Fluffy Vanilla Buttercream Frosting (American Buttercream)
My fluffy vanilla buttercream frosting is velvety smooth, creamy and fluffy with a stable texture that pipes beautifully on your favorite cupcakes and works well with layer cakes. It’s made using just 5 simple ingredients which comes together to create a rich classic buttercream that isn’t overly sweet.

Hey team, Nick here! If there’s one thing you need to know about this frosting is that even though it’s a classic frosting recipe, it’s not as sweet as other frostings you’ll find floating around. It’s creamy and fluffy. Now, you’d think we’re compromising on stability here because there’s less sugar, but it holds its shape beautifully and works so well!


I love spreading it on my soft vanilla layer cake and swirling it on my new fluffy vanilla cupcakes which stay moist for days by the way. I double dose the vanilla in the frosting and the cupcakes by adding both pure vanilla extract and vanilla bean paste. You know… for the vanilla bean specs!
Oh by the way, this frosting is a great all rounder. You can easily color it with food gel and flavor it with freeze dried fruits or extracts. I actually used this frosting to create my bright strawberry frosting recipe using real strawberries. The flavor is insane.
A Frosting Crash Course
- Prepping ingredients ahead of time – Starting with softened butter is non-negotiable. Read my guide to softening your butter, it’ll give you fluffy frosting.
- Sifting your powdered sugar will prevent lumps and help everything blend smoothly for flawless frosting!
- Getting your frosting fluffy – Whip your butter on its own until it’s pale, creamy, and full of air before adding the sugar, about 10 minutes. You’ll end up with a fluffy frosting instead of a dense and greasy one.
- Flavoring and coloring your frosting – Enhance the flavor with vanilla extract, zests, or flavors, and add gel food coloring for vibrant, streak-free results. A little goes a long way, so start small and build up.
How To Make Your Vanilla Buttercream


- Start by creaming your softened butter, vanilla extract and salt in a large mixing bowl using a stand mixer fitted with a paddle attachment. Mix on medium-high speed for about 10 minutes, until the butter is pale, fluffy, and creamy in texture. You can also use an electric hand mixer.
Tip – Don’t skip scraping down the bowl as you mix. It ensures every bit of butter and sugar is evenly combined. Do it before and after you add the sugar.


- Sift the powdered sugar into the creamed butter using a fine sieve. Literlay can not stress how important it is that you do this. You’ll avoid lumps!
- Start mixing on low speed until the sugar is fully incorporated and no dry powder remains. Then, whip on medium-high speed for 10 minutes until the frosting becomes light and smooth, pale, and stiff enough to hold its shape, similar to stiff peaks in whipped cream.


The result- A smooth, fluffy, and creamy frosting, with a pale color and just enough stiffness to hold its shape when piped. If you give it a cheeky taste, you’ll feel the creaminess and vanilla first before you taste the sweetness.
To smooth out your frosting, add 1-2 tablespoons of cold heavy cream. Whip it into the frosting on medium-high speed. The cream helps create a smoother texture, and its cold temperature slightly stiffens the frosting, making it easier to work with. I’d skip it if it’s a warm day.
Frosting not smooth enough?
These are the two techniques I use to smoothen my frosting and make it creamy and smooth again.
- Microwave half the frosting for 10 seconds until it’s soft and jiggly (not melted), then mix it back into the rest on medium high speed until creamy and smooth.
- To get rid of air bubbles, beat the frosting on low for 5 minutes or use a spatula to fold and smooth it out right before piping or spreading.
If it’s a warm day, just be a little cautious with these techniques because it can cause your frosting to become overly soft and lose structure. On a warmer day, just re-whip, or of the frosting is too soft, pop it back in the fridge for 30 minutes before re-whipping.
Vanilla Buttercream VS Other Buttercreams
This is an all-round buttercream which can be used for many different things. But here’s how it compares to other frostings.
- Ermine Frosting (my favourite frosting!) – Lighter and creamier, made with a cooked milk and flour base, and less buttery in flavor. Rich in flavor like pastry cream.
- Swiss Meringue Buttercream – Silky and less sweet, whipped from egg whites and sugar, but requires more precision to make.
- German Buttercream – Rich and custard-like, made with pastry cream, offering a deeper flavor and softer texture.
- French Buttercream – Ultra-rich and decadent, made with egg yolks and sugar, perfect for indulgent desserts but softer and less stable.
Why would you make this frosting instead? It’s way easier and quicker to make. It uses simple ingredients, and it works for pretty much everything!

Fluffy Vanilla Buttercream Frosting (American Buttercream Frosting)
Serves 1 batch
Ingredients
Vanilla Buttercream Frosting
- 500 g unsalted butter, softened (see notes)
- 1 tsp salt
- 1-2 tsp vanilla extract
- 15 g vanilla bean paste, (optional)
- 20 g heavy cream, cold (see notes)
- 400 g powdered sugar
Instructions
Vanilla Buttercream Frosting
- Cream butter – Add your softened butter, salt, vanilla extract and vanilla bean paste (optional) to a large bowl. If using a stand mixer fit it with the paddle attachment. Beat on medium high speed for 5 minutes until pale and fluffy. You will want to scrape down the bowl halfway through with a spatula to ensure everything beats together evenly!
- Add sugar – Scrape the bowl down using a spatula and add all of the sifted powdered sugar. Begin beating on low speed at first. When no dry ingredients are showing, turn the speed up to medium high speed again and beat for 5 minutes.
- Add cream – finish by adding the heavy cream to smoothen out your frosting. Beat in on medium high speed for 2 minutes.
How to make your frosting smooth!
- American buttercream frosting has a slight grit and is stiffer than most frostings. It’s great for layering cakes or frosting cupcakes or even making frosting decorations on your cakes. Here are some ways to smoothen out your frosting!
- Microwave half the frosting – If it’s a cold day or your frosting stiffened up, you can smoothen it out by adding half of the frosting into a heatproof bowl and popping it into the microwave for 10 seconds or until jiggly in the center, not melted. Add to the rest of the frosting and beat on medium speed for a couple minutes to combine. This will help freshen it up!
- Beat air out – Right before using or adding to a piping bag, use a spatula to beat the air out of the frosting until smooth. This works great if your frosting has just been made. Alternatively, you can beat the frosting on the lowest speed on your mixer for about 5-10 minutes. This will make your frosting ultra-smooth but also softens it. Don’t do this on warm days as it can over soften the frosting or even cause it to split. Just use the spatula to beat out the air.

