An easy recipe for Gluten-Free Lemon Bars. These tangy lemon squares are made with a buttery shortbread crust and a fresh lemon curd filling. This gluten-free dessert also has a dairy-free option.
Gluten-Free Lemon Bars
One of my favorite Springtime desserts to make is gluten-free lemon bars. The flavor of lemon just screams “Spring” to me. I really enjoy desserts that are lemon-flavored, like my Gluten-Free Lemon Cake.
I especially love how easy lemon bars (also known as lemon squares) are to make! I used to make these lemon bars when I was a kid using my Mom’s Betty Crocker cookbook.
The good news is that lemon bars are super easy to make gluten-free. Making the shortbread crust gluten-free was easy to adapt from the traditional lemon bar recipe.
You can see just how easy it is to make gluten-free lemon bars in the recipe video.
How To Make Gluten-Free Lemon Bars
Shortbread Crust
- Preheat the oven to 325°F. Line the bottom and sides of a 9 × 13 glass baking pan with parchment paper. Make sure the parchment paper hangs over the side of the pan to help make lifting the bars out of the pan easier.
- In a large bowl, mix the melted butter, sugar, pure vanilla extract, and salt. Add the gluten-free flour and stir to completely combine and the dough forms. The dough will be thick. (photo 1)
- Firmly press the dough into the lined pan evenly, making sure the layer of crust is even (photo 2)
- Bake for 20-22 minutes or until the edges are very lightly browned. Remove from the oven and set aside. (photo 3)
Lemon Filling
In a large bowl, whisk together the eggs. Add the sugar and whisk until combined. Add the lemon juice and pure vanilla extract and whisk until combined. Add the gluten-free flour and whisk until completely combined. (photo 4)
Pour the lemon filling over the warm crust. (photo 5)
Bake the bars for 26 minutes or until the center is just about set and no longer jiggles. (photo 6)
Remove bars from the oven and cool completely at room temperature for 1 hour.
Cover the bars with plastic wrap and place them in the refrigerator for 2 hours until fully chilled.
Once the bars are chilled, lift the parchment paper out of the pan using the overhang on the sides of the pan.
Dust the top of the bars with powdered sugar and cut into squares before serving.
For smoother squares, wipe the knife clean between each row that you cut.
Cover and store the leftover lemon bars in the refrigerator.
Do I Have To Use Fresh Squeezed Lemon Juice?
No, you can easily use bottled lemon juice. That is what I use. I like to use shortcuts in the kitchen when I can.
Squeezing your own lemon juice is not necessary. If you decide to squeeze your own lemon juice, you will need about 4 large lemons to make one cup of lemon juice.
Can I Freeze The Lemon Bars?
Freezing lemon bars are super easy! Cut the cooled bars (without the powdered sugar topping) into squares, then place them on a baking sheet. Flash freeze for 1 hour. Wrap each bar in aluminum foil or plastic wrap and place them into a large freezer bag.
The lemon bars can be frozen up to 3 months. Thaw the lemon bars in the refrigerator overnight. Dust with powdered sugar before serving.
Why are there air bubbles on top of the baked lemon bars?
If you have air bubbles on top of your baked lemon bars, that is completely normal. This happens when the air from the eggs rises to the surface.
Sometimes this happens and sometimes it does not. Either way, the gluten-free lemon bars taste the same and the powdered sugar covers it up!
Gluten-Free Flour
These gluten-free lemon bars were made with an all-purpose rice flour cup for cup blend. A cup for cup all-purpose gluten-free flour blend is one that already has the starches and xanthan gum included in the mix.
Most gluten-free all-purpose flour blends on the market now have the starches and the xanthan gum already mixed in them. Xanthan gum is important because it helps to replace the elasticity and texture of gluten.
If your gluten-free flour does not have xanthan gum in it, you should add 1/4 teaspoon of xanthan gum per 1 cup of flour.
My favorite brand of gluten-free flour is Pillsbury gluten-free flour.Not all gluten-free flours are created equal. You may experience different baking results depending on the gluten-free flour blend you choose.
This recipe will not work with almond or coconut flour.
Tips For Measuring Gluten-Free Flour
I have found that the best way to measure gluten-free flour is to use the “spoon & level” method. Use a spoon to scoop the flour out of the bag into a dry measuring cup (not a Pyrex measuring cup used for liquid). After spooning the flour into a measuring cup, use the back of a knife to level the flour off the measuring cup.
Please do not use a measuring cup to scoop the flour directly out of the bag. If you do, you may get more flour than the recipe calls for because the flour often gets compacted in the bags.
Dairy-Free Baking
I have also included a dairy-free option for this gluten-free lemon bars recipe. My husband, my youngest sons, and I are also dairy-free, so I always try and have a dairy-free option for my recipes.
For the dairy-free option, I used Smart Balance butter. So, now you too can enjoy gluten-free and dairy-free lemon bars.
Some of my favorite dairy-free alternatives that I like to bake with are unsweetened almond, cashew or coconut milk (beverage in the cartons). I also like baking with coconut oil and Smart Balance butter.
