Ingredients for lemon blondies

Ingredients for this lemon brownie recipe. 

Here are the ingredients you will need to make this. Make sure to scroll down to the recipe card for the full detailed ingredient measurements. 

  • Butter- You can use salted or unsalted butter. 
  • Granulated & Powdered sugar – This recipe uses a mixture of sugars to get the bar texture to be just right. Make sure to use powdered sugar that doesn’t have corn starch to avoid that bad aftertaste. 
  • Eggs– The eggs are the binding agent of this recipe. 
  • Vanilla extract– The vanilla extract adds an extra depth of flavor to these blondies. 
  • Lemon extract– Adding lemon extract allows us to increase the lemon flavors in our bars. 
  • Lemon juice & Lemon zest– The lemon juice and lemon zest will both be added to the brownie layer to kick up the lemon flavor up a notch. That real lemon flavor is unlike any other! We will use both for the brownie batter as well as for the delicious lemon glaze
  • Flour– Use AP flour for this recipe. 
  • Salt– Always add a little salt to your baked goods to balance out the sweetness of your recipe.

The best way to measure your ingredients is to go with the weight measurements that I have on the recipe card below. That way you get the best out of this simple recipe.  

Why is there no baking soda or baking powder in these lemon blondies?

This recipe doesn’t use any leavening agents because we want our bars to be extra moist, thick, and fudgy. If you’re more of a cakey brownie/blondie type of person you can add 1/4 tsp of baking powder.

How to make lemon blondies at home?

This is how you can make these blondies at home. Make sure to scroll down to the recipe card for the full detailed instructions!

  3. Sift in the flour and salt and mix to combine. 
  4. Pour in an 8×8 baking pan and bake. 
  5. Let the bars cool down completely before topping them with the glaze. 
  6. Set your lemon brownies aside so that the glaze can fully set before slicing into them and enjoying. 

Frequently asked questions – FAQ

How to store lemon brownies?

These lemon brownies can be stored in an airtight container at room temperature for up to 3 days. 

You can also keep them in the fridge for a bit longer. 

Freezing instructions

To freeze these, wrap the whole thing before slicing in plastic wrap then place it in an airtight plastic container and freeze for up to 2 months. 

If at all possible, don’t glaze these lemon blondies until you thaw them so that the glaze doesn’t get too wet when the bars are thawing. If you can’t do that, it’s all good the brownies will still taste super good but the glaze might be more on the wet side. 

Thaw in the fridge overnight or on the countertop for a few hours. 

Overhead shot of glazed lemon blondies

Can I double this lemon blondies recipe? 

Yes! All you have to do is hit the x2 in the recipe card to get the right measurements and bake it in a 9×13′ pan! Just know that you will have to bake these blondies for a tad bit longer. 

Can these be made gluten-free?

Yes! You can use Bob’s Red Mill 1:1 GF flour or even King Arthur flour 1:1 GF flour. 

Are these the same as traditional lemon bars?

No traditional lemon bars have a shortbread crust and a lemon custard on top while this one yields something more similar to a fudgy chocolate brownie in texture but uses fresh lemon flavor and no chocolate in it. 

Can I use bottled lemon juice?

Fresh lemon zest and juice are a must in this recipe! Since it is the main flavor profile in both the blondie as well as the simple lemon glaze, using high quality ingredients is a must. 

Using bottled lemon juice might give these an odd aftertaste. 

The best summer dessert

Can these lemon brownies be made ahead of time? 

Yes! Bake them, wrap them tightly in plastic wrap, and store them in the fridge for up to 7 days. Once you’re ready to serve them, top them with the glaze, let it set, slice, and serve. 

Can these citrus brownies be made with orange or lime instead of lemon? 

Absolutely! You can play around with your favorite citrus fruit and create your perfect dessert. It might be a bit harder to find extracts and flavorings of other citrus fruits but nothing you can’t find online! 

How can I get clean slices like the ones in the photos?

Allowing these delicious lemon brownies to cool down fully and using a sharp knife is key to ensuring that you get beautiful and sharp slices every time. 

It is also a good idea to clean your knife after each slice to ensure that the residual doesn’t get stuck on top of the bars

    Make these! They are delicious, and the texture makes these a very enjoyable alternative to traditional brownies or blondies. I followed the recipe exactly, but made a double batch in a 9×13 pan because why would you ever want less than a 9×13 pan of delicious lemony goodness?

    1. Chahinez says:

      I know right! I’m glad you enjoyed the recipe 😁

        Delish!! My daughter recommended and one of my favorites. I added about 1/4 C softened cream cheese to icing to get away from the cornstarch taste in powdered sugar. subbed extra lemon juice for lemon extract

      2. Chahinez says:

        That was a good idea! I’m glad you enjoyed it!

