These creamy paleo lemon bars have a nut free, grain free honey-sweetened shortbread crust with a perfectly sweet-tart lemon custard layer to top! Dust with organic powdered sugar or dollop with coconut whipped cream for a deliciously dreamy dessert!
Welcome to your lemony weekend – I’m bringing you not one, but TWO brand new lemon-themed desserts!
I didn’t originally plan on sharing back-to-back lemon recipes, but after sneak-peaking tomorrow’s recipe on my Instagram stories, I received overwhelming requests from many of you wanting the lemon recipes NOW!
And, well, I’m here to please so here they are – beginning with these sweet-tart, perfectly creamy (and super simple!) lemon bars!
I’ve been making an effort to share nut-free baking recipes more often, since it’s a request I receive all the time.
These lemon bars are an easy paleo treat to make nut free since coconut flour actually makes a delicious shortbread crust that goes perfectly with the creamy lemon custard layer!
While making these bars, I wound up learning something sort of interesting: the filling (custard layer) needs to be poured onto the crust when it’s HOT out of the oven. Interesting, right?
For my first try, I allowed the crust to cool too long after pre-baking, and I was met with upside-down lemon bars when they were done baking.
That’s right – custard on the bottom and crust on top. Not ideal, although they tasted great!
Anyway, I was quick to blame the whole paleo/nut free recipe and wallow, until I decided to do some research. As it turns out, this is a somewhat common lemon bar issue that happens when the custard layer leaks into the crust while baking.
The salutation, is to pour the lemon layer over a fresh-out-the-oven-crust (hot) so the eggs immediately start cooking, creating a “seal” between the layers.
Luckily, my second batch came out a-okay in terms of flavor, texture, and appearance! Not to mention, with the timing issue fixed, these lemon bars are SO easy to make.
However, it’s not quite as easy to let them cool fully before digging in (but you MUST!) since they just look and smell so darn yummy!
Trust me though – they’re worth the wait, AND, to speed things up, you can chill in the fridge so they finish setting after they’re nearly at room temperature. For toppings, you can go with a dusting of organic powdered sugar, grated lemon zest, or a dollop of coconut whipped cream.
I hope you’re ready for tart-sweet heaven – let’s make these lemon bars!
Perfect Paleo Lemon Bars {Nut Free}
Paleo Lemon Bars {Nut Free}
These creamy paleo lemon bars have a nut free, grain free honey-sweetened shortbread crust with a perfectly sweet-tart lemon custard layer to top! Dust with organic powdered sugar or dollop with coconut whipped cream for a deliciously dreamy dessert!
Ingredients
Crust:
- 1/4 cup raw honey
- 1/3 cup ghee room temp*
- 1 egg room temp
- 1 tsp pure vanilla extract
- 2/3 cup coconut flour
- 1/4 cup tapioca flour
- 1/8 tsp sea salt
- grated Zest of 1 lemon
Filling:
- 1/2 cup fresh squeezed lemon juice about 4 lemons
- Grated zest of one lemon
- 1/3 cup + 1 Tbsp raw honey
- 3 large eggs PLUS 1 yolk
- 1 Tbsp tapioca flour
- 1/2 tsp coconut flour
Instructions
-
Preheat your oven to 350 degrees F. Line an 8 x 8” baking dish with parchment paper on the bottom and up the sides.
-
To make the crust, whisk together wet ingredients until smooth (or use an electric mixer, then stir dry ingredients in until well combined. Chill if necessary to form a dough (5-10 mins). Press crust into bottom of parchment paper evenly, then poke all over with a fork.
-
While crust bakes (see below), whisk together all filling ingredients in a large bowl until very smooth, set aside.
-
Bake crust 10-12 minutes or until lightly brown around the edges, then whisk filling mixture one last time and pour over HOT crust (important!) AND lower oven temp to 325 degrees F. Continue to bake another 15-18 minutes at 325, or until filling is just set in the center.
-
Allow the pan to cool on a wire rack completely, then refrigerate at least 2 hours before serving. Refrigerating overnight will work too.
-
To serve, cut cooled bars into 16 squares using a long sharp knife for neat edges.
