My husband’s favorite desserts are, hands down, citrus desserts, and more often than not, he asks me to make gluten free lemon bars for his birthday dessert. 

I first learned about the lemon-lavender combination from some friends who grew lavender on their farm and so put lavender in everything they could. If it wasn’t for them, I would never have tried making these, but it lends an air of sophistication to a simple dessert. 

How do you add lavender to lemon bars? 

In this recipe, we use real lavender buds to make lavender sugar, which we’ll sift out before adding the sugar to the lemon bars. 

There are many lavender infused recipes that use techniques such as making and adding lavender tea, using artificial lavender flavoring, lavender extract, or lavender essential oil. 

For this, we want a noticeable, natural, but not over-powering scent. 

Making lavender sugar is simple and effective.

Where do I get lavender? 

Depending on your area, you may or may not be able to find lavender locally or even grow it yourself. 

I have found lavender at Hobby Lobby in the past, as well Whole Foods. 

However, I actually ordered dried culinary lavender from Amazon for this recipe and was very happy with how well-preserved it was. 

Are these lemon bars gluten free? 

You know that almost every recipe on Frugal Farm Wife is gluten free, with the exception of sourdough recipes. This is mostly because my husband has celiac disease, so we do our best to blend backwoods homestead living with modern food allergy cooking. 😉 

That said, Yep! These are super easy to make gluten free. 

However, the recipe is nearly the same as using wheat-based crust, so feel free to swap gluten-free flour for all purpose flour. 

Pro tip for making gluten-free lavender lemon bars: Skip greasing the pan, or lining it with parchment paper. Making it too easy for your crust to lose its grip on the pan can cause it to float to the top, leaving you with upside-down lemon bars. Still tasty, but not as easy to serve. 

Can I make these lemon bars without lavender? 

Of course! But you’re definitely missing out if you do. Just skip the lavender sugar infusion. You can also use the more traditional recipe I linked to above or try our paleo lemon bars. 

Ingredients for Lavender Lemon Bars

As elegant as these lemon bars are, the ingredients are actually very simple, and the only real difference from traditional lemon bars is the addition of lavender buds. 

for the shortbread crust: 

  • Flour. Of course, you can use all-purpose white flour, but for us gluten-free folks, it’s a little more involved. I use a mixture of super fine rice flour and cornstarch or arrowroot powder. I find that using super fine flour helps keep the crust intact throughout the baking process.
  • Powered sugar. Using this, as opposed to granulated sugar, helps distribute the sugar evenly and keeps the crust super smooth
  • Butter. Of course, it wouldn’t be short bread crust without butter. You can use salted or unsalted butter here. 

For the filling, we have just a few more ingredients. 

  • Eggs. These are what create the custard effect, essentially the gel that makes the lemon bar we all know and love. 
  • Granulated sugar. Sugar not only counters the tartness of the lemon, but it acts as a liquid in baking and impacts the texture of your bar. Not only that, but in this recipe, it serves as a vehicle for the lavender flavor.
  • Lavender buds. Packed with oils that carry the flavor, dried lavender buds are incredibly potent. In this lavender lemon bar recipe, we use them by blending them with the sugar and then sifting out the bigger pieces.
  • Lemon Juice. It wouldn’t be a lemon bar without lemon! This acts as your main flavor and the liquid in our recipe
  • Cornstarch aids in thickening the filling. While the eggs are responsible for the main custard, the cornstarch helps keep it stable. 
  • Lemon Zest. While optional, lemon zest adds a deeper dimension to the lemon flavor profile and in my opinion, is worth buying a lemon for.  

How to Make Lavender Lemon Bars

As mentioned above, we use lavender buds to make lavender sugar to flavor these bars. 

  1. So the first step is to blend your lavender and sugar together. Simple pulse it in a food processor or blender, and set aside to infuse

  1. I tried making this cake and changed the recipe a bit in terms of lemon ratio to reduce the sweetness because I am at risk of diabetes and luckily the taste really surprised me.
