What Do Lemon Bars Taste Like?

In my mind, the perfect Lemon Bar starts with a light, sweet crust that holds up well with the lemony topping. The shortbread should be sweet enough to balance the tangy, bright lemon custard. The custard needs to be just right — tart and sweet with a smooth, creamy texture.

The crust and custard should be clearly separate, not mixed together.

Despite these flavor and texture requirements, I don’t want the bars to be hard to make. This Lemon Bar recipe uses simple, everyday ingredients. No complex steps either — we use a blender for the filling to make it quick and easy.

How To Make Lemon Bars

The full recipe is below, but here are my top tips for tasty Lemon Bars:

  • Use a glass pan. A metal pan can transfer a metallic taste to the bars.
  • Line the pan with parchment paper. This will make it much easier to get the bars out and slice them into clean bars.
  • Use fresh lemon juice. The bottled lemon juice won’t cut it on these, flavor-wise. Since this lemon bar recipe calls for actual lemon zest, you’ll need real lemons anyways.
  • Don’t rush chilling. The flavors meld together really well in the fridge, making the bars that much more flavorful and tangy. The time in the fridge also allows time for the custard to firm and fully set up, so leave ample time for enough chilling.
  • Do not over-blend. To keep the filling as easy as possible to make, we blend all the ingredients together. However, you do not want to blend for an extended time. This will cause too many air bubbles to form.

What Are Classic Lemon Bars Made Of?

A few ingredients worth going into detail about: 

  • Lemon zest. When zesting the lemon, avoid the white pith of the lemon — this is very bitter. Using a microplane (like this one), zest only the very outside yellow part of the lemon for this recipe. 
  • Lemon extract. Not to be confused with lemon juice, 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.
  • Butter: The better the butter, the richer the flavor of the shortbread. Choose unsalted to have perfect control over the amount of salt in the dough.
  • Vanilla: I love adding vanilla bean paste to add even more flavor and nuance to the crust. That said, a pure vanilla extract also works well.
  • Heavy cream: Perhaps a unique ingredient for Lemon Bars, but I swear by this addition! It helps balance the tartness and adds a nice creaminess to the custard.

How To Get More Juice From Lemons

  • Microwave the lemons for 15-20 seconds.
  • Knead the lemons with your hand against the counter for 20-3o seconds.
  • Cut the lemon in half horizontally and juice the lemon using a juicer.

Quick Tip

Storage

Can I Freeze Homemade Lemon Bars?

Yes! However, because the shortbread crust and the lemon custard freeze at different speeds, they need plenty of space to freeze.

  • Cut the bars out and set them on a lined sheet pan, leaving room around all four edges.
  • Place in the freezer until frozen through (2-3 hours).
  • Once frozen through, wrap each lemon bar individually with plastic wrap and store them in a large bag or container and freeze for up to 3 months.

These bars can be stored in an airtight container in the refrigerator for 4-6 days.

Lemon Bars FAQs

How do you cut Lemon Bars cleanly?

  • Once the Lemon Bars have cooled completely, place them in the fridge.
  • Leave in the fridge until cold and firmly set.
  • Cut them while they are cold out of the fridge, using a hot knife.
  • Run the knife under hot water, dry, make one cut, and repeat this process until all the bars are cut out.

How do you tell if your Lemon Bars are done?

The best way to check for doneness is by jiggling the pan. When you jiggle the pan, the top lemon custard should wiggle like firm Jell-O.

Looser wiggle? Not quite done. No wiggle? Bars may be overcooked.

How do you remove the bars from pans?

Before making the bars, line the pan with parchment paper, leaving some as an overhang. You can then pull this overhang to remove the entire slab of bars from the pan to a cutting board or surface.

Why are my Lemon Bars white on top?

If your bars have a white, foamy layer on top, it’s just air bubbles from the eggs—totally normal. Once you add powdered sugar, no one will notice.

Why are my Lemon Bars runny?

This is most likely from an under-baked crust or under-baked bars as a whole.

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!
Prep Time: 30 minutes
Cook Time: 45 minutes
Chilling Time: 4 hours
Total Time: 5 hours 15 minutes
Servings: 24 bars (9x13-inch pan)

Equipment

  • 9 x 13-inch non-metal pan
  • Parchment paper
  • stand mixer or hand mixer
  • Blender
  • 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 9x13-inch pan (donโ€™t use a metal panโ€”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 2โ€“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 1โ€“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 doesnโ€™t seep through. Preheat oven to 350ยฐF. 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 22โ€“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 lemonsโ€”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 5โ€“8 times. Do not over-blend or youโ€™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 incorporatedโ€”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 20โ€“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 Challengeยฎ 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 lemonโ€”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 extractย 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 4โ€“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 (2โ€“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.

    I made these for an extended family dinner, and they were very good. My only comment is that step 2 has adding the liquid vanilla to some pretty dry stuff, and I ended up with vanilla-soaked blobs at the end of step 2. It worked out okay, but I’d recommend mixing the vanilla with the butter then adding the sugar and flour. Thank you for the recipe!

    1. chelseamessyapron says:

      So glad you enjoyed these! Thanks for the comment and your feedback Amy ๐Ÿ™‚

  2. James Sklar says:

    I’m going to try these with coconut oil rather than butter and stevia…

    1. Shelby says:

      These look amazing! Do you think I could sub half and half for the heavy cream?

      1. chelseamessyapron says:

        Thanks Shelby! Unfortunately I don’t think half and half would work on these :/

    Chelsea I made these today using a metal pan. They still came out perfect. Did not change to time but kept peeking in the oven window to make sure they were not overcooking. Delicious!

  5. Janet says:

    Can I use a metal pan and if so should I still line it with foil?
    Thanks for you help.

    1. chelseamessyapron says:

      I would definitely line the metal pan with foil and the cook time will likely be a bit different ๐Ÿ™‚

    I’ve been trying it yesterday, and it’s delicious, but so incredibly sweet! Like – one bite and I have diabetes ๐Ÿ˜€ . It’s interesting, I’m a huge fan of you american foodporn bloggers (like you, cremedelacrumb, Pinch of Yum etc.) and I L-O-V-E your recipes, you make my life so much easier! You’re doing a wonderful job, BUT, each time I bake something according to american recipe, no one want to eat it, saying it’s too sweet. You must be used to completely different type of cakes.
    So yeah, hello from Europe ๐Ÿ˜€

    1. chelseamessyapron says:

      Hey Jane! So great to hear from you! Thank you so much for your kind compliments ๐Ÿ™‚ And yes! Desserts are definitely sweeter in the states ๐Ÿ™‚ My husband lived in England for 2 years and has told me how much sweeter our treats are!

    Aside from the fact that these lemon bars are making my mouth water – you’re killing me with those colors! That blue makes these lemon bars pop that much more. Too bad they can’t just pop right onto my table ๐Ÿ˜‰