-
Dust with organic powdered sugar, grated lemon zest or top with a dollop of coconut whipped cream and serve! Store leftovers covered in the refrigerator for up to 3 days.

I don’t see instructions for the filling. Can you add that? Thanks!
I was going to ask the same question. These look great!
Hi! I just added an extra step – you just whisk everything together until nice and smooth 🙂
Hi! I couldn’t find instructions for the crumb… Do you just mix by hand all ingredients at room temperature? Is it that simple? ☺
I can’t wait to try them! Thanks!
Oops! I’ll have to include that but yes you just mix together with a fork until crumbly 🙂
Oops ignore that, I was thinking of my crumb cake! Did you mean the crust for this?
Updated the recipe to include detailed instructions for making the crust, sorry about that!
I love lemon bars! These look so good!
Thank you!
These look amazing!
Thank you!
my mouth is watering. can’t wait to make these.
you should be able to use coconut oil or A Palm oil (sustainably sourced plz) coconut oil blend ‘shortening. Likely any fat you prefer should work.
Enjoy!!
These look amazing! I just tried making my first vanilla custard this morning and it turned out so well so now I’m on a custard kick! I’d love to try these.
That’s awesome! Hope you enjoy this one 🙂
I’ve been dying to see/get this recipe! Can you think of anything to replace the ghee?
Thank you!
Hi! Regular butter or coconut oil should work well 🙂
Awesome! I was looking/hoping for a non-animal product option, I’ll give the coconut oil a try. Can’t wait, lemon bars are my fav!
Does almond flour work instead of coconut and tapioca flour?
I was wondering the same thing! I have almond flour and coconut flour but not tapioca (so many flours)!
Nice article its very helpfull thanks for sharing
Made these yesterday, fantastic!! They were more tart than sweet, which is totally fine with me! I’ll have to add that powdered sugar after all! 🙂 🙂 🙂
I have never tasted something like this before! I was wondering if this would work in a ~18cmx12,5cm (about 7×5 inch) baking dish… I will buy a 8×8 inch one if this size is too small.
Would this smaller baking dish work with the brownies or lemon crumb cake and similar recipes?
Thank you!
I think so much it might be a little too thick!
Okay, thank you! I actually measured it work…it’s a 21×16 cm (~6,3×8,3 inch) baking dish, do you think I could use it?
Work=wrong*
These turned out very well – nice and tart with a touch of sweetness. A perfect spring treat! These bars will definitely be made again.
That’s great to hear, glad you enjoyed!
Michele,
Thank you so much for this recipe. I agree. These are pretty perfect. amazing! job well done! textures are all there, taste is 2 thumbs up, perfect balance of tartness and sweetness. I’m so pleased with how they came out. Dare I say… no need to ever make the shortbread version again!
Delicious!!!
These look delish! Are they Gluten Free?
Yup gluten, grain free.
I’m making these now for my kids bake sale and I am in charge of the nut free dessert. However, both the coconut flour and tapioca flour are made in a facility that uses nuts. The recipe is listed as nut free which is why I am making this. I don’t have kids with nut allergies so can I still serve these and call it nut free? I’m using Bob’s Red Mill flour but your link for the flour you used says the same thing??
Since that’s a cross contamination issue you might have to check with the kids’ school to see if it’s okay. Some are okay with ingredients not containing nuts but some that have known severe nut allergies might ban “made in a facility that also processes…” so, even though the recipe is nut free by ingredients, the possibility of cross contamination may be there depending on which brands are used.
Hi! Can arrowroot be used in place of tapioca in this recipe?
Thanks!
Think I can sub arrowroot for tapioca?
Yup that will work!
how about potato starch?
Hi!
These look AMAZING. I was thinking of sprinkling a little bit of organic coconut flakes to the top, but do you think this will mess up the custard when it bakes? I’m not sure how delicate the chemistry for these are. Can’t wait to try these!
I’m not sure about that one, I’d probably wait until it was nearly baked to sprinkle them on, or even broil a minute to toast at the very end
WOW! So excited to try these! Is it possible to include coconut milk/cream to add a more cheese-cake feel? They are for a hyper-allergenic bride who loves all things lemony & cheese-cakey type things. What would you suggest?