    2. Claire says:

      How many lemons does this recipe use?

      1. Chahinez says:

        It uses about 1-2 large lemons!

      2. Matthew Munoz says:

        I used a glass 8×8 and 16-17 minutes was not even close to enough time. I’m not a big baker so I don’t know what to do besides bake them for longer. Only
        Issue is the parchment started to smoke,
        Which is obviously not good 🤷🏻‍♂️

      3. Chahinez says:

        I’m sorry to hear that 🙁 metal pans heat up faster than glass pans so that might be why.

    3. Alex says:

      Hello,

      What is the corrected cooking time if I bake these in a 9 x 13 inch baking pan?

  2. Becky says:

    I made these for a family party and have now made them for 2 more parties! Everyone loves them, they’re a huge hit. And the best part, I usually have all the ingredients on hand! Except for lemon extract, but I just add a little more fresh lemon juice 🙂

    1. Chahinez says:

      OMG that’s awesome! I’m glad the recipe is coming in handy for you 🙂

  3. Ricarda says:

    marvelous. so quick and easy to make and sooooo tasty!

    1. Chahinez says:

      Thank you!

  4. untgregory says:

    I just pulled my first attempt out of the oven. I messed up, and forgot the quarter cup of powdered sugar in the cake. Maybe it will just be slightly less sweet. My only issue with this recipe, is how the bottom part is written. It is a bit confusing because it sounds like we are to add everything together. Then all the sudden we’re folding in the dry and wet ingredients. Because I was reading it straight from the website, I just thought it all went in at once, until I read that part. Maybe add a quote in a separate bowl, mix the eggs…”

  5. Jo says:

    Used 3/4 cup sugar, 3 tables spoons of lemon juice, and 1 tablespoons of dried orange peel… added cranberries and walnuts… so good!!!! Husband was guinea pig! He loved them!

    1. Chahinez says:

      I love that!

  6. Erika says:

    I made this a few times and it is spectacular !!! Easy and full of flavor. Sending a tip to everyone. An easy way to zest a lemon is freeze it. Zest the entire lemon with little effort. I then let it thaw to get the juice out.

    1. Chahinez says:

      That’s awesome!

  7. Tanya says:

    Perfection! Bright, not too sweet, and have a soft, brownie-like texture. I didn’t have lemon extract and used almond instead — worked very well.

    1. Chahinez says:

      Ooo nice! I’m glad it worked out ☺

  8. Lisa says:

    Trying to figure out what I did wrong? My mixture looked curdled prior to the flour/salt step. Was it supposed to look like that? In oven now praying it comes out and didn’t waste all those ingredients 🤞🏻

    1. Chahinez says:

      Hi Lisa! What did you use to measure the ingredients? (measuring cups or kitchen scale), I would highly recommend you use a kitchen scale 🙂

      1. untgregory says:

        The entire recipe is written using cups, tablespoons, etc.

      2. Amber says:

        Mine also came out looking curdled I just mixed it in anyway and it looked alright. Why would it look curdled? what did I do wrong? I’m a beginner please help. (I used cups)

      3. Chahinez says:

        I’m guessing it’s you might’ve combined cold ingredients with the hot butter. You said it curdled and then you mixed it in? So how was the final product after it baked?

    2. Tina says:

      Mine was curdled as well. Did it turn out ok after baking?

    3. Shirley Bonilla says:

      Hi, Lisa:
      I’m guessing the eggs cooked a little in the warm butter.

  9. Kelly says:

    these are so delicious! my husband is a lemon bar fan, and now prefers these. they seem to get better every day. thank you!

    1. Chahinez says:

      You’re welcome 🙂

      1. J Cook says:

        4 stars
        I thought the batter tasted too sweet, so I added all the leftover lemon juice for a total lemon juice content of 1.5 lemons.
        They turned out beautiful with the tempered down sweetness an were very much enjoyed. But everyone to their own taste I suppose. I noticed this is an American recipe and they love their sugar.

      2. Chahinez says:

        Thanks for trying out the recipe!

    Every single recipe of yours that I’ve tried is phenomenal!! This one did not disappoint either, so perfectly lemony and a satisfying summer treat! My father-in-law loves lemon flavored treats because he can’t taste a lot of things, so I made them for Father’s Day and he absolutely loved them!! Thank you for providing another winner of a dessert.

    1. Chahinez says:

      Thank you and I’m glad y’all enjoyed the recipe!
