BEST EVER American Buttercream Frosting
This American buttercream frosting is light, fluffy, silky smooth, and surprisingly not too sweet. Unlike traditional American buttercream that can sometimes taste gritty or heavy, this newer whipped method creates a glossy bakery-style frosting with an incredibly smooth texture.
The secret is whipping the butter until very light and airy, then adding hot heavy cream before the powdered sugar. The warmth helps soften the sugar while the long whipping time creates a mousse-like buttercream that pipes beautifully and spreads like a dream.
I used to make large batches of buttercream every week when I ran my cake business from home. Back then, I relied on meringue powder and decorator-style methods because most of my cakes needed to survive transport, heat, and hours of decorating. Over time, though, I simplified the recipe for everyday baking — and honestly, I prefer this version now. It’s easier, silkier, and tastes more like real buttercream instead of pure sugar.
Why You’ll Love This Recipe
- Silky smooth texture with no gritty mouthfeel
- Light and fluffy despite being an American buttercream
- Easy to make with simple ingredients
- Perfect for cakes, cupcakes, layer cakes, and piping swirls
- Stable enough for decorating while still soft and creamy
- Pipes beautifully and crusts lightly
- Much less sweet tasting than traditional American buttercream
Why This Buttercream Is So Smooth
Most American buttercream recipes are made by simply beating butter with powdered sugar. While easy, that method can leave the frosting dense, overly sweet, or slightly gritty.
This whipped buttercream method works differently:
- the butter is whipped first until extremely light,
- hot cream helps soften the powdered sugar,
- and the frosting is whipped for much longer than traditional recipes.
The result is a silky smooth buttercream with a glossy finish and a texture closer to bakery frosting or Swiss meringue buttercream — but without cooking egg whites.
Ingredients and substitutes
- Unsalted butter – Use softened butter but not greasy or melted. Good-quality butter gives the best flavor.
- Powdered sugar – Sift if lumpy. Use less for a softer frosting or more for a firmer piping consistency.
- Heavy cream – Hot heavy cream is the secret to the silky texture. Whole milk works too, but cream gives a richer result.
- Vanilla extract – Use clear vanilla if you want bright white buttercream.
- Almond extract – Just a tiny dash adds bakery-style flavor without overpowering the vanilla.
- Salt – Essential for balancing the sweetness.
Step-by-step: How to make the best American Buttercream
Cream the butter
In the bowl of a stand mixer fitted with the paddle attachment, whip the softened butter on medium-high speed for about 10 minutes until very pale, light, and fluffy.
Pro tip — Don’t rush this step. The butter should almost look whipped before adding anything else.
Add the hot cream
Warm the heavy cream until hot but not boiling. Slowly pour it into the butter while mixing on medium speed.
Add the vanilla extract, almond extract, and salt.
Continue whipping for another 5 minutes until smooth and creamy.
Pro tip — The buttercream may look slightly loose at first. Keep mixing and it will become silky smooth.
Add the powdered sugar
Add the powdered sugar in two batches on low speed.
Once incorporated, increase the mixer speed to medium-high and whip for another 8 to 10 minutes until very light and fluffy.
Pro tip — Long whipping creates the smooth glossy texture and removes the heavy sugary feel common in traditional buttercream.
Consistency Guide
This buttercream is very versatile and can easily be adjusted depending on how you plan to use it.
- For frosting cakes – Use the recipe exactly as written for smooth frosting and filling layer cakes.
- For cupcakes – Perfect for piping swirls and rosettes.
- For stiffer piping – Add an extra ½ to 1 cup powdered sugar.
- For softer buttercream – Add 1 to 2 tablespoons warm cream and whip again.
- For hot climates – Replace part of the butter with vegetable shortening if needed.
Can I make chocolate buttercream?
Yes. Add cooled melted chocolate or cocoa powder after the buttercream is fully whipped.

Frequently asked questions
A buttercream frosted cake can be left at room temperature for up to 3 days unless it has a perishable filling.