I have a key lime cheesecake tart that might be more of what you’re looking for. If you want lemon instead of lime you can most likely just sub it in – here’s the link –
I made these for my dad for father’s day and they were perfect. Thank you for this wonderful recipe.
These are amazing! They are so good, I made them twice. Will definitely make these a regular treat in our house!
Awesome, thrilled you loved them!
I made these for a family dinner and they were excellent! I love the strong lemon flavor and tartness that it gives with that hint of sweetness. I will make these again!
I love the idea of this and they look lovely! I tried making it myself but my lemon bars came out cracked although I followed the ingredients and directions 🙁 can you help me trouble shoot?
These exceeded my expectations! I was skeptical that the lemony top part (the part above the crust) would actually solidify and not soak through the crust — the lemon mixture is VERY liquid-like — so I doubled the tapioca and coconut flour amounts. It didn’t really help much because the lemony top part was STILL very liquidy when I poured in on the crust, but it eased my mind. The end result: absolutely delicious, although probably a little thicker (a tad more custard-like) than intended. Next time, I’ll make the recipe exactly as indicated. These really are delicious though — very tart. I didn’t put the powdered sugar on top because I didn’t think they needed it. They were just SO lemony and good! A definite thumbs-up. I’ll make these again!
Worst Lemon Bars EVER!!
I followed this recipe exactly (although I used butter instead of Ghee) And they look exactly like the picture. None of the flavors in the bars go well together at all, and they taste NOTHING like traditional lemon bars. The recipe plays out fine and bakes well, but once they are chilled and ready to eat the monsters of problems emerge. Starting with the lemon filling, the honey does nothing as a sweetener what-so-ever. It only adds the odd flavor of raw honey to the bars. The egg flavor is one of the most present flavors in the whole recipe and it does not go well with the lemon nor with the honey. It is a gag inducing flavor as one does not expect it to be present in a lemon bar recipe. The lemon flavor is not particularly strong, but it is quite tart. The texture of the filling is not creamy as described, it is very gelatinous. Not like the custard texture in traditional lemon bars. Moving on to the atrocity that is the crust, the flavors of the coconut flour also don’t pair well with the egg-y filling. The crust has a prominent coconut flavor, and it doesn’t taste anything like the shortbread that the recipe claims it should. Therefore, the crust doesn’t hide or add to any of the honey flavor, nor the egg flavor, as I would have liked it to. The texture of the crust is very soggy, almost like eating moist, gluten-free bread. The recipe is missing the light, crispy shortbread texture of the crust in traditional lemon bars. Note that the bars also smell horrible, of egg and almost a cornmeal with lemon undertones. It is not appetizing at all.
Overall, I am very much disappointed by this recipe, to the point I wish I never birthed such an abomination in my precious glass 8×8 pan. If there was a neutral sweetener used, and one that could cover up the strong egg flavor, I might cut the bars some slack. Yet no; there is nothing to hide anything, and the egg flavor is disgustingly present. The poorly paired flavors are competing to see which one is more overpowering- Egg, honey, or coconut. None go well with the tart lemon used in the bars.
I will say that there is the slight possibility that I used a bad egg, however, I just opened a freshly bought carton of natural eggs and I find this possibility very unlikely. I hope that you can possibly fix these issues in a further version of these bars. Have a nice day.
I am unhappy campers dad. We must have had an ingredient that was bad. If others had the same result we did, there would be no good feedback here. We could stand to be a little more positive with our constructive criticism. For example: Our bars did not turn out well. We followed the recipe but used butter instead of Ghee. the lemon flavored top was not bad but the cake part on the bottom tasted quite bad. Does anyone have an Idea of what went wrong? Has anyone else had the same problem? We are excited to try again. Thanks!
Will Crow, please do not tell me how to write a criticism. These cars deserve every word I said about them. I understand how you may feel, and I do not like starting drama in the comments of a recipe page, but I do not believe that reply was necessary. Thanks and have a nice day.
