You can pipe lavender buttercream frosting onto lemon cupcakes or spread it over a simple vanilla cake.
 
It also works beautifully with shortbread cookies and macarons.
 
The floral flavor lifts everything it touches.
 

3. It’s Easier Than It Looks

The only extra step is infusing the lavender.
 
Once you know that trick, lavender buttercream frosting becomes a go-to recipe.
 

How to Make Lavender Buttercream Frosting Step by Step

Now let’s get into how to make lavender buttercream frosting from scratch.
 
This recipe makes enough to frost about 12 cupcakes or one 8-inch layer cake.
 

1. Gather Your Ingredients

To make lavender buttercream frosting, you’ll need one cup of unsalted butter at room temperature, three to four cups of powdered sugar, two to three tablespoons of heavy cream, one teaspoon of vanilla extract, a pinch of salt, and one to two teaspoons of dried culinary lavender.
 
Make sure your lavender is food-grade.
 
The lavender in craft stores is not safe to eat.
 

2. Infuse the Cream With Lavender

The best way to make lavender buttercream frosting is to infuse the cream first.
 
Warm the heavy cream gently in a small saucepan.
 
Add the dried lavender, then remove the pan from the heat and let it steep for about 15 minutes.
 
Strain out the buds and let the cream cool completely.
 
This gives you a smooth lavender buttercream frosting with no gritty bits.
 

3. Beat the Butter Until Fluffy

In a stand mixer, beat the butter on medium speed for about five minutes.
 
It should look pale and fluffy.
 
This step is what gives lavender buttercream frosting its light, silky texture.
 
Don’t rush it.
 

4. Add the Powdered Sugar Gradually

Add the powdered sugar one cup at a time, mixing on low speed.
 
Once it’s all in, turn the mixer up and beat for another two minutes.
 
Your lavender buttercream frosting should look thick and glossy at this point.
 

5. Finish With the Infused Cream and Vanilla

Pour in the cooled lavender cream, vanilla, and salt.
 
Beat for another two to three minutes until the lavender buttercream frosting is smooth and spreadable.
 
If it’s too thick, add a splash more cream.
 
If it’s too thin, add a little more powdered sugar.
 

Tips to Keep Lavender Buttercream Frosting From Tasting Soapy

The biggest mistake people make with lavender buttercream frosting is using too much lavender.
 
Here are some tips to keep it balanced:
 

1. Start Small and Taste as You Go

Begin with just one teaspoon of lavender when you make lavender buttercream frosting.
 
Taste it, then add more if you want a stronger flavor.
 
You can always add, but you can’t take away.
 

2. Use Culinary Lavender Only

Not all lavender is meant for eating.
 
English lavender and Provence lavender are the best choices for making lavender buttercream frosting.
 
They have a sweeter, milder flavor than other varieties.
 

3. Strain the Buds Before Mixing

Whole lavender buds in lavender buttercream frosting can taste bitter and feel gritty.
 
Infusing the cream and straining it out gives you all the flavor with none of the texture issues.
 

4. Balance With a Pinch of Salt

A small pinch of salt in lavender buttercream frosting sharpens the flavor and keeps it from tasting flat.
 
It won’t make your frosting salty, it just makes the lavender sing.
 

So, How Do You Make Lavender Buttercream Frosting?

You make lavender buttercream frosting by infusing heavy cream with culinary lavender, then whipping that cream into butter, powdered sugar, and vanilla.
 
The result is a smooth, floral frosting that tastes elegant without being overpowering.
 
The key steps are simple: steep the lavender, strain it well, and start with a small amount so the flavor stays balanced.
 
Once you learn how to make lavender buttercream frosting, you’ll find yourself reaching for it whenever you want a dessert that feels a little special.
 
So grab some culinary lavender, soften your butter, and give lavender buttercream frosting a try this weekend.
