What Does Lavender Buttercream Taste Like?

Lavender has a gentle floral aroma with hints of mint and rosemary undertones. When infused correctly, it creates a sophisticated flavor similar to European pastries. The sweetness of powdered sugar balances the herbaceous notes, resulting in a frosting that tastes refined rather than overly sweet.

If you’ve never tried lavender desserts before, think of it as a subtle botanical twist on vanilla frosting — familiar yet exciting.

Ingredients

1 cup vegan butter, softened (stick-style works best)
3–4 cups powdered sugar (depending on desired sweetness)
1 tablespoon culinary lavender buds
2–3 tablespoons plant-based milk (almond, oat, or soy)
1 teaspoon vanilla extract
Pinch of salt
Optional: natural purple or violet food coloring

Instructions

Infuse the Lavender
Heat the plant-based milk gently until warm but not boiling. Add the lavender buds and let them steep for 10–15 minutes. Strain out the lavender and allow the milk to cool completely.
Beat the Vegan Butter
In a large mixing bowl, beat the softened vegan butter with a hand mixer or stand mixer for 2–3 minutes until light and fluffy. This step creates the smooth base for your frosting.
Add Powdered Sugar Gradually
Add powdered sugar one cup at a time, mixing on low speed first, then increasing speed once incorporated. Scrape down the sides as needed.
Incorporate Flavorings
Add the cooled lavender-infused milk, vanilla extract, and pinch of salt. Beat on medium-high speed for another 2–3 minutes until fluffy and smooth.
Adjust Consistency
If the frosting is too thick, add a small amount of plant milk. If too thin, add more powdered sugar until the desired consistency is reached.
Optional Coloring
Add a tiny amount of purple food coloring if you want a pastel lavender shade. Mix thoroughly.
Use or Store
Use immediately for frosting cakes or cupcakes, or store in an airtight container until needed.

Tips for Perfect Vegan Buttercream

Use High-Quality Vegan Butter

Stick-style vegan butter creates a firmer, more stable frosting than spreadable tubs.

Don’t Skip the Salt

A pinch of salt balances sweetness and enhances the floral notes.

Infusion Matters

Over-steeping lavender can create a soapy taste. Stick to 10–15 minutes for best flavor.

Beat Long Enough

Fluffy buttercream requires sufficient whipping time. Air incorporation creates lightness.

Variations and Flavor Ideas

This recipe is incredibly adaptable. Try these variations:

Lemon Lavender Buttercream

Add 1–2 teaspoons lemon zest for a fresh citrus twist.

Honey-Style Lavender (Vegan)

Use a small amount of agave or maple syrup to mimic floral honey notes.

Increase vanilla extract slightly for a sweeter profile.

Lavender Rose Buttercream

Add a drop of rose water for a romantic flavor combination.

Is Lavender Safe to Eat?

Yes — but only culinary-grade lavender should be used. Decorative or garden lavender may contain pesticides or be too bitter. Culinary lavender is specifically grown for food use and has a sweeter aroma.
