One Bowl Lemon Brownies

I am a huge lemon fan, I love the freshness and tartness, especially in desserts when its balanced with something sweet. These Lemon Brownies are so rich, fudgy and tender, and the best part is that they are bursting with lemon flavor.

If you never had Lemon Brownies you should make some as soon as possible. First, they are so incredibly easy to make and require only a handful of ingredients that you most likely already have on hand. Second, I love one-bowl desserts, and this is one of those, fewer dishes to clean, that’s always a plus! Last, but not least, they taste amazing!

Buttery, tender and rich, with the most amazing lemon flavor. Top them with a sweet and zesty lemon glaze or just dust them with confectioners sugar.

What do you need to make Lemon Glaze?

Lemon Glaze is done easily by combining lemon juice, lemon zest and confectioners sugar. You have to stir the mixture until fully combined and smooth.

How to make Lemon Zest?

Follow the easy steps below:

  • Rinse the lemon.
  • Set your tool over a cutting board. A microplane produces a very fine zest, perfect for baking and cooking. If you don’t have a microplane, use the smallest holes on an ordinary grater.
  • Grate the yellow skin of the lemon only. Grate just enough to get through the yellow skin, this way you can avoid the bitter white pith underneath.
  • Rotate the lemon and repeat. Once the white pith is exposed, rotate the lemon and zest the next strip of peel. Repeat until most of the peel is removed, or until you have enough zest for your recipe.

Can you freeze the Lemon Brownie Bars?

Cool the Lemon Brownies completely and do not glaze them. Fully wrap the bars in plastic wrap, tightly. After that wrap in aluminum foil or place in freezer bags. Freeze for up to 3 months. Defrost before serving.

Ingredients
 
 

Lemon Brownies:

  • 1 cup all-purpose flour
  • 1 cup white granulated sugar
  • ½ teaspoon kosher salt
  • 12 tablespoons (3/4 cup) unsalted butter softened to room temperature
  • 3 large eggs room temperature
  • 2 lemons zested and juiced

Lemon Glaze:

  • 1 cup confectioners sugar
  • 2-3 tablespoons freshly squeezed lemon juice
  • 1 tablespoon freshly grated lemon zest optional

Instructions
 

  • Preheat oven to 350 degrees F.
  • Line a 9x9-inches baking dish with parchment paper and grease it with baking spray or butter, set aside.

Lemon Brownies:

  • In a large bowl, using an electric mixer beat together: flour, sugar and butter until creamy.
  • Add salt, eggs, lemon juice and lemon zest to the flour mix. Beat on medium speed until smooth, about 3 minutes. Stop once to scrape the sides and bottom of the bowl with a spatula. Pour batter into the prepared baking dish.
  • Bake in the preheated oven for about 25 minutes, start checking after 20 minutes of baking. A toothpick inserted in the center should come out clean and the sides of the cake will start to get golden brown, while the center will be settled.
  • Remove from oven and cool in the baking dish for 10 minutes, after that transfer the cake to a cooling rack and continue cooling.

Lemon Glaze:

  • Add all the ingredients to a medium bowl and stir to combine until smooth, with no lumps. If the mixture is too thin, add more confectioners sugar, 1/4 cup at a time. If the mixture is too thick, add more lemon juice, 1 tablespoon at a time.
  • Spread the glaze over the cooled brownies. Let it settle.
  • Slice into bars and serve.
  • Store in the fridge in an airtight container or wrapped in plastic wrap for up to 4 days.

  1. Lemon desserts are some of the best! The sweet and tart flavors work so well together. I’ve never had lemon brownies, but after seeing your recipe I HAVE to try them!! Brownies make me think of fudgy and chocolaty, but these look completely different. I could totally go for a batch of these! They look absolutely amazing!5 stars

  2. I have had many different Lemon desserts in my lifetime but I have never heard of a lemon brownie. They look delicious and that is the first thing that gets me. When I see something so pretty I assume it will taste as good as it looks. I am sure this would be a hit at my house!

  3. What delicious witchcraft is this? Who knew that brownies didn’t have to be… well, brown? You’re a genius, lemon brownies sound absolutely divine.5 stars

  4. A quick and easy to make. I may add more lemon juice next time as these had just a subtle lemony flavor. Great texture…just like a brownie! Definitely make again.

  5. Great variation on a classic Brownie!!
    I love the pretty yellow so fresh ! 
    I would definitely give this recipe a 10 star!!
    Easy to assemble and everyone thought they were amazing 5 stars

  6. I made these today and there were absolutely delish!! i was wondering if i can double the recipe? i wanna make a bigger batch..
    Thanks

    1. Probably a little longer, you will have to monitor and keep an eye on it. But I would say give it a few extra minutes.

  7. Just tried this and it turned out great!! I will say mine probably needed a little more time in the oven, I did 25 mins and the bottom was still a bit gooey (not necessarily a bad thing though). Could be because I used bob’s red mill gluten free baking flour instead of wheat flour, which I think is also why it had a very slight mochi-like texture that I actually really liked. Tart but not too tart with some powdered sugar on top!5 stars

  8. Great recipe!! Easy instructions! I’m still learning to bake. However, these made me look like a pro! Super delicious. Thank you.

  9. I would like to make these but I only have an 8×8 baking dish, would this be okay? I don’t think my 9×13 dish would work. Any suggestions?
    Thank you!

  10. I want to make these today but only have an 8×8 or 9×13 baking dish. Which would be best to use?
    Thank you!

  11. My lemons are juiced & tested. So when you say 2 lemons juiced, how much juice is that, please?

  12. So darn delicious! I converted this to gluten free and it turned out so good! The kids said they were better than sour patch candy which is a good thing because…..where did they get candy?

  13. the lemons india are quite small so could you please specify how much juice and zest should be used in this recipe

  14. Turned this into a gluten free cake

    I made this gluten free and it was a hit with everyone, GF and not. Next time will make it with regular flour though. I dont like texture of GF flour so added nuts…see below. I made some modifications.

    For the brownies:
    I cut sugar back to 2/3 c
    Added 1/4 t. Ground cinnamon
    1 t vanilla extract
    1/2 c finely chopped pecans

    I baked it in a long 11×17 inch glass baking dish ( added extra half cup flour and 2 T sugar and one more egg due to size of pan. The brownies were about 1 inch thick)

    When partially cooled I cut the brownies into two large equal pieces.

    Glaze

    Made quite thin and runny glaze with lemon juice and lots of zest

    Spread a thin layer of glaze on one half, let it run over the sides, while still sort of warm
    Sprinkled with finely chopped pecans
    Placed the second half of brownies on top and repeated

    Now I had a two layer lemon cake. Served with a mix of fresh berries and vanilla yoghurt.

    Went out for the evening. By the time I returned the cake was gone!!5 stars

  15. These are really lemony. I made exactly as recipe. Forgot to add the salt but used 1/4 tsp regular salt & added once already in oven. Added some chopped pecans in mix & icing got thick with 2 tbsp lemon juice.. but great to spread & topped icing with finely chopped pecans. Ate a piece warm but chilling them cause they were very soft! If you eat 2, 12 fit perfectly in a flat Tupperware so you don’t have to stack them & are air tight. Thank you! Yummy5 stars