I agree with you will crow, the negative comments left by unhappy camper could have been kinder or at least could have offered some suggestions on what would have worked better for this recipe if it was found lacking. I feel words like “atrocity”, “disgustingly”, and this comment: “I wish I never birthed such an abomination in my precious glass 8×8 pan” are just plain mean spirited and uncalled for! I think this recipe was delicious and I will pass it on to my other Paleo friends. It’s sad that someone who didn’t like it was so nasty in saying why they didn’t. This blogger Michele takes her time and effort to bring us recipes and if not for nothing else kindness should be shown for this reason alone!
I made your lemon squares with almond flour from your cookbook and they were fantastic. Family raved about them.
Hi! Did you substitute all of the flour for almond flour? I’m almost out of coconut flour and completely out of tapioca and my husband has been craving lemon bars for 2 weeks now so thought I’d ask. Thank you!
I suggest you find another Paleo blog that you will like better instead of trashing a recipe that 95% of us found delicious. If you don’t like the recipe, move on instead of being so mean and nasty!
These were delicious! I think I will try the coconut whipped cream to sweeten it up a bit. Do any other your other desserts use this crust? If not they should!
Excited to try this! Is this freezer friendly?
Hi there, what consistency and thickness should the crust be? Thanks! Love your recipes!
Sadly, I just pulled these out of the oven and the filling has soaked into the crust. I poured the filling immediately over the hot crust after baking as instructed. Confused!
Great easy recipe!
I am a professional chef with a Private Events company in LA. Had a dinner party the other night for some regular clients. They eat healthy and really do no refined sugars. Long story short, they were a hit! To be honest, I did not think they would really turn out as well as they did! Again, great recipe and very straight forward!
Thank you!!
I made this recipe and the lemon filling soaked underneath the crust. Has this ever happened to you? It’s so odd… I flipped it over after refrigerating. They still taste amazing, but it was strange!
The crust was quite disappointing. Lemon filling good, but scant.
Has anyone tried using maple syrup instead of honey?
Hi. How in the world does an 8*8 baking dish yield 16 bars? They must be bite size! I feel like that small a dish would only make 4-6 decent size bars.
I made these in a 8×8 pan and cut 4 rows and then turned the pan and cut 4 more rows….4 x 4 = 16 and these were not small servings, I would say at least 3 or 4 nice size bites.
Can I sub coconut oil ghee in the crust? Can’t wait to make these!!!!
Que receita doida,mal explicada,umas palavras que não entendo,varinha mágica,sal do mar, 1temp de sala de ovo,que isso,não sei?
Hi Michele! I have to tell you…I made these lemon squares for dessert this weekend (my Mom LOVES lemon) and oh em gee!! These are the real deal!! I loved how you even made them the same way as “traditional” lemon squares, pouring the lemon over the hot crust. The flavor was spot on tart lemon with just a hint of sweetness! My problem is I want to eat all of the leftovers!!! I really love all your recipes, thanks for all you do!!
I’m so happy to hear you enjoyed them!
These lemon bars are to die for, they don’t even taste Paleo. I followed the directions exactly and. They came out great.
These were not our favorite. We made your lemon crumb cake, your lemon curd and these lemon bars. Filling is ok. Crust is not my favorite. I think maybe if they were made w almond flour and maple syrup they’d be better. This is the first recipe I’ve made of yours that I didn’t love.
yumm, thank you! non paleo friends & family loved it & thought it was store bought.
OUTSTANDING!! I am a great cook but my baking skills can use some help BUT these came out PERFECTLY!! My hubby is a lemon square snob and he gave this 5 stars!! Thanks so much for such a great and easy recipe, Paleo Running Momma! 🙂 <3
I made these lemon bars yesterday. I have never made lemon bars before as I am not much of a baker. I followed the recipe exactly and the process was very easy for me, they looked beautiful right out of the oven and the taste was amazing. We absolutely love them! The custard is creamy and tart and the crust is not too thick, the ratio of custard to crust is perfect. I will definitely be making these again.
Once again another amazing recipe from you. I did use coconut sugar instead of honey for the crust and turned out amazing. Looking forward to trying more of your delicious recipes. 🙂
I make these all the time and they’re AMAZING!!!
