Why This is My Go-To Recipe
The secret to this easy buttercream is using pasteurized egg whites and powdered sugar as the base, then whipping in butter to create a silky frosting that has a texture very similar to Swiss meringue buttercream but without heating the egg whites. It pipes beautifully, spreads easily, and works perfectly for cakes, vanilla cupcakes, and even under fondant covered cakes.
This frosting is my go-to for my easy chocolate cake recipe - simple, reliable, and always a crowd-pleaser.
When I first started decorating cakes professionally, I used the traditional super-sweet American buttercream that most beginner decorators learn first. It was easy to make, but I always felt like it tasted way too sugary and heavy on my cakes. Plus, it was really hard to get smooth!
I came across this buttercream recipe from Lauren Kitchens, and it revolutionized how I make buttercream. I realized there was a way to get the smooth, silky texture of Swiss meringue buttercream without having to cook egg whites or deal with a complicated meringue process. Start with pasteurized egg whites, which are already (pre-cooked), add in the sugar, butter, salt, and vanilla, and boom! Done!
I tweaked the original recipe because I thought it was too buttery, but that's where this easy buttercream recipe came from. It's become my go-to frosting for cakes because it's simple, pipes buttercream flowers, cupcake flower bouquets, rosettes, and vintage piping beautifully.
Easy Buttercream Ingredients
This easy buttercream frosting uses just a few ingredients, but each one plays an important role in creating the smooth, creamy texture. Always make sure your cold ingredients, like the egg whites and butter, are at room temperature.
Pasteurized Egg Whites create the base for this easy buttercream. When whipped together with powdered sugar, they form a light and stable mixture that helps give the buttercream its silky texture. You can find pasteurized egg whites in the refrigerated section with the eggs.
Powdered Sugar is used in this recipe for sweetness and structure. Make sure you are using powdered sugar from cane sugar, not from beets. Beet sugar can sometimes end up tasting gritty.
Unsalted Butter is needed for this recipe. If you only have salted butter, you can still use that, but I would use half butter and half vegetable shortening so your buttercream doesn't end up being too salty. You can also replace the butter with any type of vegan butter that you like.
Vanilla Extract adds classic buttercream flavor and rounds out the sweetness of the powdered sugar. You can pretty much use any kind of extract flavor you like instead of vanilla. Just keep in mind some extracts like almond or peppermint are stronger than vanilla, so decrease or increase amounts as needed. My favorite vanilla is Nielsen Massey.
Salt balances the sweetness and enhances the overall flavor without making the frosting taste salty.
How to Make Easy Buttercream Step-By-Step
- Combine pasteurized egg whites and powdered sugar in the bowl of a stand mixer fitted with the whisk attachment. Whip the mixture on medium speed until it becomes thick and glossy.
This creates the base for the easy buttercream.
- Begin adding softened butter one piece at a time while mixing on medium speed.
At first, the mixture may look curdled or separated. This is completely normal.
- Mix in the vanilla extract and salt. Then whip on high until light, fluffy, and no longer tastes like butter.
- Optional: Switch to the paddle attachment. Mix the easy buttercream on low for several minutes to remove air bubbles and achieve the smoothest possible texture.

