Key Ingredients & Substitutions
Butter: Unsalted butter is best since you control the salt level. If you’re out, coconut oil can make a great substitute, adding a slight coconut flavor.
Flour: All-purpose flour gives the crust structure. If you need a gluten-free option, almond flour or a gluten-free baking blend typically work well in similar recipes.
Culinary Lavender: Dried culinary lavender is essential for the flavor. If you can’t find it, you can skip this ingredient or use a tiny amount of lavender extract, but be careful not to overpower the lemon.
Lemon Juice: Freshly squeezed lemon juice is crucial for bright flavor. Bottled lemon juice can work in a pinch, but fresh makes a big difference!
Eggs: Large eggs are needed for the filling. If you want an egg-free version, you could experiment with a flaxseed or chia seed mixture, but the texture will change.
How Can I Ensure My Lemon Filling Is Smooth and Set?
Getting the lemon filling just right is key to these bars. Here’s how to avoid lumps and ensure it sets well:
- Whisk the eggs and sugar first until smooth. Be sure to mix well before adding other ingredients.
- When you add the lemon juice and lavender syrup, do it gradually while continuing to whisk. This helps combine it evenly.
- Don’t skip the baking time! Make sure the filling is set in the middle. It will continue to firm up as it cools.

How Much Time Will You Need?
This delicious recipe will take you about 30 minutes of prep time and an additional 40-45 minutes for baking and cooling. So, plan for around 1 hour and 15 minutes total. This includes making your crust, preparing the lavender syrup, whipping up the lemon filling, and letting everything cool before you enjoy your tasty bars!
Step-by-Step Instructions:
1. Preparing the Lavender Simple Syrup:
Start by making the lavender simple syrup, as it can steep while you prepare the other components. In a small saucepan, combine water, sugar, and dried lavender. Bring it to a boil over medium heat, then reduce the heat and let it simmer for 5 minutes. After that, remove it from the heat and let it steep for 15 minutes to infuse the flavor. Once steeped, strain the syrup to remove the lavender bits, and set it aside for later use.
2. Making the Crust:
Now, let’s prep the crust! Preheat your oven to 350°F (177°C). Line a 9×13 inch baking pan with parchment paper, making sure to leave some overhang so you can easily lift the bars out later. In a mixing bowl, cream together the softened butter and granulated sugar until it’s light and fluffy. Then, add the flour and salt, mixing until just combined and a dough forms. Press this dough evenly into the bottom of your prepared pan. Bake in the oven for 15-18 minutes, or until the edges are just lightly golden.
3. Preparing the Lemon Filling:
While the crust is baking, let’s get started on the lemon filling. In a large bowl, whisk together the eggs, granulated sugar, and flour until it’s smooth. Then, stir in the freshly squeezed lemon juice, lemon zest, and 1 tablespoon of the lavender simple syrup you prepared earlier. Once the mixture is combined well, pour it over the hot baked crust.
4. Baking the Lemon Bars:
Return the pan to the oven and bake for another 20-25 minutes. You’ll know they’re done when the filling is set and doesn’t jiggle when you gently shake the pan. When they’re finished baking, remove them from the oven and let them cool completely in the pan on a wire rack.
5. Finishing Touches:
Once the bars are completely cool, you can lift them out of the pan using the parchment overhang. Dust the top generously with powdered sugar for that perfect finishing touch! If you want, you can add fresh or dried lavender flowers as a pretty garnish. Finally, cut into squares and enjoy your delightful Lavender Lemon Bars!
Enjoy your fragrant and tangy Lavender Lemon Bars!
Can I Use Fresh Lavender Instead of Dried?
Yes, you can use fresh lavender! Just double the amount since fresh herbs are less concentrated than dried ones. Make sure the lavender is culinary-grade and safe for consumption.
How Can I Adjust the Sweetness?
If you prefer your lemon bars less sweet, you can reduce the amount of granulated sugar in both the crust and filling by up to 1/2 cup. Just be mindful that this may also affect the texture slightly!
What If I Don’t Have Parchment Paper?
If you don’t have parchment paper, you can lightly grease the baking pan with butter or cooking spray to prevent sticking. Just be sure to let the bars cool completely before trying to remove them!
How Do I Store Leftover Lemon Bars?
Store any leftovers in an airtight container in the fridge for up to 4 days. For longer storage, you can freeze them for up to 3 months. Make sure to wrap them tightly in plastic wrap and foil before freezing! Just thaw in the fridge before serving.
