This easy vanilla buttercream recipe is my go-to American buttercream for cakes and cupcakes. It’s rich, creamy, full of vanilla flavor, and less sweet than traditional American buttercream thanks to the perfect balance of butter, powdered sugar, vanilla, and salt. It has a smooth, spreadable consistency that’s ideal for filling and frosting layer cakes, topping cupcakes, and piping intricate designs. It also firms up in the refrigerator, making it perfect to use as a frosting base under fondant!


One reader, Iqra, says: “I LOVE this recipe, I have been making buttercream for some time now but I wanted to see if I could make it better, creamier and less sweet. And this recipe was just that! It was so creamy, light, fluffy and the perfect amount of sweetness. Best recipe I have found!” ★★★★★
I’ve tested countless buttercream recipes over the years, and this is the vanilla frosting I come back to again and again. It’s simple enough for beginner bakers but versatile enough for detailed cake decorating, and you can easily adjust the consistency depending on how you plan to use it.

Why You’ll Love This Vanilla Buttercream
- Beginner-Friendly. No cooked sugar, egg whites, or complicated techniques necessary here. This vanilla buttercream comes together in minutes with a stand mixer or hand mixer.
- Less Sweet. This recipe uses less powdered sugar than the average American buttercream and balances the sweetness with salt.
- Perfect for Cake Decorating. The consistency of this buttercream is ideal for filling and frosting layer cakes and decorating cupcakes. You can easily adjust the consistency to make it thinner or thicker depending on what you need it for.
- Strong Vanilla Flavor. You can use vanilla extract or vanilla bean paste here, either way you’ll end up with amazing vanilla flavor.
- Easy to Make Ahead. You can make this vanilla frosting up to two weeks ahead of time stored in the refrigerator, or up to two months ahead if you want to freeze it.

Vanilla Buttercream Ingredients
There are just a handful of ingredients you’ll need for this recipe and it’s simple to whip up for people of all skill levels. I’ll explain what role each ingredient plays in the buttercream and any substitutes you can use:
- Unsalted Butter. This is the base of the buttercream and gives the frosting a rich buttery flavor and velvety smooth texture. If you only have salted butter on hand, you can use that instead and omit the salt at the end of the recipe. And if you want a vegan version of this buttercream, you can follow this recipe which uses vegan butter sticks.
- Powdered Sugar. This adds stability to the frosting while sweetening. I like to use less powdered sugar than the average American buttercream so that the frosting doesn’t end up cloyingly sweet, but if you’d like it even less sweet you can reduce the powdered sugar amount by up to ½ cup (60g). Just keep in mind that the consistency of the buttercream will be thinner.
- Vanilla. You can use either vanilla extract or vanilla bean paste to flavor the buttercream, and making sure you use a quality brand is one of the secrets to success. You can use any kind of vanilla extract or paste, but my favorite brands are Trader Joe’s and Kirkland Signature (from Costco) for vanilla extract, and Nielsen-Massey for vanilla bean paste. If you’re looking for more flavor options, I have all of my frosting recipes here.
- Milk or Heavy Whipping Cream. This thins out the buttercream while binding all the ingredients together. I like to use a liquid with lots of fat for this part because it makes the final frosting more velvety smooth, so whole milk or heavy whipping cream are my go-to’s. If you’d rather use a dairy-free option you can substitute this with any milk alternative, but keep in mind that the flavor of the liquid will affect the overall frosting flavor.
- Salt. A pinch of salt helps balance the sweetness beautifully.

How to Make Vanilla Buttercream
- Whip the Butter.
- Add the Powdered Sugar
- Add the Vanilla, Milk, and Salt.
- Mix Until Smooth.


