Ingredients

For the Lavender-Infused Shortbread Crust

• 170 g (1 ½ sticks) unsalted butter, melted: Provides richness and binds the crust.
• 200 g (1 ½ cups) gluten-free all-purpose flour blend (containing xanthan gum): Provides structure for the crust. Use a quality blend for best results.
• 75 g (½ cup) powdered sugar: Adds sweetness and tenderness to the crust.
• ¼ teaspoon fine sea salt: Balances the sweetness and enhances the flavors.
• 1 ½ teaspoons culinary dried lavender buds: Infuses the crust with a subtle floral aroma.

For the Candied Lemon Swirl

• 1 large lemon, very thinly peeled (avoiding white pith) and julienned: Provides the textural element for the swirl.
• 100 ml (½ cup) water: Used to create the simple syrup for candying.
• 100 g (½ cup) granulated sugar: Sweetens the lemon peel.

For the Lavender Lemon Filling

• 4 large eggs: Forms the custard base and provides richness.
• 200 g (1 cup) granulated sugar: Sweetens the tart lemon juice.
• 120 ml (½ cup) freshly squeezed lemon juice (from 2-3 lemons): Provides the bright, essential lemon flavor. Freshly squeezed juice makes a significant difference.
• 2 teaspoons culinary dried lavender buds: Infuses the filling with floral notes.
• 1 tablespoon gluten-free all-purpose flour blend: Helps thicken the filling.
• ¼ teaspoon fine sea salt: Balances the sweetness.
• Zest of 1 large lemon, finely grated (avoiding white pith): Adds intense lemon aroma to the finished filling.

For Serving Garnish

• 30 g (¼ cup) powdered sugar: For dusting the finished bars.

Instructions

1. Prep the Pan and Oven

   Preheat the oven to 175°C (350°F). Lightly grease a 23×33 cm (9×13 inch) baking pan and line it with parchment paper. Leave an overhang on the longer sides so you can easily lift the bars out later.

2. Make the Lavender Shortbread Crust

   In a medium bowl, whisk together the GF flour blend, 75 g powdered sugar, and ¼ teaspoon fine sea salt. Pour in the melted butter and 1 ½ teaspoons dried lavender buds. Mix until the mixture forms a moist, crumbly dough. Press the dough evenly into the prepared pan. Bake for 18-20 minutes, or until the edges are lightly golden. Remove from oven and set aside.

3. Prepare the Candied Lemon Swirl

   While the crust bakes, place the julienned lemon peel in a small saucepan. Cover with cold water, bring to a boil, then immediately drain. Repeat this blanching process twice more to remove any bitterness from the lemon’s pith. After the third drain, return the peel to the saucepan with 100 ml water and 100 g granulated sugar. Simmer over medium-low heat for 10-15 minutes, until the peel becomes translucent and the syrup thickens. Drain the peel, reserving a few very fine strands for garnish. Finely chop the remaining candied lemon peel for the swirl.

4. Infuse and Cook the Lavender Lemon Filling

   In a heatproof bowl, whisk together the eggs, 200 g granulated sugar, 120 ml lemon juice, 2 teaspoons dried lavender buds, 1 tablespoon GF flour, and ¼ teaspoon fine sea salt. Place the bowl over a saucepan of simmering water (bain-marie), ensuring the bottom of the bowl does not touch the water. Whisk continuously for 5-7 minutes, until the mixture thickens slightly and reaches 70°C (160°F). I always use a fine-mesh sieve here; it’s crucial for getting that silky texture without a trace of grittiness from the lavender buds. Remove from heat, stir in the lemon zest, then immediately strain the mixture through a fine-mesh sieve into a clean bowl to remove the lavender buds and any egg solids.

