Nothing says spring quite like lavender buttercream frosting. This lightly floral frosting is made with dried culinary lavender for a delicate herbal flavor and tinted naturally with fresh blueberry juice for a soft, dreamy pinkish-purple hue. Perfect for frosting cupcakes, layering between cakes, or spreading on cookies, it’s a beautiful way to bring a little garden-inspired charm to your desserts.
Flavoring with Lavender
Lavender is a strong herb that should be used sparingly to prevent overtaking a recipe. Its far more enjoyable as a background taste than eating an overly floral infused dessert. This is why I only use a small amount mixed with vanilla extract.
The flavor potency of lavender increases as it dries. Which means a recipe should use ⅓ dried flowers in comparison to fresh. In this recipe I have used 2 teaspoons of dried lavender for a large amount of buttercream to cover my cake. If I were to substitute with fresh lavender flowers I would use 6 teaspoons.
What is the difference between English and French Lavender?
English Lavender (L. Angustifolia) is the sweetest of all lavender species, and is most commonly used for baking. Some varieties even give off a hint of lemon.
French lavender has a scent of camphor and menthol, which is more medicinal flavor. It is also known to be toxic in very large quantities. So, its best to just enjoy the beautiful flowers as they bloom in your garden or use for decorations.
What is Culinary Lavender?
Culinary lavender is often known as dried flower petals/buds taken off a stem just after opening (stems as well). However, the flowers and leaves can also be used fresh. Lavandula Angustifolia is the most common species of lavender for baking.
If you're new to experimenting with lavender start with just a teaspoon of the Organic Lavender and sugar mixture. Continue to add the rest into your frosting to see how your taste buds feel about floral enhancement.
🌿 Ingredients You Need & Why
- Unsalted Butter
- I highly recommend using cultured butter, European style with 82% butterfat is a higher quality butter and for best flavor.
- Higher butterfat contributes to a smoother, creamier texture in the buttercream resulting in a frosting that's both luscious and easy to pipe!
- Confectioners Sugar (aka powdered sugar)
- Confectioners sugar dissolves seamlessly into the softened butter, for a smooth, airy texture.
- Culinary Lavender
- Use dried culinary-grade lavender buds—organic if possible. Try this culinary lavender available on Amazon. You can also find culinary lavender in some health food or organic grocery stores.
- Vanilla Bean Paste or Pure Vanilla Extract
- Adds depth, aroma, and lovely vanilla flavor.
- Heavy Cream
- A splash of heavy cream lightens the buttercream's texture, making it more spreadable and easier to work with.
- Natural Blueberry & Blackberry Juice Food Coloring
- Fresh blueberry and blackberry juices provide a natural, subtle hue to the buttercream, ranging from soft lavender to deeper purple tones, depending on the ratio used.
- This method avoids artificial dyes, adding both color and a hint of fruitiness.
- Sea Salt
- A pinch helps balance the sweetness of the added confectioners sugar. Taste and adjust to your liking.
How to Naturally Color Lavender Buttercream Frosting
The purple tint from the combination of blueberry and blackberry juice creates a lovely natural shade of light lavender for this buttercream frosting.
- Add ⅛ cup blueberries and 2 tablespoon water into a small sauce pan. Heat on medium for 5-6 minutes, stirring and gently mashing the berries. Once the juices are pouring out into the saucepan remove from heat and set aside.
- Strain the berries through a metal sieve into a small bowl. Discard the berry solids. Or save for a smoothie!
- Repeat with ⅛ cup blackberries using a clean saucepan and separate final bowl.
- Add small amount of the blueish blueberry juice and the pinkish red blackberry juice to your finished buttercream.
- Adding more blue will create a deeper purple. So, just play around until you find the shade you like!
- You will have a blueberry lavender buttercream cake frosting that can also be used to fill macarons or cookie sandwiches!!
- Another way to get a deeper purple Lavender Buttercream is to use juice from a purple potato! Slice and boil two purple potatoes, using the juice to dye the frosting.

Would the flavor of lavender be to strong if I used it for the layers as well as the outside?
Alexis Kamryn
What piping tip did you use in the pictures of the cake?
Jenn
Hi Alexis! This was a Wilton 6B
Zar Imr
Hi, how much frosting would this make? Could I frost and fill a three layer 8 inch cake with one batch?
Jenn
This recipe makes enough for three 6 inch layers or two 8 inch layers. I would make a double batch for an 8 inch three layer, depending on how thick you like your frosting.
Layne Tisdel Martin
Is this really supposed to have salt in it? There's 1 tsp in the ingredients list but the instructions never say when/if to add it.
Jenn
Yes, you add salt in step 2. This helps balance the super sweetness from all the powdered sugar. If you prefer not to add it, that is ok too 🙂
Lisa
How many macarons would one batch fill?
