Ingredients You’ll Need

All-Purpose Flour: Used for both the crust and filling structure. Gives the bars their sturdy base.
Butter: Unsalted is best here—provides a rich, crumbly texture in the crust.
Granulated Sugar: Sweetens both the crust and the lemon filling.
Dried Culinary Lavender: Adds that delicate floral aroma and a subtle, herby flavor. Make sure to use food-grade lavender!
Lemons: You’ll need both juice and zest. They bring the tart, zippy brightness that makes lemon bars irresistible.
Eggs: Essential for setting the lemon filling—use fresh eggs for the best texture and flavor.
Cornstarch: Helps stabilize the filling and gives it that smooth, silky texture.
Powdered Sugar: For a sweet finishing dust on top. It also makes them look beautifully bakery-worthy.

Variations

Herbaceous Twist: Swap out the lavender for rosemary or thyme for a more earthy spin.
Gluten-Free Option: Use a gluten-free flour blend for the crust—just make sure it’s one meant for baking.
Extra Citrus: Add a touch of orange or lime zest to the lemon mixture for a more complex citrus profile.
Creamier Filling: Mix in a bit of mascarpone or cream cheese for a creamier texture and a hint of richness.

How to Make Lavender Lemon Bars

Step 1: Prep the Crust

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper. In a bowl, mix together flour, sugar, and cold butter until the mixture resembles coarse crumbs. Press it firmly into the bottom of the prepared dish and bake for about 15-18 minutes, or until lightly golden.

Step 2: Infuse the Lavender

While the crust bakes, warm the lemon juice gently on the stove and stir in the dried lavender. Let it steep for 5-10 minutes, then strain to remove the buds. This quick infusion allows the floral flavor to bloom without being overwhelming.

Step 3: Make the Lemon Filling

In a large bowl, whisk together the eggs, sugar, lemon zest, infused lemon juice, cornstarch, and a touch of flour. Whisk until smooth and slightly frothy.

Step 4: Bake Again

Pour the lemon mixture over the warm crust and return to the oven. Bake for another 20-25 minutes, or until the filling is set and just barely jiggles in the center.

Step 5: Cool and Finish

Let the bars cool completely, then refrigerate for at least an hour. Dust with powdered sugar before slicing into neat squares or rectangles.

Pro Tips for Making the Recipe

Chill Before Slicing: For clean, sharp edges, don’t skip the refrigeration step. It firms up the filling and makes cutting much easier.
Don’t Overdo the Lavender: A little goes a long way—too much and it can taste soapy. If you’re unsure, start small and adjust next time.
Use Fresh Lemons: Bottled juice won’t cut it here. Fresh lemon juice and zest are what give these bars their bold, bright flavor.
Strain the Filling: For an ultra-smooth texture, pour the lemon mixture through a fine-mesh sieve before baking.

How to Serve

These bars are wonderful all on their own, but a few thoughtful additions can elevate the experience even more:

Garnish:

Sprinkle with a touch of lemon zest or a few lavender buds for a decorative, fragrant finish.

Pairings:

Serve with a cup of Earl Grey tea or a glass of sparkling water with a lemon wedge—both enhance the floral and citrus notes beautifully.

Dessert Plate:

Plate them with a scoop of vanilla bean ice cream or a dollop of whipped cream for a more indulgent treat.

Make Ahead and Storage

Storing Leftovers

Store lavender lemon bars in an airtight container in the refrigerator for up to 5 days. The flavors actually deepen after a day or two, so they’re even better as leftovers.

Freezing

Yes, they freeze beautifully! Wrap individual bars in parchment and store in a freezer-safe bag or container. Freeze for up to 2 months.

Reheating

These bars are best enjoyed cold or at room temperature. No need to reheat—just let them thaw in the fridge if frozen.

FAQs

Can I use fresh lavender instead of dried?
Yes, but be careful with the amount—fresh lavender is more potent. Use about half the quantity and chop it finely before infusing it in the lemon juice.

What if I don’t have cornstarch?
You can substitute with the same amount of all-purpose flour. The filling might be slightly less silky, but it will still hold up well.

Can I double the recipe?
Absolutely! Just use a 9×13-inch baking pan and adjust the baking time slightly—add 5-10 more minutes and check the filling’s doneness.

Why is my filling runny?
It might need more time to bake or wasn’t fully chilled before cutting. Make sure the center only has a slight jiggle before removing from the oven, and always cool completely.
