Classic Vanilla Buttercream Frosting — Full Recipe

The frosting in your photo appears to be a thick, fluffy American-style vanilla buttercream—the type that holds its shape beautifully for piping and cake decorating. The basic formula is softened butter, powdered sugar, vanilla, and a small amount of milk or cream.

Recipe at a glance
Yield: about 3–3½ cups
Prep time: 10–15 minutes
Cooking: none
Difficulty: Easy
Best for: cakes, cupcakes, cookies, piping and cake borders
Ingredients
Main recipe
1 cup (226 g) unsalted butter, softened
4½–5 cups (about 540–600 g) powdered/confectioners’ sugar, sifted
2 teaspoons pure vanilla extract
2–4 tablespoons whole milk or heavy cream
⅛ teaspoon fine salt

This ratio is consistent with classic American buttercream formulas, although recipes vary in the amount of powdered sugar and liquid depending on the desired stiffness.

For the very stiff, pipeable look in your photo

Use:

1 cup butter
5 cups powdered sugar
2 tbsp heavy cream
2 tsp vanilla
⅛ tsp salt

Start with only 2 tablespoons of cream. Add more only if necessary.

Step-by-step instructions
1. Bring the butter to the correct temperature

Take the butter out of the refrigerator about 30–60 minutes before making the frosting.

You want it:

soft enough to press with your finger
cool to the touch
not shiny
not melted
not oily

Do not microwave it until melted.

Softened butter is important because it whips into a lighter, smoother frosting.

2. Sift the powdered sugar

Sift the powdered sugar through a fine-mesh sieve.

This removes lumps and gives you a smoother buttercream, particularly important if you want to pipe the pronounced swirls seen in the photograph.

3. Whip the butter

Put the softened butter into a large mixing bowl.

Using a hand mixer or stand mixer, beat on medium speed for approximately 2–3 minutes.

The butter should become:

pale
creamy
smooth
noticeably lighter

Scrape down the sides of the bowl once or twice.

Some recipes specifically recommend about three minutes of beating at this stage to make the butter light and fluffy.

4. Add powdered sugar gradually

Turn the mixer to low.

Add the powdered sugar approximately ½–1 cup at a time.

Mix slowly after each addition.

Don’t immediately turn the mixer to high, or you’ll create a cloud of powdered sugar.

Continue until all the sugar is incorporated.

At this point, the mixture may look very thick and somewhat dry. That’s normal.

5. Add vanilla and salt

Add:

2 teaspoons vanilla
⅛ teaspoon salt

Mix on low until incorporated.

The salt helps balance the sweetness.

6. Add the cream

Add 2 tablespoons heavy cream.

Mix on low until incorporated.

Then increase to medium-high speed and beat for approximately 2–3 minutes.

The frosting should become fluffy, smooth and creamy.

If it is too stiff, add additional cream ½–1 teaspoon at a time.

If it is too soft, add powdered sugar 1 tablespoon at a time.

This gradual adjustment is important because even small differences in butter temperature and powdered sugar can change the final consistency.

How to get the exact fluffy texture in your photo

The picture shows a very thick decorating buttercream, rather than a loose frosting.

For that texture:

Use

1 cup butter + 5 cups powdered sugar + only 2 tbsp cream

Then whip thoroughly.

You should be able to lift the beaters and see a firm peak that doesn’t immediately collapse.

If the frosting droops:

Add 2–3 tablespoons powdered sugar.

If it is too hard to spread:

Add cream ½ teaspoon at a time.

The secret to ultra-fluffy buttercream

After the ingredients are incorporated, don’t stop immediately.

Beat the buttercream for another 2–3 minutes at medium-high speed.

Stop and scrape the bowl.

Then beat another 30–60 seconds.

This incorporates air and produces the light, fluffy appearance shown in the image.

How to make the swirls shown in the picture

Use a piping bag fitted with a large star tip.

A large open-star or closed-star tip works particularly well.

For a rosette
Hold the piping bag vertically.
Start in the center.
Squeeze steadily.
Move the tip around the center in a circular motion.
Continue outward.
Stop squeezing.
Lift the tip away.

For a large cake, you can pipe individual rosettes close together until the entire surface is covered.

Coloring the buttercream

For colored frosting, use gel food coloring rather than a large quantity of liquid food coloring.

Add a small amount after the buttercream is completely mixed.

Mix thoroughly.

For pastel colors, start with an extremely small amount.

For deep colors, let the buttercream sit for 30–60 minutes after coloring; the color can intensify as it rests.

Gel/paste coloring is also recommended by established baking recipes because it provides strong color without adding much extra liquid.

