Ingredients

- ½ teaspoon kosher salt
- Zest of 1 large lemon
- 9 tablespoons (126 g) unsalted butter, melted and cooled

- 1 cup (200 g) granulated sugar
- ¾ teaspoon baking powder
- ⅔ cup (5.33 fluid ounces) freshly squeezed lemon juice, juice of 4 to 5 lemons
Instructions
- Preheat your oven to 325°F. Grease an 8-inch square baking pan, line with criss-crossed pieces of parchment paper that overhang the sides, and grease the parchment paper. Set the pan aside.
Make the crust.
- In a medium-sized bowl, combine 1 cup (140 g) of the flour, confectioners’ sugar, salt and lemon zest and whisk to combine, breaking up any clumps of lemon zest.
- Add the butter and mix with a fork until well-combined. Press the mixture into the bottom of the prepared baking dish in an even layer.
- Place the baking dish in the center of the preheated oven and bake for about 15 minutes or until firm.
- Remove from the oven and allow to cool briefly.
Make the custard layer.
- In a medium-sized bowl, place the eggs, granulated sugar, baking powder, lemon juice and remaining 2/3 cup (93 g) flour, whisking vigorously to combine after each addition. Pour the custard mixture into the baked crust.
Bake the bars.
- Return the pan to the center of the oven. Bake until just set (about 25 minutes).
- The custard is set when it does not jiggle more than a tiny bit in the center when the pan is shaken gently back and forth.
- Remove the pan from the oven and allow to cool in the pan for about 20 minutes.
Chill the bars.
- Place in the refrigerator to chill until firm, about 2 hours and up to overnight.
- Remove the bars from the pan by running a butter knife or thin spatula around the perimeter of the baking dish, and then lifting the bars out of the pan by the overhung pieces of parchment paper.
- Dust lightly with confectioners sugar, and slice into 9 or 12 squares with a large knife. Serve chilled.

Pro Tips for the Best Gluten Free Lemon Bars
Use Parchment for Easy Removal
One trick to perfect results? Always line your pan with parchment paper. It prevents sticking and helps lift the bars cleanly once they’re set.
Measure Accurately
In this gluten free lemon bars recipe, weighing your gluten free flour is essential. Too much flour leads to a dry crust, while too little can cause soggy bottoms. Use a scale for best results.
Give the Bars Time to Chill
Patience pays off. Let your bars cool, then refrigerate for at least 2 hours. This step helps the lemon custard layer set properly and makes slicing easier.
Using Fresh Lemons vs Bottled Juice
Always Choose Fresh Lemon Juice
In this gluten free lemon bars recipe, fresh lemons aren’t optional they’re essential. Bottled juice lacks the bright, sharp citrus flavor that fresh juice delivers. Plus, many bottled versions have additives that dull the overall taste.
Zest Makes a Difference
Lemon zest adds a concentrated citrus punch. It infuses both the crust and custard with pure lemon oil from the skin something bottled juice just can’t match.
If you want true flavor, always zest before you juice. For extra brightness, try Meyer lemons when in season.

Common Problems & Solutions for Lemon Bars
Why Do Lemon Bars Turn Out Rubbery?
A rubbery texture usually means overbaking. This gluten free lemon bars recipe depends on a soft-set custard. Bake just until the center jiggles slightly. If it’s firm in the oven, it’ll be stiff after cooling.
Glass or Metal Pan: Which Is Better?
Use a light-colored metal pan. Glass takes longer to heat, which can affect how evenly the bars bake. Metal pans ensure the crust stays crisp and the filling sets properly.

FAQs About Gluten Free Lemon Bars Recipe
Can I use bottled lemon juice for lemon squares?
Technically, yes but it’s not recommended. Bottled lemon juice lacks the brightness and complexity of fresh lemons. For the best results in this gluten free lemon bars recipe, always use freshly squeezed lemon juice and zest. It dramatically enhances both the flavor and aroma, taking the dish to the next level.
Why are my lemon bars rubbery?
Rubbery lemon bars are usually a sign of overbaking or too much flour. In this gluten free lemon bars recipe, it’s important to bake until the filling slightly jiggles not until it’s firm. Also, weigh your flour instead of scooping to avoid a dense texture.
Is it better to bake lemon bars in a glass or metal pan?
A light-colored metal pan is best. It heats evenly and helps the crust bake properly. Glass takes longer to heat and can lead to overcooked edges and undercooked centers in your gluten free lemon bars recipe.
Are Trader Joe’s lemon bars gluten free?
