The Best Lemon Squares
These luscious Brown Butter Frosted Lemon Squares are the perfect lemon treat!! They’re soft, chewy, and practically melt in your mouth. A decadent brown butter lemon shortbread is topped with a sweet lemon glaze. I made these for a party and they disappeared off the plate!
They’re so easy to make. All you need are 5 ingredients.
How to Make Brown Butter Frosted Lemon Squares
Start by melting the butter in a large saucepan. Use a bigger pan than you think you’ll need, because the butter rises when it’s browning.
While the butter is melting, whisk occasionally. When it starts to foam, like above, whisk continuously until the butter turns brown and fragrant.
When the butter is brown, like above, remove immediately to a large bowl.
Let the butter cool, then whisk in 2 tablespoons of lemon juice.
Add the sugar, flour, and salt to the butter and beat with a mixer on low speed until just combined. Press into the bottom of an 8×8 pan. I like to line my pan with foil to make it easier to remove after baking. Here’s my trick that makes lining a pan with foil SO much easier.
While the lemony shortbread is baking, let’s whisk up the sweet lemon glaze. Take 1 cup of powdered sugar, stir in 1 tablespoon melted butter, add the zest of 1 lemon, then squeeze in just enough lemon juice to make a pourable glaze, about 1.5-2 tablespoons. I could seriously eat this glaze just by itself!
When the pan is completely cool, pour the frosting over the shortbread. Allow the glaze to set before cutting into squares. You can place the pan in the refrigerator to speed up the process.
I am still dreaming about these Brown Butter Frosted Lemon Squares!! I wish I had one in front of me right now! Hope you enjoy!! :)

Instructions
- Preheat oven to 350 degrees F. Line an 8×8 baking dish with foil.

I had bookmarked this recipe a couple years ago when I made your peanut butter pie recipe (which is awesome by the way!). I was going through my bookmarks this evening and came across these brown butter lemon squares and decided on a whim to make them, and I’m so glad I did! They are incredible!!! Thank you so much for sharing, this will definitely be a repeat in our home!
These were absolutely to die for! Thanks for sharing them with us!!!!
Amazing. I’m trying these and wanna know any substitute for powdered sugar. Can I use granulated? And can I use some other fruits juice instead of lemon? Any suggestions?
My mouth is unhappy because one of these bars is not in it right now. I am a sucker for anything brown butter, this sounds like a wonderful and creative summery dessert!
I made these last night, but the amount of butter seems like too much, or else there’s not enough flour! The texture was good, the glaze was delish, but the shortbread was too buttery. Maybe next time I’ll use the standard shortbread ratios. :)
These are SO good! I don’t even make the glaze because the squares are amazing by themselves. :)
Love the brown butter/lemon combo! These look amazing!
Fantastic work Kevin and Amanda! We loved your style. Great photography and presentation guys! Bookmarked! Keep up the good work,
Panos and Mirella