How to Make the Right Buttercream Consistency
Depending on what you’re using this vanilla buttercream recipe for, you’ll want to consider the final consistency of the buttercream (in other words, how thick or thin it is). I have a detailed blog post on how to achieve the perfect buttercream consistency if you want additional resources. Here are the 3 types of buttercream consistency and what they’re best used for:
| Buttercream Consistency | Best For | How to Make It |
| Medium Consistency (the recipe as-is) | -Filling and stacking cakes -Crumb coating -Frosting a smooth buttercream finish -Piping a buttercream border -Piping swirls onto cupcakes | Follow the exact recipe below |
| Thin Consistency | -Piping a message with frosting -Buttercream painting -Getting a super smooth final coat of frosting (like what I use in this smooth buttercream hack) | Add one extra tablespoon of whole milk or heavy whipping cream at the end of the recipe |
| Stiff Consistency | -Piping buttercream flowers -Piping intricate designs that need to stand upright against gravity (like ruffles on a lambeth cake) -Piping a really sturdy buttercream dam before filling cakes with a soft filling. | Add extra powdered sugar to the recipe, about 2-3 tablespoons at a time, until the desired consistency is reached |
Vanilla Buttercream Tips for Success
This buttercream is simple for anyone to make, but there are a few things to keep in mind when making, storing, and working with it.
- Room Temperature Ingredients. Be sure to use room temperature ingredients. This is important for ingredients to combine and create a smooth consistency. Over the years I’ve found that cutting corners like adding cold milk will create a curdled look in the final frosting because the temperature hinders the ingredients from coming together smoothly. Not the best look! So, take your ingredients like butter and milk out of the refrigerator for about an hour prior to making the frosting.
- Use the Paddle Attachment on Your Stand Mixer. Also known as the flat beater attachment, the paddle attachment is designed to incorporate just the right amount of air into the buttercream. This makes it easier to make smooth buttercream without a ton of air bubbles.
- Whip the Butter for a Long Time. To achieve the smoothest buttercream that’s also nearly white in color, you’ll want to whip the butter for a long time – about 7 minutes. In this amount of time, the butter should go from yellow to almost white and be extra smooth.
- Then Mix Everything Else on Low Speed. After you whip the butter, it’s important to keep the mixer on low speed any time you’re mixing in the additional ingredients. Even though it will take longer to mix the ingredients, keeping the mixer on low speed helps prevent air bubbles from forming in the buttercream.
- Let the Ingredients Fully Combine. After I mix in the final ingredient (salt) I like to run the mixer on low speed for another minute or two to allow everything to combine fully. This gives the powdered sugar time to dissolve as well, so the buttercream will taste smooth and not grainy.

Vanilla Buttercream Troubleshooting + FAQs
- How much buttercream do I need to make for my cake project? It depends! I made this handy chart to help you calculate how many batches of buttercream to make for your specific cake size.
- How do I make my buttercream whiter? This buttercream is pretty white as-is from whipping the butter for so long, but to get it even more white, you’ll either want to add an icing whitener like AmeriColor Bright White or the tiniest amount of purple food coloring (it helps cancel out yellow hues).
- Do I need to sift the powdered sugar? It’s not absolutely required, but to get the smoothest texture for your buttercream, you’ll want to sift the powdered sugar.
- How do I get rid of air bubbles in my frosting? There are a few techniques! I detail them all in this blog post.
- Why is my buttercream grainy? Your powdered sugar isn’t fully dissolved. Keep mixing on low speed until it’s no longer grainy.
- Why does my buttercream look curdled? The most common reason is adding liquid (like the milk in the recipe) that is cold. This seizes up the butter content and creates a curdled look. To fix it, scoop out about ¼ cup of the buttercream and place it into a microwave-safe bowl. Heat it for 5-10 seconds, until it’s melted but not hot. Then, mix it into the rest of the buttercream to re-emulsify the separated fats and liquids.
- Why is my buttercream too thin? This recipe will end up thinner than usual if you start with butter that is too soft or your kitchen environment is too warm. In either of these cases, refrigerate the whole bowl of buttercream for 15-20 minutes to let the butter re-solidify slightly, then re-mix with your stand mixer on low speed until smooth.
- Why is my buttercream hard to spread? Sometimes after storing buttercream, it can thicken naturally and become hard to spread when you’re frosting a cake. In this case, I recommend re-mixing on low speed with your stand mixer and adding 1-2 teaspoons of room temperature milk until the consistency is silky and easy to spread.
- How do I store buttercream? Place the buttercream in an airtight container and store at room temperature for 1-2 days, or in the refrigerator for up to 2 weeks. When you’re ready to use it, bring it back to room temperature and re-mix with your stand mixer on low speed until smooth. You can also freeze buttercream in a Ziploc bag for up to 2 months, then thaw it in the refrigerator overnight before bringing it back to room temperature and re-mixing until smooth.

