The Best Lemon Bars
Growing up, my mom made the best lemon bars, so I had a few must-haves for my own version.
The perfect Lemon Bar starts with a light, sweet shortbread crust that holds up to the tangy lemon custard. The crust should balance the bright, tart filling, which needs to be smooth, creamy, and not mixed into the crust.
Despite these must-haves, I wanted a simple recipe. This version uses everyday ingredients and a blender for the filling—quick and easy!
How To Make Lemon Bars
The full recipe is below, but here are my best tips for Lemon Bars:
- Use a glass pan: Metal can change the flavor.
- Line with parchment paper: This makes it easier to lift and cut the bars.
- Use fresh lemon juice: Bottled won’t taste as good, and you’ll need fresh lemons for zest anyway.
- Chill fully: This brings out the flavor and helps the custard set.
- Don’t over-blend: Blending too long adds air bubbles.
What Are Classic Lemon Bars Made Of?
A few ingredients worth going into detail about:
- Lemon Zest: Avoid the bitter white part—only zest the yellow skin using a microplane.
- Lemon Extract: A strong lemon flavor booster, like vanilla extract. It’s found near baking spices.
- Butter: High quality butter means better flavor. Use unsalted to control the salt.
- Vanilla: Vanilla bean paste adds more flavor, but vanilla extract works too.
- Heavy Cream: This helps balance the tartness and makes the custard creamier.
How To Get More Juice From Lemons
- Microwave the lemons for 15-20 seconds.
- Knead the lemons with your hand against the counter for 20-30 seconds.
- Cut the lemon in half horizontally and juice the lemon using a juicer.
Quick Tip
How to Cut Lemon Bars Cleanly: Chill bars in the fridge until firm. Use a hot knife—run it under hot water, dry, cut, and repeat for clean slices.
How To Tell When Lemon Bars Are Done
The edges should be set, and the center should no longer jiggle when gently shaken.
How To Remove Bars From The Pan
Line the pan with parchment paper, leaving extra hanging over the sides. Use it to lift the bars out easily for cutting.
Storage
Can I Freeze Lemon Bars?
Yes! The crust and custard freeze at different speeds, so they need space to freeze properly.
- Cut the bars and place them on a lined baking sheet with space between them.
- Freeze for 2-3 hours until solid.
- Wrap each bar in plastic wrap, then store in a bag or container for up to 3 months.
For short-term storage, keep them in an airtight container in the fridge for 4-6 days.

Lemon Bars
These Lemon Bars feature a buttery shortbread crust topped with a tangy-sweet lemon filling. A dusting of powdered sugar adds the perfect finishing touch!
Equipment
- 9 x 13-inch non-metal pan
- Stand mixer or hand mixer
- Fine mesh strainer
Ingredients
- Cooking spray
- 16 tablespoons unsalted butter at room temperature, see note 1
- 2 cups granulated sugar divided
- 1 teaspoon vanilla bean paste or 1-1/2 teaspoon vanilla extract
- 2 cups + 3 tablespoons flour divided
- 1 teaspoon salt divided
- 4 to 5 lemons see note 2
- 4 large eggs
- 1/4 teaspoon lemon extract optional, see note 3
- 1/3 cup heavy cream
- Powdered sugar for topping bars
Instructions
- Line a ceramic 9×13-inch pan (don’t use a metal pan—it will make the bars taste metallic) with parchment paper, leaving an overhang for easy removal. Lightly spray the pan with cooking spray and set aside.
- In a stand mixer with a whisk attachment (or a bowl and hand mixer), beat together room temperature butter and 1/2 cup granulated sugar. Beat until smooth and creamy, about 2–4 minutes. Scrape edges of the bowl as needed. Add 3/4 teaspoon salt, vanilla bean paste, and 2 cups of flour. Beat until a thick dough forms, scraping the sides as needed. (Dough too soft? Add 1–3 additional tablespoons flour.)
- Transfer dough to prepared pan and press evenly on the bottom of the pan and a little up the sides (about 1/2-inch). Take your time, ensuring dough is in an even layer and touching every bit of the edge of the pan so the lemon filling doesn’t seep through. Preheat oven to 350°F. Place pan in the freezer 15 minutes to allow crust to firm up. After 15 minutes, remove crust and again press all the edges to the pan, making sure the seal is 100% tight. Bake 22–25 minutes or until lightly golden brown at the edges.
- Meanwhile, microwave lemons for 15 seconds. Remove, and knead against the counter with your hand. (These steps help to get your lemons super juicy.)
- Very finely zest a lemon to get 2 teaspoons lemon zest. (Be careful to avoid the white pith of the lemons—that will make your bars bitter.) Juice lemons to get 2/3 cup juice.
- In a high-powered blender, add remaining 1-1/2 cups granulated sugar and lemon zest. Pulse just to break down the zest, about 5–8 times. Do not over-blend or you’ll get powdered sugar! Add remaining 3 tablespoons flour, lemon juice, remaining 1/4 teaspoon salt, eggs, heavy cream, and lemon extract (if using). Blend for 20 seconds or until just incorporated—again, being careful to not over-blend but ensuring all ingredients are emulsified together. Use a spatula to stir the mixture and let sit until needed.
- Stir blended mixture again and pour slowly and evenly over the hot crust (right out of the oven). Bake another 20–25 minutes or until bars very slightly jiggle in the center (like firm Jell-o). Allow bars to cool at room temperature for 2 hours, then chill in the fridge until the lemon layer is firm, about 2 more hours.
- Before enjoying, sprinkle the top of the bars with powdered sugar (through a fine-mesh sieve). Pull the parchment paper overhang to remove the entire slab of bars from the pan. Run a sharp knife under hot water, dry, make one cut, and repeat until all the bars are cut out. Enjoy!

