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.

|---|---|---|
| Buttercream feels gritty | Sugar not whipped enough | Continue whipping several more minutes |
| Frosting too soft | Butter too warm | Chill 10–15 minutes then whip again |

Frequently asked questions
A buttercream frosted cake can be left at room temperature for up to 3 days unless it has a perishable filling.
And, beyond that, you can keep it in the fridge. In fact, I like to place it in the fridge for an hour until the buttercream firms up slightly, then wrap plastic around it to protect it from other food odors.
Yes. Store in the fridge for up to one week. Bring to room temperature and rewhip before using.
No. This recipe uses less powdered sugar than traditional American buttercream, which gives it a lighter texture and less sugary taste.
Yes, absolutely. And, the trick to covering a buttercream cake with fondant is to make sure you chill the cake really well, for more than a few hours. In fact, I like to keep my cakes overnight, so when it’s ready for fondant the cake is chilled completely, and I have a nice firm surface to work with.
Yes. Freeze for up to 3 months in an airtight container.
Yes, lightly. Enough for smoother decorating but still soft and creamy when eaten.
Absolutely. Gel food coloring works best.
This is a general guide I use. Also note, I have given you the filling and frosting separately so you can choose another filling with your buttercream. If you choose to fill and frost the cake with buttercream, you can use the last column/total.

I absolutely love this buttercream… However, how do I prevent my KitchenAid from walking up when adding the remainder of the powdered sugar before I add the butter? It’s like cement.
You just have to stir it up and increase speed if neccessary.
hello! excitedly gave this a whirl! it’s a good buttercream but still has a bit of that grit sugar texture even though extremely mild but there. I did only do a 1/4 batch but everything came along as it should. any ideas why it isn’t perfectly smooth? thanks I’m advance!
Please check to make sure you are not using cane sugar as it can be a bit grainy. The hot cream melts some of the butter and sugar, which takes away the grittiness.Thanks
Question: I LOVE this icing as is but can I use cream cheese for part of the butter? Thank you for posting.
This recipe worked perfectly for me, and as others said, it is delicious! I wish I could upload a photo of the pretty birthday cupcakes I made with it. I’m so proud of them, thank you Veena!
Thank you, Alix. You can share a picture in our facebook group We would love to see it.
I just made this icing to test it out for a cake for my hubbys birthday and i could barely restrain myself from eating it all from the bowl. It’s so delicious! I used French vanilla creamer and I did have to add some when incorporating the sugar because it was so thick my mixer sounded like it was struggling ? I also used butter emulsion instead of almond extract. I have it in my freezer as I won’t need it until March 16th, it should still taste fine? I know to thaw it and re whip it 🙂 I do need it a bit thicker so I can pipe some shell borders and rosettes. Thank you thank you thank you!
Thank you for the lovely feedback and you are very welcome Hannah. I am happy you enjoyed this buttercream. Yes, it does freeze beautifully too.
Hello Veena I can’t wait to try this recipe. Can I use dried egg white powder to make sure it crust?
Yes, you can Hayley.
Is it possible to replace all the butter in this recipe with shortening? I want to practice my frosting techniques on a cake dummy, and since butter is so expensive now, I don’t want to spend money on it for practicing on a fake cake. Thanks.
Vegetable shortening needs more powdered sugar to stabilize it. So you may need more powdered sugar but check the consistency as you always do.
Amazing!