Hi Whitney,
Thanks a lot for the recipe and the tips! I’m planning ok making a 9 inch wide and 4 inch high round cake, is one recipe of buttercream enough to make a crumb coat and frost the cake?
Love from Germany,
Zoe
Hi Zoe! One batch of this buttercream will be enough for crumb coating and frosting a cake of that size. If you want to use it as a filling as well, I would double the recipe. Enjoy!
Can a frosted cake with this buttercream sit at room temperature or does it need to be refrigerated?
Hi Kathy! A frosted cake can sit at room temp for 3-4 days – the sugar in this recipe preserves the little amount of dairy in it, making it totally fine to leave out. I usually store mine in the refrigerator to preserve the details and remove it from the fridge about an hour or two before serving to bring it to room temp (cake always tastes better at room temp), but you can totally just leave it out of the fridge if you want to!
Hello. Can I use this buttercream for crumb coating.?
You certainly can, Diana!
What is the filling you use on your video for smooth buttercream? Could I use a ziplock bag as a piping bag to put frosting on cake?
Hi Kathy! This basic vanilla buttercream recipe is the one I’m using in the video for smooth buttercream. And yes – a ziplock would work fine in a pinch, but I do recommend getting actual piping bags at some point if you find yourself decorating cakes regularly.
Hi,
Will this vanilla buttercream recipie be enough to coat and crumb coat a 6inch cake?
Thank you x
Hi Sara! I would double the recipe if you plan on filling the cake with this buttercream as well as crumb coat and frost it. If you’re just crumb coating and frosting, one batch will be just fine.
Hi Whitney! Thanks so much for the recipe. I was wondering if I can substitute Swerve Confectioners for the powdered sugar and still have the same consistency. Thank you!
Hi Carolyn! I have never tried substituting the powdered sugar in this recipe, so I am not sure how it will turn out but you are certainly welcome to experiment!
Hi Whitney! I have a problem…the powdered sugar does not dissolve with the butter. The buttercream is grainy. How can I prevent this? Thanks a lot!
Hi Catalina! Usually when the buttercream is grainy it’s either because the powdered sugar needed to be sifted. If you did sift the powdered sugar, then check to see that the milk was room temperature (if it’s too cold, it won’t properly dissolve the sugar) and give it a little more time to mix at the end of the recipe so that the sugar has a chance to dissolve. Keep the mixer on low speed and mix for a minute or two and that graininess should be gone! Hope that helps!
Thank you so much!
Hey Whitney
How much would I need to crumbcoat and add extra decorations such as flowers etc to a 2 layer 8 inch cake?
Hi Fizza! I would double the recipe to have enough for crumb coating and adding floral decorations to a cake of that size.
For the crumb coat and frosting for 3 6’layers cake how much of this needed?
Hi Chathurya! For crumb coating and frosting a cake, this recipe will be enough as-is. I recommend doubling it if you’re planning on using it as a filling as well.
Hi, I made your cake for my birthday and it tasted amazing so I’m gonna make it again this time I just want to add whipped double cream and chocolate between the layers instead of buttercream so how much will I need to just frost the outside and pipe on top? Like shall I just make this much? Half it? Just let me know xx
I’m so happy to hear that, Sanah! To make enough of this frosting for frosting the outside of the cake and piping on top, I would just make this recipe as-is.
Thank you Whitney
Do you have a video/blog on storing buttercream?
Hi Corina! I don’t have a video or blog on that, but here’s what I do: I place the buttercream into an airtight tupperware container and store it in the refrigerator for up to two weeks, then when I’m ready to use it I put it out on the counter for a few hours to bring it to room temp. Then, I put it back into my stand mixer and mix on low until it’s smooth. Hope that helps!
Which do you think made the buttercream better the milk or the heavy whipping cream?
The buttercream tastes the same whether you use milk or heavy whipping cream, but the heavy whipping cream makes the frosting a little bit thicker. Hope that helps!
This is my fav buttercream recipe but was wondering do you think you could you add melted white chocolate to this?
Hi Becki! So happy you love this buttercream recipe. I already have a white chocolate buttercream recipe on my blog here: https://sugarandsparrow.com/white-chocolate-buttercream-recipe/ that is what I recommend if you want to make a white chocolate flavored buttercream. Enjoy!
Hi As daft as it sounds I wondered if this would change the way the buttercream comes out if only mixing by hand. Or would you suggest to use an electric mixer? Thank you
Hi Kim! I definitely recommend mixing with an electric mixer just because it would be near impossible to whip the butter without an electric mixer of some sort (hand mixer or stand mixer).
Thank you so much, i’ve learned a looot with your blog
Lots of love from Brazil!
Yay, Amanda!! That makes me so happy!!
