These Easy Lemon Blondies are made in one bowl and a bright with lemon flavor! They have the texture of your favorite classic chewy blondie and the simplicity of our one-bowl brownies!
Go open your fridge and pantry and check to see if you have the five ingredients for these blondies. You will not want to miss my fun and significantly easy twist on blondies. They are even easier than lemon pudding cookies!
These were born in my online pastry shop because I wanted sugar cookie bar that had a bright lemon flavor and the chewy texture of a blondie. Et voilà! Lemon blondies!

I’ve iced these using an easy, two ingredient glaze, but you could also use my favorite fresh strawberry glaze from this strawberry lemon pound cake or even a Lemon American Buttercream.
These Lemon Blondies are the perfect start to a bright, Summer dessert spread. Lean into the citrus vibe with some lemon bars, a lemon berry trifle, and the perfect lemon meringue cheesecake.
Lemon Blondies Ingredients:
- Butter: I use unsalted butter for baking, because you want to control the amount of salt you are adding. Every brand is different and it makes adjusting the recipe a challenge.
- Sugar: I use extra-fine sugar in baking because it dissolves faster and incorporates easier than even standard granulated sugar. Regular granulated sugar will be just fine though!
- Whole Eggs: Eggs are mission critical for emulsifying all that butter and sugar together. They also create a tiny bit of leavening.
- Lemons: The zest flavors the lemon blondies and the juice flavors the glaze!
- Salt: The kosher salt is essential in this recipe. It play a supporting roll balancing the flavors and all that sugar! Kosher salt is lass salty than table salt and a teaspoon weighs less than other finer ground varieties.
- All-Purpose Flour: I use all-purpose flour but you could also use bread flour with minimal impact.
- Confectioner’s Sugar: Also called powdered sugar or 10x because it is ground ten times finer than regular sugar.
Make the Lemon Blondies your own!
- Orange Blondies: Substitute orange zest for the lemon zest in the brownies and orange juice for 3/4 of the lemon juice in the glaze!
- Go Nuts: Add up to 2 cups of nuts like toasted walnuts, pistachios, almonds or hazelnuts after adding the flour.
- Strawberry Lemon Blondies: Fold 1 cup chopped fresh strawberries or 1 cup dehydrated strawberries into the batter after the flour. Ice with my fresh strawberry icing from this lemon pound cake instead of the lemon.
Lemon Blondies Storage:
Store in an air-tight container or wrapped in plastic wrap in the refrigerator for up to one week. Freeze for several months! The blondies freeze beautifully iced, just allow the icing ample time to set before wrapping for the refrigerator or freezer.
The lemon blondies also ship beautifully.
Lemon Blondies
Ingredients
For the Blondies:
- 1 cup butter
- 2 cups sugar
- 2 eggs
- 2 lemons zested
- ¾ teaspoon kosher salt
- 2 ¼ cups all purpose flour
For the Glaze:
- 2 cups confectioner's sugar
- ¼ cup lemon juice
Instructions
Make the Blondies:
- Preheat the oven to 325°F. Either spray a 9×13 inch pan with non-stick cooking spray or line the pan with parchment. Set aside.
- Combine the sugar and lemon zest. Rub the zest into the sugar with your fingertips to start releasing the oils. The longer it sits, the more pronounced the lemon flavor will be.
- Melt the butter in the microwave or small saucepot.
- In a large bowl whisk together the butter and sugar zest mixture.
- Whisk in the eggs until smooth and homogenous.
- Whisk or fold in the flour and salt until a smooth batter forms.
- Pour into prepared pan and bake in preheated oven for 20-25 minutes or until browned on top and gives resistance to the touch.
- Cool completely before icing.
Prepare the icing:
- In a medium bowl whisk together the confectioner’s sugar and lemon juice until the desired consistency is reached. I wanted mine to be spreadable, so I added enough lemon juice to make a paste.
- You could also use my Lemon American Buttercream, which would be delightful.
Assemble & Cut:
- Spread glaze on brownies. Allow to set for at least 30 minutes. The thicker the glaze, the longer it will take.
- Slice and serve!

WOW are these amazing. I had tried 2 other Lemon Blondie recipes (why, I don’t know. I shoulda started here first) These were a HIT! I am a Volunteer Baker at a Hospice and I try to make something new when I bake. And these are the perfect Summer bite. (I just might toss in some freeze dried raspberries next time I make them) But as they are they are light, bright have a bit of a tartness to them, not super sweet and if you keep the glaze thin you can cut back the sweetness. (If you want more a hand full of white chocolate chips might not be such a bad idea)
These will be made again!
Hi Nikki! Thank you so much for commenting and sharing your treats with the folks at Hospice! I also love your insights–that sounds delightful!
I made these for a get together and everyone loved them!! They were so straight forward to make, too – I loved everything about it! Thank you!!
Hi Aline! I’m so happy that everyone enjoyed and you had a straightforward time making them!
I was making these for a picnic with friends and they are perfect! The lemon is so bright and summery, and I am definetly making a batch just for myself!
Hi Jenn! These are so ideal for a picnic, and you should absolutely treat yourself!
I think I’ve finally found a dessert I love more than lemon pound cake! Since we have backyard hens and a lemon tree, I’ll definitely be making this one again and again. I appreciate the note about these shipping well since I love to send care packages to friends and family.
More than lemon pound cake?! Thank you for such high praise, and I hope you and your family will enjoy these in care packages down the line!
Whenever I see a lemon dessert, I have to make it! Came across your recipe and was delighted to see it. Best part of this dessert was that it was super easy to make. I am not a baker, so, I loved that you made the steps easy to follow. The blondies turned out delicious, they were a huge hit at the potluck party.
I’m so happy to hear everyone enjoyed them and it was easy for you to enjoy the process as well!
Made these with my son. Super easy recipe that turned out great!
Hi Nicky! Happy to hear it!
I’m normally not a fan of Blondies, but WOW THESE ARE SO AMAZING. This will be my new go to recipe for all those back to school pot lucks and bake sales! Thank you Chef!
