Lavender Lemon Bars

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

For the Vegan Shortbread Crust:

½ cup vegan butter, melted

¼ cup granulated sugar

1 cup all-purpose flour

¼ teaspoon salt

For the Lavender Lemon Filling:

1 ½ cups granulated sugar

1 teaspoon dried culinary lavender

2 teaspoons lemon zest

¾ cup freshly squeezed lemon juice

1 ¼ cups unsweetened soy milk, oat milk, coconut milk, or almond milk

6 tablespoons cornstarch

1 tiny pinch turmeric

For Garnishing:

Powdered sugar, for dusting

Dried culinary lavender, optional for garnish

Directions

Making these Lavender Lemon Bars involves preparing the lavender sugar, baking the shortbread crust, cooking the creamy lemon filling, and chilling everything until firm. I follow these steps to get consistently delicious results.

Prepare the Lavender Sugar:

I start by adding 1 ½ cups of granulated sugar and 1 teaspoon of dried culinary lavender to a food processor.

I pulse the mixture for approximately 20 seconds, until the lavender is finely ground and evenly distributed throughout the sugar.

This step helps release the lavender's delicate aroma while preventing large pieces of dried flowers from affecting the filling's smooth texture. I set the lavender sugar aside until needed.

Preheat the Oven and Prepare the Pan:

I preheat my oven to 350°F (175°C).

Next, I line an 8x8-inch or 9x9-inch baking pan with parchment paper, leaving some overhang on the sides.

I find the parchment paper especially helpful because it allows me to lift the finished lemon bars out of the pan without damaging their delicate filling.

Make the Shortbread Crust:

In a medium mixing bowl, I combine the melted vegan butter, ¼ cup granulated sugar, and salt.

I stir until everything is well incorporated, then add the all-purpose flour.

I continue mixing until a thick, slightly crumbly dough forms.

Next, I transfer the dough to the prepared baking pan and press it firmly into an even layer. I make sure to cover the entire bottom of the pan so every bar has a consistent crust.

Bake the Crust:

I place the pan in the preheated oven and bake the crust for approximately 18 minutes.

I look for edges that are very lightly golden while the center remains pale.

Once baked, I remove the crust from the oven and set it aside while preparing the filling.

I avoid overbaking because I want the crust to remain tender rather than becoming too hard.

Prepare the Lemon-Lavender Filling:

In a medium saucepan, I combine the prepared lavender sugar, lemon zest, freshly squeezed lemon juice, plant-based milk, cornstarch, and a tiny pinch of turmeric.

I whisk everything thoroughly while the mixture is still cold, making sure the cornstarch dissolves completely.

I find this important because undissolved cornstarch can create lumps in the finished lemon filling.

Cook the Filling Until Thickened:

I place the saucepan over medium-high heat and cook the mixture, whisking frequently.

As the filling heats, it gradually thickens and becomes creamy.

Once it begins bubbling and reaches a thick, pudding-like consistency, I immediately remove the saucepan from the heat.

I avoid cooking it longer than necessary because excessive cooking can affect the filling's final texture.

Assemble the Lavender Lemon Bars:

While the filling is still warm, I pour it over the baked shortbread crust.

I use a spatula to spread the filling evenly, making sure it reaches all four corners of the pan.

I then allow the assembled bars to cool at room temperature for approximately 30 minutes.

Chill Until Firm:

After the initial cooling period, I transfer the pan to the refrigerator.

I refrigerate the bars for 1 to 2 hours, or overnight, until the filling is completely set.

I personally prefer chilling them overnight whenever possible because the extra time helps the filling become firmer and makes slicing easier.

Slice and Garnish:

Once the bars are fully chilled, I lift them out of the pan using the parchment paper overhang.

I place them on a cutting board and use a sharp knife to cut them into 12 equal portions.

For cleaner slices, I wipe the knife between cuts.

Finally, I dust the bars generously with powdered sugar and add a small sprinkle of dried culinary lavender, if desired.

I serve these Lavender Lemon Bars chilled for the best texture and flavor.

Servings and Timing

Variations

One of my favorite things about this recipe is how easily I can customize it with different flavors and ingredients.

Extra-Lemony Lavender Bars:

When I want a stronger citrus flavor, I add an extra teaspoon of fresh lemon zest to the filling. I find this enhances the lemon aroma without introducing additional liquid that could affect the texture.

