About the Recipe
Just like the Chocolate Covered Peanut Butter Eggs I've shared with you, this Super Easy Lemon Bar recipe is another family favorite because it comes slightly adapted from the recipe box of my late Grammy!
If you're ever craving a lip-smackingly good dessert, this tart and tangy treat is the best lemon bars recipe you'll ever make!
Key Ingredients Needed
To make these lemon bars from scratch, you will need only these six ingredients:
- All-Purpose Flour. Needed for both the shortbread crust and the lemon curd filling. for the filling, I recommend sifting the flour to avoid any potential clumps.
- Unsalted Butter. This is only needed for the shortbread crust. Make sure it's at room temperature.
- Powdered Sugar. Mainly needed for the shortbread crust layer, but you can also use this as a dusting over the lemon bars—after they have cooled and chilled!
- Granulated Sugar. You'll only need this for the lemon curd filling. You can use regular white granulated sugar or organic pure cane sugar.
- Lemons. You'll need about three medium-sized lemons for the lemon juice and zest.
- Eggs. It helps to bring that beautiful lemon filling together!
How to Make Super Easy Lemon Bars from Scratch
This is a pretty straightforward, easy lemon bar recipe to prep and takes roughly a total of 40-48 minutes to bake. The lemon bars do require some time for chilling, however.
Shortbread Crust
Prepare the shortbread crust. This buttery shortbread crust comes together very quickly with the help of using either a food processor, stand mixer, or hand-held mixer. I prefer the food processor, but any of these will get the job done.
See my general prep tips below for adding a parchment paper sleeve before adding the shortbread dough to the pan!
Press the shortbread crust into the bottom of the baking pan. You can level and flatten the top of the crust using a spatula or the bottom of a measuring cup.
Chill the crust. Place the prepared shortbread crust into the refrigerator or freezer for about 10-15 minutes. I prefer the freezer, but if using a glass pan, I would stick to the refrigerator, or you can skip it altogether.
Bake the crust. Bake for 12-15 minutes at 350ºF or until you get a light golden brown top. Let it sit at room temperature to cool slightly while you make the lemon curd filling.
It does not need to be cooled completely before adding the lemon curd filling.
Lemon Curd Filling
Prep your ingredients before starting. This includes prepping the lemon juice and lemon zest, and I suggest sifting the all-purpose flour. It's a small amount to sift, but it keeps any lumps out.
Mix the ingredients together. Place all of the ingredients into the mixing bowl and whisk on medium speed until it's well blended. That's it!
Pour, then bake. Pour the lemon curd filling into the slightly cooled shortbread crust and bake for an additional 25-30 minutes at 350ºF. Be careful not to overbake the lemon bars. You still want the center to have some jiggle to it when it comes out.
Cool to room temperature, then chill. Cooling the lemon bars to room temperature after they're done baking can take up to approximately 2 hours. After cooling to room temperature, I highly suggest chilling the lemon bars (covered) for a minimum of 1 hour in the refrigerator.
This allows the lemon filling to become firm. It makes for an easier, less messy time of cutting them as well.
Plus, if I'm being honest, they just taste really good chilled!
Recommended Baking Tools
For these foolproof lemon bars, you'll need the following baking tools:
- 8 inch Square Baking Pan
- Hand Mixer or Stand Mixer
- Spatula
- Flour-Based Baking Spray. Baker's Joy is my favorite!
- Parchment Paper. Optional to use as a sleeve for easier removal and cutting of the lemon bars.
- Citrus Juicer
- Fine Grater
- Sifter. For the all-purpose flour in the lemon curd filling.
Helpful Tips for Making the Best Lemon Bars
- I used an 8-inch square baking pan for this lemon bars recipe, but you can also use a 9-inch square pan. For the latter size, adjust your recommended baking times to 20-25 minutes at 350ºF.
- Chilling the lemon bars gives them a nice firm texture. It helps make them easier to cut and taste good chilled! A minimum chill time of 1 hour is needed, but I highly recommend chilling them for longer!
- You can place a parchment paper sling into the bottom of your baking pan for easier cutting. To prevent the sides from collapsing into the lemon bars during baking, you can use metal binder clips!
- I used this KitchenAid lemon juicer for the lemon juice. It's inexpensive and does a good job of separating the seeds and pulp from the juice. It also has a measuring cup on the side!
