Ingredients You’ll Need

• 1½ cups gluten-free flour (222g): This is the base for our crust. I recommend a blend designed for baking to ensure the best texture. Look for options that contain xanthan gum for added stability.
• ½ cup granulated sugar (100g): Sweetens the crust while complementing the tartness of the filling.
• ½ cup salted butter (113g), cold and cut into pieces: Adds richness and creates a flaky crust. Dairy-free butter works beautifully if you need a non-dairy option.
• 2 tablespoons water (28 ml): Helps bind the crust together; cold water is key!
• 1½ cups granulated sugar (300g): This is for the luscious lemon filling.
• ½ cup lemon juice (118 ml): Freshly squeezed juice is vital for that vibrant tartness! Meyer lemons offer a sweeter variation if you prefer.
• 2 tablespoons grated lemon zest (12g): Enhances the lemon flavor, so don’t skip the zest! Feel free to add more for an extra punch.
• 4 large eggs: These bind the filling and give it a dreamy texture.
• ¼ cup gluten-free flour (37g): Helps stabilize the filling, ensuring it sets perfectly.
• Powdered sugar (optional): A light dusting on top makes for a lovely presentation and extra sweetness.

How to Make Gluten Free Lemon Bars

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Prepare your 9×9-inch baking pan by spraying it with nonstick spray. I love to line mine with foil as well—this makes lifting the bars out much easier!

2. Make the Crust: In a medium bowl, combine the 1½ cups gluten-free flour and ½ cup granulated sugar. Using a fork or a knife, cut in the cold pieces of butter until you achieve a crumbly mixture. Gradually mix in the water until the dough comes together. Press this mixture evenly into the bottom of your prepared pan.

3. Bake the Crust: Place the pan in the oven and bake for about 25 minutes, or until the crust is slightly golden and set. You want it to be firm and have a lovely color.

4. Prepare the Filling: While the crust bakes, take a larger bowl and stir together the 1½ cups granulated sugar, freshly squeezed lemon juice, 2 tablespoons of lemon zest, and 4 lightly beaten eggs. Mix well until everything is combined and smooth. Then, fold in ¼ cup gluten-free flour, ensuring no lumps remain.

5. Combine: Once the crust is out of the oven and still warm, pour the lemon filling over the hot crust. This helps meld the flavors beautifully.

6. Bake Again: Return the pan to the oven. Bake for another 22-26 minutes or until the filling is set in the middle but still has a slight jiggle when you gently shake the pan; it will continue to set as it cools.

7. Cool and Serve: Allow the bars to cool on the counter for at least 2 hours. Once cooled, you can cut them into squares. For a delightful finish, sprinkle some powdered sugar on top before serving.

Storing & Reheating

These lemon bars are best stored in an airtight container at room temperature for up to 3 days for maximum freshness. If you need to keep them longer, they can chill in the refrigerator for up to a week. Just make sure to place them in a container that prevents them from drying out. For longer storage, you can freeze them for up to 3 months. When ready to enjoy, thaw them in the refrigerator overnight or let them sit at room temperature for a bit. You might notice a slight change in texture, but a quick dusting of powdered sugar can bring back that charming look!

Chef’s Helpful Tips

• Check Your Flour: Not all gluten-free flours are created equal! Make sure to use one that’s meant specifically for baking to maintain the right texture.
• Don’t Overmix the Filling: When combining the filling ingredients, mix just until smooth to avoid a rubbery texture.
• Fresh Is Best: Using fresh lemon juice and zest makes a significant difference in flavor. Bottled lemon juice doesn’t have the same brightness.
• Cut Evenly: Use a sharp knife and wipe it clean between cuts for perfectly neat squares.
• Add More Zest: If you’re a citrus lover, feel free to add extra lemon zest for a bolder flavor in the filling.

These gluten-free lemon bars are not just a delicious treat—you can feel good sharing them with friends and family, knowing they’ll love each and every bite! I encourage you to experiment with adding different toppings, like fresh berries or whipped cream, for an extra layer of flavor. Your kitchen will smell divine, and your taste buds will thank you.

Recipe FAQs

Can I use regular flour in this recipe?

Yes, you can use regular all-purpose flour instead of the gluten-free flour if you don’t need a gluten-free option. Just substitute it in the same measurements, and you’ll still have delicious lemon bars!

How do I know when the lemon bars are ready to come out of the oven?

Look for a slight jiggle in the center of the filling; it should not be completely firm but have a soft set. The edges might be slightly puffed and will continue to set as they cool.

Can these bars be made ahead of time?

Absolutely! In fact, they taste even better the next day as the flavors have time to meld together. You can make them a day ahead and store them in the fridge until you’re ready to serve.

What can I do if my lemon bars don’t set?

If your bars don’t set properly, it may be due to underbaking. Ensure you bake them until they’re just firm in the center but still have that slight jiggle. If they still don’t set after chilling, you might need to add a bit more flour next time.
