salt and no baking powder, recipe says 1/2 tsp. Baking powder and no amount of salt? What is right?

    • The salt in the video is supposed to be labeled as baking soda. Sorry for the confusion! If you would like to add salt to the brownies, I would recommend adding 1/4 tsp, but it doesn’t need it. :)

  13. You omitted the quantity of salt in the list of ingredients but mention to add it in the directions.

    • This was a guest post so I am not sure. I have made the recipe with just baking soda and it turned out great! If you would like to add salt, I would recommend adding 1/4 tsp salt. :)

  14. How much salt and when do I add the baking soda? Only kidding, great easy recipe.

  15. The recipe doesn’t match the instructions.

  16. Has anyone happened to try these with gluten free flour? Thanks

  17. Can I use oil instead of butter?

  18. Hi thanks for putting this on but what is 350 in gas mark looking at ingredients it don’t say what sugar like caster granulated or what flour

  19. I love lemon, and these sound great, but since I have lines, im going to try the recipe with limes.  I’ll let you know how they turn out! :)

  20. Would I be able to substitute the butter with oil?

    • Hi! I haven’t tried substituting oil in this recipe but I think it would change the texture quite a bit. Let us know how it goes if you give it a try!

  21. These are INCREDIBLE! Perfect for potlucks and just great for summer snacking. Will definitely be putting this into my recipe box. :)

  22. I made these and the recipe came out quite tasty! Only thing is, I used a fairly large pan and so it was a little thin. I only had one size pan, I wanna say it’s like a 10 by 18. Anyway, I ran a little short on glaze (it was almost the right amount, so close!) using the amount recommended, so I’d recommend to anyone using a larger pan to make a little extra glaze.

    I put them in for 20 minutes and put a toothpick all over it, nothing came up. But then when I let them cool they were almost juicy/soggy, so I had to throw them back in the oven with the glaze on in order to try to get them harder. They were good for a first attempt (I don’t bake too much), really just making an office Friday snack so I think it’ll still work out. And it gave me an excuse to eat all the chunks that fell off while I was trying to transfer them at first :) quite delicious, just won’t win me any awards at baking competitions.

    • I’m glad you enjoyed these! Making lemon brownies or blondies are a little tricky at first to get the baking time right. Sounds like you did great!

  23. Someone is asking which is correct, the video or the recipe??? Please revies and advise.

  24. Can someone tell me if they’ve tried this with gluten free flour?? I really wanna make these for my mother in law (and myself it’s a pregnancy craving lol) but she can’t have gluten!! 

    • While I haven’t tried these with Domata flour (my favorite gluten free blend that already has xanthan gum added and you substitute amount for amount of plain flour), I have used it in all my cookie, brownie, and cake recipes with excellent results. The only fail is with angel food cake. I’m going to make these gf for my daughter.

  25. How I wish we could enjoy these Gluten Free.

  26. How much salt in the lemon brownies ?

  27. Lemon Brownies. It says to add salt but it doesn’t say to add baking powder

    • Hi Dennis! There was a mistake in the video. The word salt was supposed to say baking powder. There is no salt in the recipe, just 1/2 tsp baking powder! :)

  28. 2 things: salt is not listed in the ingredients, and the baking powder is listed in the ingredients, but not mentioned in the method. Cooking time could be a bit longer, say 30 – 35 minutes. Loved them!

    • Hi Susan! There was a mistake in the video. The word salt was supposed to say baking powder. There is no salt in the recipe, just 1/2 tsp baking powder! :) I’m glad you loved them!

  29. No reason not to use other fruits.
    Cherry, orange, lemon, lime, blueberry, grape (or boysenberry)…
    Taste the rainbow!

  30. Looking forward to future baking recipes!

  31. I made these delish lemon brownies for first time and brought them to our friends’ house other evening–Dad and the son saw lemon and said they were not fans of “lemon” but decided to try them and they ate more then others that did like lemon! these are easy to make, soft and tasty–plus lemony which I love! I will make them again soon! they were a hit!

  32. the recipe text shows ‘add flour and baking powder’, but the video never mentions baking powder and instead shows ‘add flour and SALT’.

    which is the correct recipe?

    • Hi Alan! The recipe is correct, not the video. The words on the video were supposed to say “baking powder” not salt. So the recipe has no salt and 1/2 tsp of baking powder!

  33. Hi alicia, i’m planning to make this lemon brownies right now but im confused with the recipe & the video. The video says flour & salt but on the recipe it day lemon & baking powder. Which one is correct? Would really appreciate your reply. Thank you

  34. Loved the lemon brownies!

  35. I absolutely never use white sugar. Usually substitute with coconut sugar, brown sugar or would try stevia. How much stevia should I use?

    • Hi Stacy! I don’t have very much experience with cooking with stevia so I’m not sure it would work in this recipe. It would definitely change the texture and taste.

  36. I made these last weekend and I’m going to make them again this weekend! I made them exactly as directed and was pleasantly surprised. They are so lemony without having an overwhelming bite and the sweetness is great. I may try using this recipe and use limes instead, just for a change.

  37. Please can you tell me what flour to use

  38. Can I double this recipe and use a 13×9 pan?

  39. Thank you for this recipe I used key limes and it was so very delicious, I shared your recipe and link on my Facebook page and one of my cooking groups.

  40. Want to make these tomorrow but I have no idea what cups translate to in grams?

  41. Have you or anyone making these with gluten-free flour?   I would like to use the gluten-free flour that measures cup for cup but sometimes a little more or less of an ingredient is needed. 

  42. Ginny Schneider Reply

    I made these today. THEY WERE AWESOME!

  43. Made these for my eldest son who loves anything lemon but my youngest who would eat nothing other than a vanilla cupcake, has totally fallen in love with these. Have made them three times in the last month and made two trays today as we’re having guests tomorrow. They are like little fluffy clouds!!! And oh the tang!!!

  44. Fantastic recipe! I don’t eat sweets but these looked so good. I made them for my Dad’s staff. He said they were gone in 10 minutes and all wanted the recipe!
