I am feeling a little guilty making sweet treats this week. Mr. Fearless Dining is out of town, and I have nobody to share these with…except the kids :-). He really hates missing out on dessert, so I will have to hide a few so he can try them when he gets back in town. 

These are by far one of my kids’ favorite desserts! If you love citrus in your desserts, check out these amazing Gluten Free Lemon Dessert recipes too!

Why I love these gluten free lime bars:

  • They are a great excuse to use limes in a dessert!
  • The blend of sour lime and sweet flavors tastes so good together.
  • Not only are these gluten free lime bars delicious, but they are so easy to make!
  • You can freeze these bars easily to have them when needed!

Ingredient Notes:

  • Gluten Free Flour Blend – I tested this recipe with Bob’s Red Mill 1:1 Blend. Other blends should work, but make sure they have a binder like xanthan or guar gum.
  • Almond Flour – I used almond flour to add protein to this recipe. See the Substitutions section below to see how to make this recipe nut-free.
  • Sugar
  • Shredded Coconut – Use unsweetened coconut.
  • Baking Powder – I recommend aluminum-free.
  • Limes – You can also use key limes to make these Gluten Free Key Lime Bars.
  • Eggs – Size large.
  • Butter – Use unsalted butter. See the substitutions section for dairy-free instructions.
  • Condensed Milk – Use coconut condensed milk if you are dairy-free.

Tips For Sucess:

  • Make these bars in an 8×8 pan or a tart pan if you want to get fancy!
  • Use fresh regular or key limes. Bottled lime juice will work in a pinch, but fresh lime juice yields better flavor.
  • Use a good gluten free baking spray so these bars don’t stick to the pan.


  • If you can not eat coconut or nuts, use the crust recipe from these Gluten Free Cranberry Bars. This easy gluten-free crust recipe will make these gluten free lime bars nut-free and/or coconut-free.
  • To make this recipe dairy-free, use plant-based butter and coconut condensed milk.
  • If you can’t find limes in your local grocery store, it is okay to use lemons. One of my readers used oranges in this recipe to make orange bars!

Recipe Step-By-Step Directions:

A mixing bowl full of gluten free crust dough.

Step 1: Add the gluten free flour, almond flour, shredded coconut, and brown sugar to a large mixing bowl. Whisk to blend.

The crust pressed into an 8x8 pan.

Step 2: Pour the crust mixture into a greased 8×8 baking pan. Spread the mixture all around the bottom, the use your hand to press it flat in the pan. Come up a little along the sides with the crust.

Step 3: In a medium-sized mixing bowl, whisk the eggs, zest, lime juice, condensed milk, and sugar.

Step 4: Pour the lime mixture over the crust.

Step 5: Bake the bars at 350º F for 30 minutes until the top is firm. Remove from the oven and allow the bars to cool on a cooling rack for 30 minutes.

Step 6: Loosely cover the pan with plastic wrap. Put into the refrigerator for one hour to chill.

🔑 Sandi says: I like to let the bars get to room temperature first so the bars don’t “split” when cooled too quickly.

Store these bars in an airtight container in the refrigerator. They will keep fresh for up to 4 days.

You can also freeze them in a zipper bag. To do this, you will want to flash-freeze the bars before putting them into the bag. Lay the bars out on a baking sheet and freeze the bars for 1 1/2 hours. This will slightly freeze them so that they don’t stick together.

Recipe FAQ:

How do you know when the lime bars are finished baking?

If you bake the lime bars for 30 minutes, they should be baked. The toothpick test doesn’t work well on this recipe because the lime mixture doesn’t get firm the way a cake does.

What is a lime bar crust made out of?

The crust is made from flour, almond flour, and shredded coconut. It is almost like a shortbread crust.

Do lime bars have to be refrigerated?

I highly recommend storing these lime bars in the refrigerator. They are moist and can spoil quickly if left out.

  1. You can make this recipe dairy-free by using vegan butter or coconut oil instead of butter and coconut condensed milk.
  2. You can substitute lemon if you do not have limes. Fresh juice is better than bottled.
  3. Use almond flour and not almond meal.
  4. To make these nut-free and/or coconut-free, use the crust recipe from my Gluten Free Cranberry Bars recipe.
  5. Store in an airtight container for up to 4 days in the refrigerator.
  6. Freeze by flash-freezing the bars, then placing them into a freezer bag.


Please know that every gluten free flour blend has a different starch to grain ratio. If you use a blend I didn’t test, you may need to adjust your moisture levels in your baked goods.

    1. My attempt was a disaster-it basically bubbled up and over the top of the dish and created alot of smoke and yuck. Any clue why?

      1. Hi Kristen, I haven’t heard of this happening, so let’s break it down. What gluten free flour blend did you use, did you substitute any ingredients, and what size pan did you use? What position was the rack in the oven? I typically try to bake with the rack in the middle of the oven.

  1. 5 stars
    I lined a 9 by 9 inch square metal pan with foil, since my 8 by 8 inch glass pan is not perfectly flat on the bottom. Used plenty of PAM. Also, did not have unsweetened coconut, so I used shredded Baker’s brand sweetened and dropped out 1 tablespoon of the brown sugar from the crust. Added 1 T. of gluten free flour to the lime batter for a bit more body in the filling. Very good recipe with a macaron type bottom crust. Cut after chilling for best presentation.

  2. Could I substitute coconut yogurt for condensed milk? If YOU have any other suggestions ,I’d GREAT~LY APPRECIATE it 😀 I look forward to hearing from YOU <3 HUGS!!!!!

    1. Hi there. I have to be honest, I really don’t know. I say experiment and come back and let us know how it turned out.

  3. A big bag of lemons would be great! 🙂
    How do you like the Bob’s Red Mill Gluten Free Flour Blend?

    1. Bob’s 1 to 1 gluten free blend is my very favorite to date. My second favorite is Authentic Foods Multi Blend, but it is a lot more expensive.

  4. I wish I lived near you…I’d happily take some lemons off your hands! But, I love limes too…I cook with them both all the time! Your snack bars look awesome!

  5. I would be sad to miss out on these too! I am all about citrus lately, and these look amazing!
