How do you make gluten free lemon bars?

There are three basic steps to making these easy lemon bars:

  1. Assemble the crust. It’s super easy and all mixed up in on bowl. Pat it into the pan and bake it.
  2. Next make the lemon curd. All the ingredients are mixed in a pot, heated until thick and then strained out. You’ll whisk in butter to make it smooth and creamy.
  3. Next you pour the lemon curd into the baked crust and back in the oven it goes for a bit longer!

Lastly, you let the whole thing cool before slicing and serving. Optionally you can dust with powdered sugar to make it just a bit more pretty! But that’s not essential as these are already sweet enough.

  • Cook Time: 40 minutes
  • Total Time: 50 minutes
  • Yield: 9-12 1x
  • Category: Dessert
  • Cuisine: Gluten-free, refined sugar free



  • 2 cups (192g) almond flour
  • 2 tablespoon (16g) tapioca flour
  • 4 tablespoons grass-fed butter OR coconut oil, melted
  • 1/4 cup pure maple syrup or raw honey
  • 1 teaspoon vanilla
  • 1/4 teaspoon sea salt

Lemon Curd:

  • 3 large eggs
  • 4 large egg yolks
  • 1/2 cup beet sugar OR maple sugar
  • Zest from 4 lemons
  • 3/4 cup fresh-squeezed lemon juice (from about 6 lemons)
  • 1/4 teaspoon sea salt
  • 8 tablespoons (1 stick) unsalted butter, softened and cut into cubes
  • Powdered sugar, for dusting


  1. Pre-heat the oven to 350 degrees °F and line an 8×8 baking pan with parchment paper and set aside.
  2. Make the crust: Add all ingredients to a large mixing bowl and mix well. Press evenly into the baking pan. Bake for 25-30 minutes, or until crust is lightly brown.
  3. Meanwhile, make lemon curd: Place whole eggs and yolks, sugar, lemon zest and juice and sea salt in a medium pot.
  4. Over low heat, whisk the lemon curd until it becomes thick enough to coat the back of a spoon and take off heat. This process should take around 8-10 minutes.
  5. Using a fine mesh strainer, strain the lemon curd into a medium mixing bowl. Add in the butter and stir well until melted.
  6. Pour lemon curd over the crust. Bake for an additional 10-15 minutes. Set aside, let cool completely, cover, and store in the refrigerator for at least 3 hours to set.
  7. Top with powdered sugar, slice, and serve!

  1. This recipe looks amazing and can’t wait to try it! Perfect for summer! Have you tried using ghee in the curd instead of butter? Wondering how it would turn out, for a dairy-free approach.

  2. A blitzed coconut sugar be ok? when it needs to disolve like this i usually blitz in thermo until i have an icing sugar consistancy. Would this work???? Thanks. they look yummo!

  3. I love lemon bars
    Any suggestions for substituting the butter or oil. Can applesauce take the place?

  4. Yes! Yes! Yes! Springtime means lemon bars, can’t wait to make these AGAIN so so good!! **don’t try and sub coconut sugar if you’re going for looks- makes the bars look like pumpkin pie, oops! Still taste great though!!

  5. What size lemons do you use for zesting? I by the ones at Costco and it was a lot of zest… turned out a bit bitter. Any idea on how many tablespoons of zest? !st time I made these I just wanted to eat the whole pan though.

  6. I just made these with coconut sugar! I freaked out thinking they would come out brown but they didn’t! Just a darker yellow. Can’t wait for them to cool and sprinkle with powdered sugar. I also used Schar’s honey grahams for the crust as I didn’t have enough almond flour.

    1. We haven’t tested any alternative sugar-free substitutes with these, unfortunately, so we can’t advise.