5. Assemble and Bake the Bars

   Pour the warm, strained lemon filling evenly over the par-baked crust. Gently drop spoonfuls of the chopped candied lemon peel evenly over the filling. Using a skewer or the tip of a knife, swirl the candied lemon peel into the filling to create distinct ribbons and patterns. Return the pan to the oven and bake for 20-25 minutes, or until the center is just set but still has a slight jiggle. To avoid overbaking these gluten free lemon bars, pull them out when the center still wiggles slightly when shaken gently; overbaking causes the filling to crack and become tough.

6. Chill for Clean Cuts

   Let the bars cool completely in the pan on a wire rack for at least 2 hours at room temperature. Once cooled, transfer the pan to the refrigerator and chill for at least 4 hours, or preferably overnight, before cutting. Chilling is essential for clean slices and a firm set for these gluten free lemon bars.

7. Cut and Serve

   Once thoroughly chilled, use the parchment paper overhang to lift the entire slab of bars from the pan. Transfer to a cutting board and trim the edges for a neat presentation, then cut into desired bar sizes. Dust generously with 30 g powdered sugar through a fine-mesh sieve, then gently place one or two very fine strands of the reserved candied lemon peel alongside each bar for an elegant finish.

Making and Storing Gluten-Free Lemon Bars

When making this gluten free lemon bars recipe ahead of time, be sure to store them properly to maintain texture and flavor. They make excellent meal prep desserts or a quick treat for a special occasion.

• Make ahead instructions: The bars can be made 1-2 days in advance. Store in the refrigerator, tightly wrapped, to maintain freshness and texture.
• Freezing instructions: To freeze, place uncut, chilled bars in an airtight container between layers of parchment paper. Freeze for up to 3 months. Thaw overnight in the refrigerator before dusting and serving.
• Serving tips: These bars are best served chilled. The filling will soften at room temperature, making them slightly messy if left out too long.

Pro Tips for Perfect Gluten-Free Lemon Bars

A few expert tips can ensure your bars turn out perfectly smooth and vibrant every time. Avoid the most common mistakes by following these key steps for this family-friendly gluten free lemon bars recipe.

• Doneness Check: The most common mistake is overbaking. The filling should still have a slight jiggle in the center when removed from the oven. Overbaking causes a tough texture and cracks on the surface.
• Blanching the Peel: Don’t skip the blanching process for the candied lemon peel. This step removes bitterness from the lemon’s pith and ensures the final flavor is sweet and clean.
• Straining the Custard: Always strain the filling mixture after cooking in the bain-marie. This removes the lavender buds and any small bits of scrambled egg, resulting in a perfectly smooth, silky custard filling.

FAQs

Can I make this with regular all-purpose flour instead of gluten-free?

Yes, you can substitute 1:1 with standard flour for both the crust and filling. The overall result will be very similar, though the gluten-free crust texture will be slightly different from a traditional one.

Is culinary lavender necessary?

Yes, ensure you use culinary-grade lavender. Other types can contain pesticides and are not safe for consumption. Culinary lavender is specially grown for eating and provides the best aroma.

Why did my filling crack on top?

Cracking is typically caused by overbaking. The center should be set but still slightly jiggly when you remove it from the oven, as it will continue to cook as it sets. Overbaking results in a tough texture.

How do I get clean cuts?

Chilling is essential. Do not attempt to cut the bars until they have chilled for at least 4 hours or overnight. For extra clean cuts, I use a sharp knife heated in hot water and wiped dry between slices.

Can I use lemon extract instead of fresh lemon juice?

Freshly squeezed lemon juice provides a much brighter, more natural flavor profile that balances the sweetness and lavender; extract often tastes artificial and should be avoided here for the best gluten free lemon bars recipe.

How long do these keep in the refrigerator?

Stored properly in an airtight container, these gluten free lemon bars stay fresh for 3-4 days. This makes them great for healthy eating and meal prep throughout the week.

Conclusion

These gluten free lemon bars are more than just a dessert; they are a sophisticated treat that brings a touch of elegance to any table. The combination of tart lemon, floral lavender, and sweet candied peel makes this recipe truly memorable.
