How to Make Gluten-Free Lemon Bars

Start with the Crust

1. Begin by preheating your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving enough overhang on the sides to lift the bars out easily later.
2. In a large bowl, whisk together the gluten-free flour, powdered sugar, and salt. Stir in the melted butter until the mixture forms a soft, crumbly dough.
3. Press the dough evenly into the prepared baking pan, ensuring it reaches all edges and corners. Use a spatula or the back of a spoon to smooth it out.
4. Bake the crust for 15–18 minutes, or until it turns lightly golden around the edges. Set it aside to cool slightly while you prepare the filling.

Prepare the Lemon Filling

1. While the crust is baking, whisk together the eggs and granulated sugar in a medium-sized bowl. Beat until the mixture is smooth and slightly frothy.
2. Gradually add the gluten-free flour, lemon juice, and lemon zest, whisking until no lumps remain. The filling should have a smooth and uniform texture.
3. Once the crust has cooled slightly, pour the lemon filling over it, spreading it evenly to cover the entire surface.

Bake the Lemon Bars

1. Place the baking pan back into the oven and bake for 20–25 minutes. Check that the filling is set—it should no longer jiggle when the pan is gently shaken.
2. Remove the pan from the oven and allow the bars to cool completely at room temperature.

Chill and Slice

1. To achieve the best texture, refrigerate the cooled lemon bars for at least 2 hours. This step allows the filling to firm up, making it easier to cut cleanly.
2. Use the parchment paper overhang to lift the bars out of the pan. Place them on a cutting board and slice them into squares or rectangles using a sharp knife.

Add the Finishing Touches

Before serving, dust the tops of the bars with powdered sugar for a classic look. For extra flair, garnish with lemon slices or zest. Serve chilled for the best flavor and texture.

Pro Tips for Perfect Gluten-Free Lemon Bars

1. Use Fresh Lemons: Freshly squeezed lemon juice and zest are key to achieving a bright and zesty flavor. Bottled lemon juice doesn’t offer the same intensity.
2. Choose High-Quality Gluten-Free Flour: A blend that includes xanthan gum will give the crust the structure it needs to hold the filling.
3. Line the Pan with Parchment Paper: This makes it easier to remove the bars from the pan without breaking them.
4. Avoid Overbaking: Check the bars around the 20-minute mark to ensure the filling is set but not browned.
5. Chill Thoroughly Before Slicing: Refrigerating the bars makes them easier to cut and enhances their overall flavor.

Variations and Customizations

Add a Fruity Twist

• Berry Swirl: Swirl raspberry or blueberry puree into the filling before baking for a pop of color and flavor.
• Coconut Lemon Bars: Sprinkle shredded coconut on top of the bars after baking for a tropical touch.

Dairy-Free Option

• Replace the butter with a plant-based alternative to make the crust completely dairy-free without sacrificing flavor.

Experiment with Citrus Flavors

• Swap out the lemon juice and zest for lime or orange to create a different variation. You can also combine citrus fruits for a unique flavor profile.

FAQs About Gluten-Free Lemon Bars

Q: Can I use almond flour for the crust?

A: Yes, almond flour works well, but the texture will be slightly crumbly. Avoid using it in the filling as it doesn’t provide the same thickening properties.

Q: How can I prevent the filling from cracking?

A: Avoid overbaking the bars and ensure the filling is evenly whisked before pouring it over the crust.

Q: Can I make these bars vegan?

A: Substitute the butter with a plant-based option and use an egg substitute like flaxseed meal. Note that the texture may vary slightly.

Q: Why does my filling have bubbles?

A: Over-whisking can introduce air bubbles into the filling. Mix gently to avoid this issue.