- To get the lemon zest, I used my Microplane grater.
- Make sure to sift the all-purpose flour. If not, it may not fully mix with the other ingredients, leaving little lumps.
How to Freeze Your Lemon Bars
Make the lemon bars following the recipe instructions, then cool them completely. Skip adding the powdered sugar.
Once cooled, cut them into squares and freeze them until solid. Wrap each bar 2-3 times in plastic wrap and place it back into the freezer in a freezer bag or tightly sealed container. They can also be frozen whole and wrapped in plastic wrap and aluminum foil. Lemon bars will last in the freezer for up to 3 months.
To defrost, place them in the refrigerator up to 24 hours in advance. If frozen whole cut them into squares. You can sprinkle them with powdered sugar before serving.
Lemon Bars FAQs
You will need an 8-inch square baking pan.
Overbaking the lemon bars can cause the top to form this thin crust. You can try to pick it off or do what I've done and simply dust some powdered sugar over the top. They'll still be good!
No, it's not required, but it does help to firm up the butter a little before baking. If you're using a glass baking dish, I don't recommend chilling it before baking.

📖 Recipe
Super Easy Lemon Bars
Author:Ingredients
shortbread crust
- ½ cup Unsalted Butter (room temperature)
- 1 cup All-Purpose Flour
- ¼ cup Powdered Sugar
lemon curd filling
- ½ cup Lemon Juice (2-3 lemons)
- 1 tablespoon Lemon Zest (finely grated)
- 3 Large Eggs (room temperature)
- 1 ½ cups Granulated Sugar
- ½ cup All-Purpose Flour (sifted)
- Powdered Sugar (for dusting)
Instructions
shortbread crust
- Lightly spray an 8” x 8” baking pan with a flour-based baking spray. Set to the side. If you'd like, you can spray the pan, then place a parchment paper sling into the pan which can help make for easier cutting later. To prevent the sides from collapsing into the bars during baking, you can place a binder clips on top of the paper.
- Using a hand mixer or a stand mixer fitted with a paddle attachment, beat together the unsalted butter, all-purpose flour, and powdered sugar until the shortbread bottom layer forms. It will resemble light yellow loose crumbs. Pat the shortbread layer into the bottom of the prepared 8″ x 8″ pan. Then place in the freezer or refrigerator for about 10-15 minutes to chill. You can skip the chilling if you're using a glass baking dish.½ cup Unsalted Butter, 1 cup All-Purpose Flour, ¼ cup Powdered Sugar
- While the shortbread layer chills, adjust the oven rack to the 2nd level position (just above center) and preheat the oven to 350ºF.
- Place the pan in the oven and bake for 15-18 minutes at 350ºF or until it's light golden brown.
- Remove from the oven and allow to cool slightly while you prepare the lemon curd filling. You can choose to leave the oven on, or you can turn it off while you make the lemon curd filling. If you turn it off, remember to preheat it again to 350ºF.
lemon curd filling
- Grate a lemon with a fine grater, adding the zest to a small bowl. Then cut each lemon in half and with a lemon juicer, squeeze out the lemon juice from each lemon. Sift the all-purpose flour into a small bowl.
- Using a hand mixer or a stand mixer fitted with a whisk attachment, mix together the lemon juice, lemon zest, eggs, granulated sugar, and all-purpose flour on medium-high speed until well blended.½ cup Lemon Juice, 1 tablespoon Lemon Zest, 3 Large Eggs, 1 ½ cups Granulated Sugar, ½ cup All-Purpose Flour
- Pour the lemon curd filling into the slightly cooled crust, then place back into the oven to bake for 25-30 minutes at 350ºF or until the top is almost set with the center jiggling a little. I recommend checking on them at the earliest recommended baking time to start.Note: Leaving them in too long can cause a thin crust to form over the top. The lemon bars are still good though if this happens!
- Remove from the oven and allow lemon bars to cool completely. Then cover and place into the refrigerator to chill and set for a minimum of 1 hour (overnight is my preference). When ready to serve, dust with powdered sugar and cut using a well-sharpened knife.Powdered Sugar
- Keep lemon bars stored in an airtight container in the refrigerator for up to 5 days.

Recipe Notes
- The 48-minute cook time noted above combines the longest baking time for both the shortbread crust (18 minutes) and the final baking time for both layers (30 minutes).