Gluten-Free Lavender Lemon Bars:

For a gluten-free version, I replace the all-purpose flour in the crust with a good-quality gluten-free all-purpose flour blend suitable for baking.

I make sure the blend contains appropriate binding ingredients so the crust holds together after baking.

Coconut Lavender Lemon Bars:

I sometimes use unsweetened coconut milk instead of soy or oat milk for a subtle coconut flavor.

I especially enjoy this variation because coconut pairs beautifully with lemon and lavender, creating a slightly tropical twist.

Raspberry Lavender Lemon Bars:

For a fruity variation, I add a thin layer of thick raspberry compote between the baked crust and lemon filling.

I love how the tart raspberries complement the citrus and floral notes. I keep the layer thin to avoid making the bars overly soft.

Orange Lavender Bars:

When I want a softer citrus flavor, I replace some of the lemon juice with freshly squeezed orange juice and add orange zest.

I find this variation slightly sweeter and more mellow, while the lavender remains pleasantly aromatic.

Reduced Lavender Flavor:

If I prefer a more subtle floral taste, I reduce the dried culinary lavender from 1 teaspoon to ½ teaspoon.

I find this particularly useful when serving guests who are unfamiliar with lavender-flavored desserts.

Storage/Reheating

Proper storage helps preserve the smooth filling and tender shortbread crust. Since these bars contain a creamy plant-based filling, I always keep them refrigerated.

Refrigerating:

I place leftover Lavender Lemon Bars in an airtight container and store them in the refrigerator for up to 4 days.

If I stack the bars, I separate the layers with parchment paper to prevent sticking.

I prefer adding powdered sugar immediately before serving because it can dissolve into the moist filling during storage.

Freezing:

For longer storage, I freeze the bars without powdered sugar or lavender garnish.

I arrange them in a single layer until firm, then transfer them to a freezer-safe container with parchment paper between layers.

I keep them frozen for up to 2 months for the best quality.

When I am ready to serve them, I thaw the bars overnight in the refrigerator.

Reheating:

I do not recommend reheating these Lavender Lemon Bars because they are designed to be served chilled.

Heating can soften the cornstarch-thickened filling and make the bars lose their clean shape.

Instead, I remove them from the refrigerator just before serving, or let them sit at room temperature for about 5 to 10 minutes if I prefer a slightly softer texture.

FAQs

Can I make Lavender Lemon Bars without culinary lavender?

Yes, I can easily make these bars without lavender. I simply omit the dried culinary lavender and follow the remaining recipe as written.

The result is a classic vegan lemon bar with a bright citrus flavor and creamy texture. I sometimes add a little extra lemon zest when leaving out the lavender.

Why didn't my Lavender Lemon Bars set properly?

When my lemon bars are too soft, I first check whether the filling was cooked long enough.

Cornstarch needs sufficient heat to activate its thickening properties, so I make sure the mixture reaches a bubbling, thick, pudding-like consistency before removing it from the stove.

I also allow enough refrigeration time. If the filling remains soft after 1 hour, I leave the bars in the refrigerator longer, preferably overnight.

Can I use bottled lemon juice instead of fresh lemon juice?

I can use bottled lemon juice if necessary, but I strongly prefer freshly squeezed lemon juice.

Fresh lemons provide a brighter flavor and more natural citrus aroma, which I find especially important in a dessert where lemon is the main ingredient.

I also use fresh lemon zest to enhance the overall flavor.

What type of plant-based milk works best for this recipe?

I find unsweetened soy milk and oat milk particularly reliable because they provide a smooth texture and relatively neutral flavor.

Unsweetened almond milk also works well, while coconut milk adds a subtle richness and coconut flavor.

I avoid sweetened or strongly flavored plant-based milk because the filling already contains enough sugar, and I want the lemon and lavender flavors to remain the focus.

Can I prepare these Lavender Lemon Bars ahead of time?

Absolutely. I actually prefer making these bars a day ahead because the extra chilling time allows the filling to set completely.

I prepare the crust and filling, assemble the bars, and refrigerate them overnight.

Before serving, I lift them from the pan, slice them into neat squares, and finish with powdered sugar and a small amount of culinary lavender.

This makes them one of my favorite make-ahead desserts for parties and family gatherings.

Conclusion

These Lavender Lemon Bars are a beautiful combination of bright citrus flavor, delicate floral notes, and creamy vegan goodness. I love how the buttery shortbread crust provides the perfect foundation for the smooth lemon-lavender filling, creating a dessert that feels both refreshing and indulgent.
