Lemon Squares are easier than you might think. Baking is still a bit intimidating for me, as I’ve talked about before. When I started this blog, I couldn’t cook ANYTHING, and I for sure couldn’t bake anything. Cooking seems to be so much easier to me.
Throw this in, leave this out…most recipes are easy to customize and hard to ruin. Baking is more precise. It seems like more of a skill. Along the blog’s journey, I’ve had some baking successes that I’m so proud of! These Gluten Free Lemon Bars are a favorite.
Before I attempted this easy lemon bars recipe, my mom helped me make her famous Oatmeal Chocolate Chip Crinkles, I made an amazing Raspberry Moscow Mule Bundt Cake, and I tackled and perfected Mini Nutella Cheesecakes (nevermind that those are no bake. shhh!).
Today’s recipe, GLUTEN FREE LEMON BARS, has quickly become one of my favorite gluten free dessert recipes on the site. They are SO creamy, dreamy, and EASY! You’ll crave them year-round, but they’re especially perfect for Spring and Summer. Lemon Squares just can’t be beat in my opinion.

How do you make Gluten Free Lemon Bars?
Part of what makes these Gluten Free Lemon Bars oh so easy and perfect is Bob’s Red Mill Gluten Free 1 to 1 Baking Flour. You heard that right, ONE TO ONE. No more adding in special ingredients to make gluten free flours work with your favorite recipes.

Thank you Bob’s Red Mill! Pat thanks you too, he’s the inspiration behind these lemon squares. He asked me to work on some gluten free goodies and this was my first attempt. Now that I know how easy they are, they won’t be my last.

How to Make Lemon Bars (Step by Step Recipe)
-
Heat Oven to 350°F. Spray a 9×9 baking dish with nonstick spray and set aside. (I also like to line with foil and then spray…makes pulling them out of the pan much easier)
FOR THE CRUST
-
In a medium bowl, combine flour and sugar. Use a fork or knives to stir in the butter until a crumbly mixture results. Add water a bit at a time. Take mixture and press evenly into the bottom of the pan.
-
Bake for approximately 25 minutes until slightly golden and set.
FOR THE FILLING
-
In a mixing bowl, stir together all of the filling ingredients until smooth.
-
Pour mixture over the still-hot crust.
-
Bake 22-26 minutes or until set in the middle. Let cool on the counter for a minimum of two hours. Cut into squares and sprinkle with powdered sugar. If not immediately serving, store in the fridge.

Tips for Making Lemon Squares
I sampled a few variations before settling on this Lemon Bar Recipe. I’m SO happy with the result. These gluten free Lemon Bars are the right amount of creamy, tart, and crust altogether.
- If you want to make this dessert with regular flour (instead of gluten free) that’s no problem at all! Just use all-purpose flour in place of the gluten free flours. Also, I hope you’ll check out all of our Gluten Free Recipes!
- Powdered sugar is gluten free as long as it uses cornstarch or tapioca starch as its base. so just be sure to double-check the ingredient list.

FAQ for making Lemon Squares
Do you put Lemon Bars in the fridge?
I recommend keeping them cool. You can keep them in the fridge or on the counter in an airtight container for 2-3 days, but the refrigeration will only enhance the flavor of the bars and keep them extra creamy.
How much is the juice of one lemon?
On average, each lemon has 2 tablespoons of lemon juice and 1 tablespoon of lemon zest. Great info to know!
How long can you keep lemon squares?
I recommend no more than 2-3 days in an airtight container.
How long is a lemon good for?
A lemon can stay good and fresh for up to 1 week at room temperature and 2-3 weeks in the fridge. Cut lemons can stay good for 2-3 days in the fridge.

Interested in making this ahead of time. Can it be frozen?
Yes! Cut into individual squares, then freeze on a lined baking sheet until solid, about 1-2 hours. Transfer to an airtight container to store for up to 3 months!
Made these for an event and everyone went CRAZY for them! They didn’t even know they were GF either 😉
I was wondering if you think I could use an egg replacement (just egg) in the recipe? My son is allergic to eggs, but I’d love to be able to make these for him!
I’m so glad they were a hit! I’ve not tried with an egg replacer, but let me know how it goes!
I tried this as I wanted to bake something for a friend who avoids gluten. I’ve made many a lemon bar and these just did not do it for me. The crust didn’t taste nice and buttery the way the crust usually would and the topping came out tasting floury even though I followed the recipe to a T. Disappointed given the other great reviews and wouldn’t repeat.
I’m sorry this recipe didn’t work out as expected, Lorraine! How did you measure the flour? I recommend using a scale for the most accurate results, or using the spoon-and-level method to avoid packing the flour in the measuring cup!
Does anyone know if you can use Bob’s Redmill gluten-free flour to make this rather than the 1:1 flour? The grocery store didn’t have 1:1 and I’m hoping to make this for NYE tomorrow. Thanks!
I have not tested this recipe with regular gluten-free flour. I always recommend 1:1 flour for the best results!
I made these and they were fantastic. I like to measure with a scale for baking and I’m questioning the grams for the lemon zest. Is it meant to read 1-2 grams not 12? At least that’s now I see it .
Thanks,
Mary
1 tablespoon of lemon zest weighs 6 grams, so 2 tablespoons weigh 12 grams! A teaspoon would be 1-2 grams.
Hi Becky, This lemon bar recipe deserves more than 5 stars in my book. I made the recipe as written, but technique wise~~here are 2 tips that may help some readers:
1. I made the base crust in food processor. I just roughly cut up a stick of frozen butter and tossed it in food processor bowl with other crust ingredients. I used a little more than 2 tablespoons of water for the crust to roughly come together.
2. When patting the crust base into the pan, I dampened my fingers with a little water and this really helped to keep the dough off my fingers and to get it down smooth into the pan
Those are some great tips, Judy!
We made these lemon bars for a family gathering. One person has celiac disease so the entire day was all gluten-free. These bars are AMAZING and very easy to make. They were gobbled up quickly and we’ve gotten many requests for the recipe! (I’ve shared your link). Thank you for sharing!!!
Thanks for sharing with others!
Looking for a quick gluten free Lemon Bars and I found this website. Just want to leave a note that the bars where delicious and I even used an alternative sugar for baking. Came out perfect from the oven, chilled for 2 hours. Took it out from refrigerator dust it with sugar on top and my husband and I loved it.
Thanks for sharing!!