Recipe Notes
Note 1: The better the butter, the richer the flavor. I love Challenge® Butter. Choose unsalted to have perfect control over the amount of salt in the dough. Do not melt the butter so it can properly cream with the sugar.
Note 2: When zesting the lemon, avoid the white pith of the lemon—this is very bitter. Using a fine grater, zest only the very outside yellow part of the lemon for this recipe. This citrus juicer makes juicing the lemons a breeze!
Note 3: Lemon extract is a flavor enhancer (just like vanilla extract) that gives these bars a more intense citrusy lemon flavor. Lemon extract can usually be found near other baking extracts and spices in the grocery store; I recommend using a pure lemon extract.
Storage: Let leftover bars cool completely, then cover with plastic wrap and pop in the fridge for 4–6 days. To freeze them, Cut the bars out and set on a lined sheet pan, leaving room around all 4 edges. Place in freezer until frozen through (2–3 hours), then wrap each lemon bar individually with plastic wrap and store in a large bag or container and freeze for up to 3 months.

When you say mix the lemon zest with flour, do you mean the flour mixture- or the remaining 3 tbsp of flour that was separated?
Thanks in advance!
Flour mixture! 🙂 Enjoy!
Great recipe but one thing that doesnt make sense it step #3 says to bake crust then remove and set aside then down to step #7 after making the lemon topping it says explicitly to pour mixture over HOT crust right out of oven but step 3 says to remove and set aside. please fix and or clarify i just poured over hot and ignored step 3
Yes it’s supposed to be poured over the hot crust! While the crust is baking everything else should be prepared so it can be poured over. Hope that helps!
Recipe calls for white flour, would this be plain or self rising?
Plain white flour 🙂
Love that you added almond extract along with vanilla into the crust! And the recommendation to cut them cold with a hot knife… game changer!
So glad you enjoyed these; thanks!!
This dessert was a big hit. The foodies in the group raved about the hint of almond in the shortbread crust. This recipe is a keeper!
So happy to hear it; thanks so much Anne! 🙂
Is passing it through a fine mesh sieve designed to remove the zest?
And any potential flour clumps 🙂
Unfortunately the fine mesh sleeve removed my zest too!
Yes, that’s right! 🙂
Quick question:
Do you usually add your optional almond & lemon extracts? I’m happy to, but I just wanted to see what you normally prefer.
Thanks~ I’m excited to make it for a group of ladies this week!
I do! 🙂 (Why I write optional: a lot of readers don’t have the extracts and so I want this recipe to be accessible for them as well.) The bars work either way, I like them best with the extracts added. Enjoy!
I made these and they are literally the BEST lemon bars I’ve ever had!!!!!!!!!
I am soooo happy to hear this!! Thank you so much! 🙂
I don’t review recipes unless they’re exceptional, and this one absolutely was. I had been searching for days and resigned myself to either combining 5 recipes as all were missing at least one factor on their own, or making a labor-intensive stovetop lemon curd version of lemon bars requiring close to a dozen yolks for a 9” square yield. Wow. I am never going back. This was the best of all worlds and the shortbread could stand alone. And most recipes that say the dish improves with time are being generous, but these truly did! For reference, I made the recipe exactly as written with no alterations, but doubled and used a 13” x 18” half sheet pan for a crowd. Everyone agreed, these were the best. Loved the addition of cream in the filling. Thank you, thank you, thank you! I can’t wait to peruse your other recipes now.
Ahhh thank you soo much!! I am beyond glad you loved these!! <3
I made another recipe very similar to this but the other recipe had no cream in the lemon topping and 6T of flour. The batter tasted flour-y to me and the top lemon layer ended up with heavy crackling after baking – like the Mohave Desert – very ugly. Might the cream prevent the crackling I experienced? Other recipes indicated that bubbling might occur – but mine was just super heavy cracks all over the top. Thanks
