Healthy lemon bars that are gluten free and paleo make for the most perfect easy summer dessert. Made with an almond flour and coconut flour crust, and a simple filling sweetened with only maple syrup. Your whole family will love this healthy dessert recipe.

Have you ever made lemon bars before? How about healthy lemon bars? No? Well we are about to change that and I’m pretty certain that it won’t be the last time that you do because it is easy and incredibly delicious.

Traditional lemon bars, while super tasty and one of my favorite childhood desserts, are packed with less than healthy ingredients, so in a typical Erin Lives Whole effort to take a traditional baked good and turn it into a healthier dessert.

And so that’s exactly what I did! I created a healthy lemon bar recipe made totally gluten free with ingredients like coconut flour and almond flour. Instead of refined white sugar we replaced it with natural maple syrup, but I swear that healthy eaters and non healthy eaters a like will love this recipe!

I love having lemon desserts on hand because they always taste so fresh. You have to also try my Healthy Lemon Cookies, and as a bonus they are gluten-free.

Ingredients in healthy lemon bars

There are only a few simple ingredients in this recipe for healthy lemon bars. You may already have all of the ingredients on hand. Now you’re well on your way to making some of the best creamy, yet firm enough to hold together lemon bars.

Lemon bar crust

  • almond flour
  • coconut flour
  • coconut oil
  • maple syrup
  • vanilla
  • salt

Lemon bar filling

  • eggs
  • lemon juice (freshly squeezed!)
  • maple syrup
  • lemon zest
  • coconut flour

How to make lemon bars

You’ll want to start by making the crust! We use a blend of almond flour and coconut flour for the crust, as I’ve found that yields the sturdiest result while still being moist enough. All almond flour and it is too soft. All coconut flour and it is too dry. So we meet in the middle and found a perfect crust!

Mix together your flours, coconut oil, maple syrup, vanilla, and salt. This will create a dough that you should be able to press into a greased or parchment lined 8×8 pan. Then throw that baby in the oven and bake!

While the crust is baking, prepare your filling so that you will be ready to pour it on top of your hot crust right when it comes out of the oven!

Squeeze your lemons to get fresh lemon juice, then whisk that together with eggs, maple syrup, and lemon zest. Sift in your coconut flour for extra fine texture and then whisk until there are no clumps!

Right when your crust is done baking, lower the oven temp down and pour your filling on top. Let it bake until set in the middle (a little jiggle is ok!) then cool at room temperature. Once cool, refrigerate for at least 4 hours.

Cut and serve! I like to sprinkle powdered sugar on top as well. So good!

What’s the best way to store lemon bars?

Store the lemon bars in the refrigerator. They are best eaten within 48 hours, as the crust will begin to get a little bit soft. So these are one of those desserts that best made the night before and served the next day!

We also freeze any leftovers and then defrost in the fridge to eat for the next day.

    Can I use gluten free flour instead of coconut?

      Hi Kandy, yes of course. Just check the ratio since some flours aren’t 1:1. Let me know what flour you use and how the bars come out!

    These lemon bars are a staple in our household! They are very easy to make and turn out perfect each time. The most difficult part is waiting for them to cool and set completely!

    This recipe is AMAZING! My favorite!!! All my family enjoyed the lemon bars! The only problem I have is that my lemon bars have tiny white dots. I made them twice. The second time I tried with sifted coconut flour but the same result. Any suggestion so they dont come out with white dots? Thank youuu for this amazing recipe! 🤤

      Hi Ana, thank you so much for the kind words! I’m so glad your family enjoyed them!! To get rid of the white dots, be sure to whisk it extra well! White dots means you haven’t broken up the egg whites completely. Let me know how it comes out next time. As they say the third time is the charm!

    What can I sub for coconut flour in the filling? I have almond flour, whole wheat flour and whole wheat pastry flour.

      Posted on 8/2 at 7:32 pm

      Hi Melissa, feel free to use whichever flour you’d prefer. Be sure to look up the specific measurements for whatever one you choose, as most flours will not substitute at a 1:1 ratio for the coconut flour but any of the above should work as long as the ratio is correct. Let me know how it goes! 🙂

    These lemon bars were SO GOOD! First time making lemon bars and they were a hit! I didn’t have coconut flour so replaced the measurements of that in the recipe with whole wheat flour and it worked great! The crust may have been slightly more moist than if I had used the coconut flour but we didn’t mind the texture at all. Thanks so much for an easy to follow and delicious recipe- the perfect summertime dessert 🙂

      Hi Hannah, thank you so much for the kind words and so happy you made it your own. If you use whole wheat flour next time, I’d recommend using about 1 cup of the wheat flour. Coconut flour behaves differently, and it is generally recommended that 1/4 – 1/3 cup of coconut flour can be substituted for 1 cup of wheat flour. Hope this helps and let me know if you try them again! 🙂

    SO AMAZING. All around – the texture, the flavor – all of it! Made it with sugar free maple syrup & followed the recipe exactly. Didn’t taste healthy at all it was SO GOOD!
    Only issue I had was not having an 8×8 pan.. Normally try and shrink my pan size with aluminum foil, but the filling was completely liquid so it seeped underneath. Made it work though by tilting the pan… lol still turned out great, and worth buying a pan for!!!

    This is SO good. The crust is flaky and just the right amount of sweetness. The filling is the perfect texture, lemony, and sweet. Just made tonight as an early summer dessert and will def make again!

    The flavor on these was amazing…just the right amount of tart and sweet. The crust was soft and the filling didn’t quite set…next time I’ll extend the baking time for both steps. Thanks for the great recipe!

      Same with me! I’m at 8000 ft elevation so maybe that’s why but next time I’d extend by like 3 minutes for each layer.

    The only lemon bar I’ve had was from Whole Foods. Full gluten, full fat, full sugar -amazing. I’ve been wanting lemon bars again but wanted to go a healthier route. These lemon bars turned out great! I really love them and don’t feel guilty while eating them. I even made some changes to the recipe based on what I had. I used half honey half maple syrup. The recipe was very forgiving as I did a couple things “wrong” and thought I was doomed. But they turned out great and will be even better the next time I make them. Thanks Erin for this recipe!