Do we have to use the coconut flour or can it be something else
These lemon bars are literally my favorite everrrr!!! I’ve made them for every business party and family holiday/birthday party n everyone loves them! They all ask for the link to this recipe. I’m unsure why some people find them unappealing. I think they are perfection! The perfect blend of sweet and tart and the consistency is awesome! Thanks so much for this recipe!!!
Not low carb, the way paleo should be, though.
I followed the recipe exactly and these were a gross soggy mess. Yuck!
Do you know if I can use a chia egg instead of normal eggs in crust?
You might be able to use a flax egg. I don’t think the crust is wet enough to support a chia egg.
I brought these to a birthday party for a lemon loving coworker who is paleo and they were an absolute hit. I didn’t have enough coconut flour in the house so split the quantity for the crust 50/50 with superfine almond flour. Also swapped the honey for granulated monkfruit sweetener with perfect results. They were deliciously tart and I enhanced the sweetness with a dusting of powdered confectioner’s sugar on top. Would definitely make again.
Can almond flour be used instead of coconut flour in the crust?
Can we use almond flour instead of coconut flour for the crust? Thanks!
These were great and my family loved them! The recipe is so easy and I love not having to cook the lemon filling on the stove. Making a second batch!
LOVE this recipe! The texture is AMAZING and it’s perfect for using up my lemons.
Perfect sweet/tart ratio, loved these so much! Personally I’d like the crust to be a little bit thinner but the taste is delicious. Very easy recipe to follow. Do these freeze well? Thank you!
These turned out SO GREAT! I ended up making them into key lime bars for my brothers birthday, and he loved them. 🙂
These were perfect. I did not put any sugar on top:)
The title doesn’t lie! These bars are the perfect balance of sweet and tart and I think the custard topping has a perfect texture. There was a slight flavor of coconut from the coconut flour that I would have preferred to not be there, but other than that the bars tasted just like traditional lemon bars!
These are incredible! A crowd pleaser every time.
can u subsitute lime for the lemons?
These turned out so good and most allergy free… These were gorgeous! My children and husband tried and love these… They didn’t suspect that were Paleo ?…
Thank you so much for sharing this recepy it made my day (paleo + nut allergy)
I really want to try this recipe and I have all the ingredients EXCEPT tapioca flour. Can I substitute that with something else?
Thanks.
Help!! I just made these lemon bars…I did everything by the book and the crust looked great so I poured the filling mixture into the hot crust and no matter how long I kept baking them, the filling never set up! I pulled it out to cool and still runny. So now it’s in the fridge. I can’t figure out what went wrong. I did sneak a taste and it’s absolutely delicious…but soupy!
Could you leave out the tapioca flour? What is the purpose of it?
Awful! The lemon bars smelled and tasted like egg. Not sweet enough. I used an immersion blender to blend, followed the recipe and was so disappointed. Needless to say I use only organic ingredients and this was a waste of a lot of money, from the organic lemons to the organic pasture raised eggs. This recipe was awful.
Made it exactly according to recipe. Excellent. Thank You!
Amazing! I had to cook the crust another 3-5 minutes and same with the filling but it turned out spectacular! One of my new favorites and is being added to the rotation. Not overly sweet and have a really nice texture. Reminds me of the ones I used to have before I was paleo, so that’s a huge compliment!
Can I use monk fruit instead of honey?
do you think maple syrup could replace the honey or would that make the taste a little weird?
Yum!! I just made this! It’s so yummy! I was really craving something lemony and this definitely hit the spot! And usually I have to use coconut sugar so its costs an arm and a leg, but this used honey! Will definitely make again
These turned out perfectly! Thanks so much for a winning paleo recipe that was easy to make!
The lemon filling was yummy, but the crust tasted like a corn tortilla. I’m not sure if this unpleasant taste was from the coconut flour or tapioca, but I’ll definitely try some new variations of this recipe to try to get the taste right. Unfortunately, the flavors in this bar don’t quite compliment each other. I’ll definitely be trying this again with my own crust recipe. Thanks for putting the time into creating this recipe! While not my favorite, it did show me that making a paleo lemon bar that my husband and I can enjoy might just be possible! The filling was really delicious!