I just tried your recipe and it came out great! So easy to make too! Thank you!
That’s awesome! N x
Thanks! N x
I have been trying to find a buttercream frosting recipe that wasn’t too sweet. I found this one and I was really hopeful about it. I followed the instructions and recipe exactly as shown. I was disappointed with the results. It was awful. It was way too sweet. I even tried to make it a second time but the results were the same. I had to throw both batches away because it was way too sweet
Oh my goodness! It’s frosting Lesa! It’s supposed to be sweet! Lol.
Hi Nick! I was wondering if the same trick of milk powder used in the cream cheese frosting can be used here in order to make the buttercream less sweet? Basically can I just in every recipe just swap part of the icing sugar for same quantity of milk powder, in order to keep the same stability, consistency, and ability to crust on top (and be able to pack the product) but without the additional sweetness? Or they don’t work exactly like that and too muck milk powder could create problems?
Also, if in any of these frosting recipes I want to add some cocoa powder (or other similar ingredients) can I just add it or should I reduce for the same quantity the icing sugar?
Thanks!
Chiara
Hi Chiara. Milk powder won’t work for my American buttercream sorry. For this recipe I have a chocolate version on the site. I think theres instructions in the post for how to make my cream cheese frosting into chocolate cream cheese frosting. It’s really very delicious! N x
Hi Nick! For how long can this be safely left at room temp once used to frost good? And after that for how long more in the fridge? Thanks!
Hi Chiara. This buttercream has a lot of sugar in it which acts as a kind of preservative. I think 2-3 days would be ok out of the fridge. In the fridge it can sit in there for up to a week. Just keep in mind, if it’s on top of cupcakes and in the fridge, cupcakes tend to dry quicker when theyre in the fridge so I would say if it’s on the cupcakes, 3 days in the fridge. Hope that helps!

How easy is it to add different flavourings/colies to this recipe?
Hi Paul! Adding colors is really easy. You just add a couple drops of food gel colouring (not liquid food dye) and mix it in. Hope that helps! N x
Hi Nick
Can i use icing mixture instead of icing sugar?
Hi Trang! You can use icing mixture, but keep in mind that it contains cornstarch, which can affect the texture slightly. It might make the frosting a little softer and less smooth than using pure icing sugar (powdered sugar). If you’re after a smoother, firmer result, I’d recommend sticking with icing sugar. Hope that helps! N x
Hi Nick, I have just made the recipe and yum. I added an extra 200g of butter plus another cup and a half of icing sugar. I need to cover 30 cupcakes with a fondant topper plus decorate so not piped as high as yours plus I have a five layer (six inch cake). Will this be enough?
Hi there, I have done the recipe which is amazing but added another 250g butter and about another cup and a bit of icing sugar. Would this be enough to cover 30 cupcakes and a 5″ cake with five layers?
Hi Danelle! Hi! So glad you loved the recipe! With the extra butter and sugar you added, you’ve definitely increased the batch size. That should be enough to generously frost 30 cupcakes or a 5-inch, five-layer cake, depending on how thick you go with the frosting. If you’re aiming to do both (the cupcakes and the cake), it might be a little tight, but if you don’t mind a slightly thinner layer, you could make it work. Let me know how it turns out! N x
Hello Nick! How should I soften the butter and warm the milk if I don’t have a microwave? I had the butter problem as well when I was making pie crust and unfortunately couldn’t make any successful attempts so i want to make sure I do everything I can to not mess this one up! Thanks!
Hi Bridget! No worries—there’s definitely a way to soften the butter and warm the milk without a microwave. For the butter, you can leave it out at room temperature for about 30-60 minutes until it’s soft enough to press a finger into but still holds its shape. If you’re short on time, cut it into smaller cubes to speed up the process. As for the milk, gently warm it on the stovetop over low heat—just until it’s lukewarm, not hot. Hope this helps, and good luck with the frosting! N x
First of all I just wanted to thank you for the wonderful recipe. I made it yesterday for my son’s birthday cake I followed your instructions exactly that way you listed. And let tell you it’s amazing and I don’t taste the butter cream sandy is very smooth and it holds its shape. Thank you again!!!
That’s so lovely to hear, Maricela. I’m really glad it turned out so smooth for you and that it held its shape well. Hope your son had a great birthday! N x
Hi!! I made this yesterday and it was absolutely amazing! Is there a way I can make this chocolate??
Hey Natalie! Yes, you can absolutely turn it into a chocolate version. Just mix in about 30 to 40 grams of sifted unsweetened cocoa powder at the end and beat until it’s fully combined and fluffy. If it thickens too much, add a splash of cream to bring it back to the right consistency. – N x
MAKE IT MAKE IT !