Chocolate version

Add:

½–¾ cup unsweetened cocoa powder

You may need an additional 1–2 tablespoons cream.

For a richer chocolate frosting, replace some of the powdered sugar with cocoa rather than simply adding a huge amount of cocoa.

Strawberry buttercream

Add:

½ cup thick strawberry jam or preserves
½–1 tsp vanilla

Reduce the milk/cream initially because the jam adds moisture.

For a stronger natural strawberry flavor, use freeze-dried strawberry powder.

Lemon buttercream

Use:

1½ tsp vanilla
1 tbsp fresh lemon juice
1–2 tsp finely grated lemon zest

Reduce the milk slightly.

Coffee buttercream

Mix:

1–2 tsp instant espresso powder
1 tbsp warm cream or milk

Allow it to cool, then mix it into the buttercream.

Salted caramel buttercream

Add:

¼ cup thick caramel sauce
¼ tsp sea salt

Because caramel adds liquid, you may need a little additional powdered sugar.

Peanut butter buttercream

Add:

½ cup creamy peanut butter

Reduce the butter slightly or add extra powdered sugar as needed.

Allergen: contains peanuts.

Dairy-free version

Use:

dairy-free baking butter
powdered sugar
vanilla
plant-based milk

Good choices include unsweetened oat, soy or almond milk.

Allergen warning: almond milk contains tree nuts.

Coconut version

Replace some of the milk/cream with coconut cream and add:

½ tsp coconut extract

For extra coconut flavor, add finely shredded unsweetened coconut.

Frequently Asked Questions
Why is my buttercream grainy?

Usually because the powdered sugar wasn’t sufficiently incorporated or contains lumps.

Fix: continue beating and make sure the powdered sugar was sifted.

Why is my frosting too sweet?

American buttercream is naturally quite sweet because powdered sugar is its primary structure-forming ingredient.

Try:

adding a small pinch more salt
using less powdered sugar if you don’t need very stiff piping
adding cream cheese for a tangier frosting
adding unsweetened cocoa for chocolate buttercream

Don’t dramatically reduce the powdered sugar if you need the frosting to hold a detailed piping shape.

Why is my buttercream runny?

Possible causes include:

butter was too warm
too much milk/cream
warm kitchen
insufficient powdered sugar

Fix: refrigerate for 10–20 minutes, then whip again. If still too soft, add powdered sugar gradually.

Why is my buttercream hard?

It probably contains too much powdered sugar or is cold.

Add ½ teaspoon cream at a time and mix until smooth.

Can I use salted butter?

Yes.

If using salted butter, omit the added salt initially. Taste after mixing and add a tiny amount only if necessary.

Can I use milk instead of heavy cream?

Absolutely.

Whole milk gives a lighter frosting, while heavy cream generally produces a richer texture.

Classic recipes commonly use either milk or cream.

Can I use margarine?

Yes, but the flavor and texture will change.

Real butter generally provides the best traditional buttercream flavor.

Can I make this without a mixer?

Yes, but it requires considerably more effort.

Use a sturdy spatula or wooden spoon and softened butter. An electric mixer makes it much easier to achieve the fluffy texture seen in your photo.

How long can I keep buttercream?

For best quality, keep it covered.

A properly stored buttercream can be refrigerated for several days; one published classic recipe recommends up to about a week refrigerated, while other recipes use shorter windows.

Before using refrigerated buttercream:

Bring it toward room temperature.
Beat it again.
Adjust the consistency with a tiny amount of cream if needed.
Can I freeze buttercream?

Yes.

Place it in an airtight freezer-safe container.

Thaw it gradually in the refrigerator, then bring it toward room temperature and re-whip before decorating.

Can I leave a buttercream cake outside?

Be careful in warm weather. Butter-based frosting softens considerably with heat.

For outdoor summer events, keep the cake chilled as long as practical and don’t leave it sitting in direct sun.

Can I make it less sweet?

Yes, but there is a trade-off.

The powdered sugar isn’t only for sweetness—it also provides the structure that makes American buttercream thick and pipeable.

For substantially less sweetness, consider a different frosting style such as Swiss meringue buttercream or a cream-cheese-based frosting.

Best formula for the photo

If your goal is to reproduce that exact thick, smooth, pipeable appearance, I’d use:

226 g unsalted butter
600 g powdered sugar
2 tsp vanilla
30 g heavy cream
⅛ tsp salt

Method

Whip butter → add sugar gradually → add vanilla/salt → add cream → whip 3 minutes → scrape bowl → whip another minute → pipe immediately.