- If you'd like, you can spray the pan, then place a parchment paper sling into the pan, which can help make for easier cutting later. To prevent the sides from collapsing into the bars during baking, you can place a small dab of the lemon filling in between the parchment paper and baking tin, or you can use metal (not plastic) binder clips.
- You may notice a small amount of the lemon filling fall behind or slightly under the parchment paper sling (if you use one) during baking. This is okay—it happens to me when I make them sometimes. Please note, this does not mean the lemon filling moves entirely underneath the crust.
- Overbaking the lemon bars for too long can cause a thin crust to form over the top. You can try to pick it off, or do what I've done and dust on some powdered sugar because they're still good!
- To prevent the powdered sugar topping from melting, you can use King Arthur's non-melting powdered sugar. I love it for desserts like this and my dark chocolate crinkle cookies!

Kathryn says
By far the best lemon bars I’ve ever made and I’ve tried many recipes.
Jennifer says
Thank you so much, Kathryn!
Mimi says
What size pan should be used for doubling or tripling the recipe?
Jennifer says
You could use a 9 x 13 pan if doubling the lemon bars recipe. For tripling it, I would guess a 9 x 13 and an 8 inch square baking tin.
Tara says
Made these for Easter this morning and they turned out wonderful! Thank you for sharing!
Jacqueline Carrano says
Mine taste a tad bit eggy, any suggestions? Thanks
Jennifer says
Hi! With an eggy taste, it's more than likely the lemon bars were over baked. You want to make sure to bake them until they're almost set with the center jiggling a little.
Kate H. says
Hey there! Thank you for this great recipe, I made it last week to take as the dessert to meal for a friend that had a new baby. I noticed in the notes you mentioned that the filling and crust could sometimes switch places, which mine did. Nothing disastrous, but it did make it harder to cut, and I wondered, is there a way to prevent this from happening? I did use parchment paper, the time that the crust and filling switched places, but wondered if it was anything I could do to keep the crust at the bottom next time?
Jennifer says
Hi Kate! I've never had the filling and crust switch places, so I can't speak to that result, I'm sorry! In my notes, what I meant was the lemon filling can sometimes sneak down behind the parchment paper sling. But not where it would cause the crust and filling to reverse during baking.
Angela says
My crust seemed to float to the top and switch places as you described. I followed the directions and used the parchment. I’ve only made it this one time so haven’t played with the recipe to see what might fix the issue.
Tina L. says
So easy to make and delicious! They’ve come out absolutely perfect every time we make them.
Jennifer says
That makes me so happy to hear, Tina, thank you!
Lauren says
My crust didn't bead up like it was supposed to. How does those three ingredients turn into "yellow loose crumbs"?
Jennifer says
Hi Lauren! If your butter was really soft you could have ended up with a more well formed dough that kind of looks like bigger lumps or clumps of pie dough instead of the smaller pie dough crumbs or pieces. Both are fine. The yellow color just comes from your butter. If you use a lighter color butter than it won't be as noticeable.
Mireya says
I have made this recipe so many times, I love it!
Tori says
This recipe didn’t work for me at all. The curd never set right.
Jennifer says
I'm sorry to hear that it didn't, but appreciate the feedback.
Valerie says
I would like to just make the curd. I have puff pastry cups I want to fill with the lemon curd. Is there a way I can make curd in the stove? Thank you.
Jennifer says
This version is done in the oven, but if you check out my mini lemon meringue pies recipe, that lemon curd is made on the stove top. Hope this helps!
Kristin Dean says
I have made this recipes a dozen of times and it’s always a hit! Thank you so much for sharing this.
Emma says
can you bake and freeze for another time?
Jennifer says
Yes, you can bake then freeze for another time. Instructions for freezing lemon bars on can be found in the section above titled,"How to Freeze Your Lemon Bars." Happy baking!
Roxy says
Curious if these bars can be frozen?
Jennifer says
Yes, they can absolutely be kept frozen! Instructions on can be found in the blog post under the section "How to Freeze Your Lemon Bars."
David says
Wonderfully, easy and delicious!
Jennifer says
Thank you for the star rating and comment, David! So glad you enjoyed them!
Melissa Ann Shaw says
Do you think I could double recipe and bake in a sheet pan? I need to make 100!
Jennifer says
I never tested them doubling the recipe, but I don't see why you couldn't. I don't think that will give you 100 though.
