gluten free lemon bars Ingredients
For the Crust:
- 1 ½ cups gluten-free all-purpose flour blend (with xanthan gum)
- ½ cup powdered sugar
- ¼ teaspoon salt
- ¾ cup unsalted butter, cold and cubed
For the Lemon Filling:
- 4 large eggs
- 1 ½ cups granulated sugar
- ⅓ cup gluten-free all-purpose flour blend
- ½ cup fresh lemon juice (about 3-4 lemons)
- 1 tablespoon lemon zest
- ¼ teaspoon salt
For Topping:
- Powdered sugar for dusting
Instructions
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. Lightly grease the parchment with butter or cooking spray.
Step 2: Make the Crust
In a large mixing bowl, whisk together the gluten-free flour, powdered sugar, and salt. Add the cold cubed butter and use a pastry cutter or your fingers to work it into the flour mixture until it resembles coarse crumbs. Press the mixture evenly into the bottom of your prepared pan.
Step 3: Bake the Crust
Bake the crust for 18-20 minutes, or until it’s lightly golden around the edges. Remove from the oven and let it cool slightly while you prepare the filling. Keep the oven on.
Step 4: Make the Lemon Filling
In a medium bowl, whisk together the eggs and granulated sugar until well combined. Add the gluten-free flour, lemon juice, lemon zest, and salt. Whisk until the mixture is smooth and no lumps remain.
Step 5: Pour and Bake
Pour the lemon filling over the warm crust, spreading it evenly to the edges. Return the pan to the oven and bake for 22-25 minutes, or until the filling is set and no longer jiggles in the center.
Step 6: Cool Completely
Remove the pan from the oven and let the bars cool completely at room temperature. For best results, refrigerate for at least 2 hours before cutting. This helps the bars set properly and makes them easier to slice.
Step 7: Cut and Serve
Use the parchment paper overhang to lift the bars out of the pan. Cut into 16 squares using a sharp knife (wipe the knife clean between cuts for neat edges). Dust generously with powdered sugar before serving.

Tips, Variations & Storage
Substitutions & Variations:
- Dairy-Free Option: Use vegan butter or coconut oil in place of regular butter for both the crust and filling.
- Extra Tangy: Add an extra tablespoon of lemon juice and increase the zest to 2 tablespoons.
- Lime Bars: Swap lemon juice and zest for lime to make gluten-free lime bars instead.
- Gluten-Free Flour: Make sure your flour blend contains xanthan gum. If it doesn’t, add ½ teaspoon to the crust and ¼ teaspoon to the filling.
Make-Ahead Advice:
You can prepare the crust up to 1 day ahead. Bake it, let it cool, cover tightly and refrigerate. Add the filling and bake when you’re ready.
Storage Tips:
Store leftover gluten free lemon bars in an airtight container in the refrigerator for up to 5 days. You can also freeze them for up to 3 months—just wrap individual bars in plastic wrap, then place in a freezer bag. Thaw in the fridge overnight before serving.
Serving Ideas:
These bars are delicious on their own, but you can serve them with a dollop of whipped cream, fresh berries, or a Chocolate Banana Ice Cream for an extra-special dessert.
FAQs About gluten free lemon bars
Can I use regular all-purpose flour instead of gluten-free flour?
Yes, if you’re not following a gluten-free diet, you can substitute regular all-purpose flour in equal amounts. The texture will be slightly different but still delicious.
Why is my lemon filling runny?
Make sure you bake the filling long enough it should be set and not jiggly in the center. Also, allow the bars to cool completely and chill in the fridge before cutting, as this helps them firm up.
Can I use bottled lemon juice?
Fresh lemon juice is highly recommended for the best flavor. Bottled lemon juice often has a slightly bitter or artificial taste that can affect the final result.
Do I need to use a gluten-free flour blend with xanthan gum?
Yes, xanthan gum helps bind the ingredients together in gluten-free baking. If your flour blend doesn’t include it, add ½ teaspoon to the crust mixture and ¼ teaspoon to the filling.
How do I know when the bars are done baking?
The filling should be set and slightly golden on top. It may still have a slight jiggle in the very center, but it will firm up as it cools.

Notes
- Gluten-Free Flour: Use a gluten-free all-purpose flour blend that contains xanthan gum (such as Bob’s Red Mill 1-to-1 Baking Flour or King Arthur Measure for Measure). If your blend doesn’t include xanthan gum, add ½ teaspoon to the crust and ¼ teaspoon to the filling.
- Fresh Lemon Juice: Always use fresh lemon juice for the best flavor. Bottled lemon juice has a different taste and can make the bars taste artificial.
- Cooling Time: Cooling completely and refrigerating is essential for clean cuts. The filling needs time to set properly.
- Clean Cuts: Wipe your knife clean between each cut for neat, professional-looking bars.
- Storage: Store in an airtight container in the refrigerator for up to 5 days. Can be frozen for up to 3 months.
- Make Ahead: The crust can be baked 1 day ahead. Cover and refrigerate, then add filling and bake when ready.
