Gluten Free Lemon Squares

Today I’ve partnered with Bob’s Red Mill to bring you this festive Spring dessert. It’s perfect for Easter, baby showers, bridal showers, or any Spring celebration.

If there’s one flavor that I truly associate with Spring, it would be lemon. So, what better way to celebrate the arrival of spring than with some gluten free lemon squares?! And that was a rhetorical question because there isn’t a better way, duh.

Lemon bars have always been one of those understated desserts. Put them on an Easter dessert table covered with chocolate cupcakes, carrot cake, or even a coconut cake and the lemon bars probably wouldn’t be the first thing to go. It’s time to change that, it’s time the gluten free lemon squares had their time to shine. And this is the recipe to do that! If you’ve been searching for that perfect recipe and how to make the best lemon bars, this is the recipe for you! These lemon barsare a bittangy, but not too tangy! Because let’s be real, a true lemon bar wouldn’t really be a real lemon bar if it didn’t want to make you pucker just a little bit. That’s what makes lemon bars so good – that’s exactly why they’re special! These bars also have an amazing shortbread crust. I mean ah-mazing.

It’s buttery, crisp, and the perfect vehicle to transport that lemon custard. It’s thick enough so you can easily pick these up to eat them, no fork required! And let’s just have a moment of silence before we talk about that lemon filling because all hail that creamy, gooey, luscious lemon filling….This lemon custard filling is lemony thanks to the lemon juice and lemon zest.

It’s cool, refreshing, and makes you feel like you’re taking a bite out of Spring itself. It’s creamy, and thick but not too thick. I like my filling to be on the softer side because it just makes them SO good. While these squares are best stored in the fridge, I highly recommend letting them sit out at room temperature for 30 minutes to an hour before serving. They’ll have the perfect gooey factor and you know, it’s all about that lemon custard! And don’t dust them with the powdered sugar until right before serving too. That way, the powdered sugar won’t dissolve into the bars and disappear!

I used my favorite ready-made gluten free flour blend in this lemon bar recipe: Bob’s Red Mill 1-to-1 Baking Flour. After sending out my annual Reader Survey in my email newsletter, I found out that MANY of you alsouse this blend!

I love, love, big puffy heart love this flour and I’m so glad you do too! And FYI, Bob’salso has a new Paleo flour blend. My friend Kristen from A Mind “Full” Mom made some easy Paleo Lemon Chia Muffins with it and I can’t wait to try them!

That’s really going to be a fun flour to experiment with. But for now, I’m sticking to my beloved 1:1. I get such great results when baking with Bob’s gluten free flour blend and I even featured it as one of my gluten free pantry staples. It’s definitely a must-have flour blend if you do anygluten free baking.

Even if you don’t do a ton of gluten free baking, it’s great to have on hand for those timesyou want to bake something special for your gluten free friends or family members.

It’s even got the xanthan gum already in itto make it even easier for you! These gluten free lemon squares will be sure to put a smile on any lemon-lovers heart. They’re the perfect recipe for ushering in Spring.

Notes

If you use a flour blend that doesn't contain xanthan gum, add 1teaspoon when making the crust and 1/4 teaspoon when making the filling.

You can mix up the filling while the crust is baking. You do not need to cool the crust before you add the filling as you will be baking it again immediately after.

Store in an airtight container in the refrigerator up to 1 week.

FAQs

Why are my lemon squares runny? ›

Runny Lemon Bars are most likely caused from under baking. Make sure the filling no longer jiggles before taking it out of the oven. If your lemon bars are runny put them in the fridge to firm up as much as possible, keeping them cold will keep them firm.

What is the best way to cut lemon squares? ›

To cut, use the foil overhang to lift the baked square out of pan and onto a cutting board. Carefully loosen the foil from the edges of the crust, using a knife if necessary. Using a sharp knife, cut into squares or triangles. Use a fine sieve to dust the squares with Confectioners' sugar.

Why are my lemon bars upside down? ›

Set a timer for 5 minutes after pulling the crust from the oven to ensure it doesn't cool too much—if the shortbread is allowed to reach room temperature, the uncooked lemon curd will slip off the top and pool in the bottom of the dish, turning your lemon bars upside down (sounds bananas until it happens to you!).

How do you cut lemon bars without sticking to the knife? ›

I have found that a hot, wet, very sharp knife helps quite a bit. Also, make sure the bars are completely chilled before cutting.

What to do when lemon bars won't set? ›

Ratio of Liquid to Thickener: If the recipe doesn't have the right balance of eggs (which act as a thickener) to liquid (lemon juice), the filling won't set properly. Solution: Ensure your recipe has enough eggs to set the lemon mixture. A good rule of thumb is about 2 large eggs per 1/2 cup of lemon juice.

Do homemade lemon squares need to be refrigerated? ›

Lemon bars should be stored in an airtight container and refrigerated in order to prevent bacterial growth or foodborne illness. The filling in lemon bars is made with eggs and can become a breeding ground for bacteria if it's kept in the danger zone (between 41 and 153 degrees F).

How many lemons for 1 cup of juice? ›

How Much Juice Is in One Lemon? On average, there are 3 tablespoons of juice in one lemon. So, for a cup of fresh lemon juice, you would need 5 and a quarter lemons. Because some lemons are less juicy than others, it's safe to say you'll need 5 and a half lemons for a cup of lemon juice.

Why is there a crust on top of my lemon bars? ›

The crust forms when the sugar in the lemon bar mixture caramelizes and browns during baking, creating a slightly firm, crispy layer over the bars. The top crust isn't always visible, as we all enjoy sprinkling powdered sugar on top of the bars before serving.

How to keep lemon bars from sweating? ›

To avoid this, always cool lemon bars COMPLETELY before covering and storing in the fridge. Sometimes I actually cool them to room temperature, and then I put the pan in the fridge to cool for an hour or two before covering them with foil. This works quite well!

How to get lemon bars out of the pan? ›

Removing lemon bars from the pan - I recommend using parchment paper in the bottom of your pan. You can leave the ends out so that the entire pan of lemon bars can be lifted out of the pan, and then sliced into squares. Cutting your lemon bars - Make sure your bars are completely cool before slicing.

Why is my lemon pie runny? ›

The watery layer between the meringue and the filling (weeping) is usually caused by undercooking. This is where it is important to put your meringue onto hot filling so it can begin cooking right away.

Why is my lemon filling not thickening? ›

It's likely your measurements were off and you either added too much lemon juice or not enough egg. You may not have heated the lemon curd to the proper temperature. Using a thermometer is a great way to ensure that you are cooking the egg to the point of thickening – 170 degrees F.

Why is my lemon tart runny? ›

A runny lemon tart could be the result of two things: not cooking the filling long enough or not chilling the tart long enough. To know how long to cook the filling, you'll need an instant-read thermometer. The filling should reach 175 to 180 degrees Fahrenheit before it's pulled from the heat.

Why is my lemon butter runny? ›

Problem: My Lemon Curd is Too Runny

The curd wasn't cooked long enough to allow the egg to thicken, or not enough butter was added.