BONUS TIP:
If your buttercream looks curdled and is sticking to the sides of the bowl after adding the butter and whipping, don't panic. Remove 1 cup of the frosting and heat it in the microwave until just melted but not hot. Mix it back into the frosting. The extra warmth helps the buttercream become smooth.
Common Problems & How To Fix Them
Buttercream looks curdled: This usually happens right after adding the butter. Keep mixing, and the frosting will smooth out. If it's taking a long time, the butter or the egg whites could have been too cold. Remove 1 cup of the buttercream, melt it, and mix it back in.
Buttercream is too soft: Chill the buttercream for 10-15 minutes in the fridge. Mix before using to make it smooth.
Buttercream is too stiff: Remove 1 cup of the buttercream, melt it, and mix it back in, or you can use a heat gun or blow torch on the metal mixing bowl while mixing on low to warm the buttercream up slightly.
How Stable is Easy Buttercream Frosting?
Easy buttercream frosting will not crust, but is stable enough to pipe buttercream decorations and will last at room temperature for 2 days.
It is ok at temperatures up to 85ºF but will melt in direct sunlight in about 20 minutes, so keep it in the shade! You can replace half the butter with shortening to make it more stable in high temperatures.
Easy buttercream is not as stable as American or Italian buttercream, but it is more stable than cream cheese frosting or whipped cream.
You can also make a white chocolate buttercream frosting by adding melted white chocolate to the buttercream frosting. This makes a SUPER stable buttercream frosting that is a combination of buttercream and white chocolate ganache.
Final Thoughts
Easy buttercream is one of the best frosting recipes to learn if you decorate cakes regularly. It has a silky texture similar to Swiss meringue buttercream but skips the complicated steps, making it perfect for beginner cake decorators.
Once you master this easy buttercream recipe, you'll have a reliable frosting that works for cakes, cupcakes, and piping decorations. Pairs perfectly with my easy drip cake recipe
Easy Buttercream FAQs
Easy buttercream is a frosting made from pasteurized egg whites, powdered sugar, butter, vanilla, and salt that creates a smooth buttercream similar to Swiss meringue buttercream but without cooking the egg whites.
Yes. Easy buttercream tastes less sweet than traditional American buttercream because the egg whites and butter balance the powdered sugar.
Yes. Easy buttercream is excellent for piping decorations like rosettes, borders, and flowers.
Yes! Pasteurized egg whites are heat-treated (like milk), so they are safe to eat. They usually come in a box carton in the egg aisle. If you don't have pasteurized egg whites, then you can use my SMBC recipe instead. Note: undercooked egg whites are not recommended for pregnant women, just to be on the safe side.
This recipe is not very sweet, especially if you're used to American buttercream. You can add more powdered sugar if you want it to be sweeter, but you cannot reduce the sugar, or the buttercream will be too soft.
The buttercream splits because it's too cold. Take out 1 cup of the buttercream and melt it in the microwave until it's just melted, and then whip it back in. That little bit of warm butter helps it all come together again.
Buttercream is soft or firm depending on how warm it is. If it's too soft, it could be that your butter was too soft when you added it in, or the mixer warmed it up. Put the buttercream in the fridge for 20 minutes, then whip it again, and it should firm back up.
Yes. Easy buttercream is stable enough to use under fondant when properly chilled.

Recipe
Ingredients
- 6 oz pasteurized egg whites room temperature
- 24 oz powdered sugar sifted if not from a bag
- 24 oz unsalted butter room temperature. You can use salted butter but it will affect the taste and you need to leave out additional salt
- 2 teaspoon vanilla extract
- ½ teaspoon salt
- 1 TINY drop purple food coloring (optional) for whiter frosting
Instructions
- Place egg whites and powdered sugar in a stand mixer bowl. Attach the whisk and combine ingredients on low and then whip on high for 1 minute to dissolve the powdered sugar
- Add in your salt and vanilla extract
- Add in your butter in chunks and whip with the whisk attachment to combine. It will look curdled at first. This is normal. It will also look pretty yellow. Keep whipping.
- If your buttercream looks curdled, remove about ⅓ cup of buttercream and melt it in the microwave for 10-15 seconds until JUST barely melted. Pour it back into the whipping buttercream to bring it all together.
- (Optional) Add your drop of purple food coloring. Whip on high with the whisk attachment for 8-10 minutes until it's very white, light and shiny. Taste the buttercream, if it tastes like sweet ice cream then it's ready!
- Switch to a paddle attachment and mix on low for 15-20 minutes to make the buttercream very smooth and remove air bubbles. This isn't required but if you want really creamy frosting, you don't want to skip it.

Hi Liz,
Not sure if this question is already asked. If I bake the cake and cover with butter cream frosting a couple days before, do I just need to take the cake out of the fridge and immediately cover with fondant or do I need to wait until the cake warms up a little?
Sugar Geek Show says
You can cover the cake in fondant when it's chilled, it's safest to decorate with a cold cake 🙂
Amber says
If I wanted to add some marscapone to this frosting should I reduce some butter? My daughter loves the flavor so I wanted to incorporate it.
Elizabeth Marek says
Mascarpone doesnt have the same consistency as butter so you can't switch them out 1:1 but you could add some mascarpone to the frosting
Diane Barry says
Wonderful buttercream - delicious and not too sweet! Very clear and easy to follow instructions. I added some espresso powder to make an Espresso Frosting for the white cake recipe I found on this site. Everyone loved it!
Lauren P. says
I love this BC, thank you for sharing! Question: can it be toasted like swiss meringue?
Sugar Geek Show says
As far as I know, Swiss meringue buttercream and easy buttercream cannot be toasted like regular meringue can. The butter in it would melt.
Jo Ann says
Will this frosting be ok to use for piping and other decorations?
Sugar Geek Show says
Definitely! Check out my easy 5-petal buttercream flowers and how to make a wedding cake blog posts to see how it pipes 🙂
Sez says
Thank you for this recipe! It’s so easy and worked perfectly without thermometers and hot sugar ugh can’t rate it highly enough for the convenience. Mine was grainy because I used ‘Icing Mixture’ powdered sugar which in Aus also contains cornflour but totally my fault, should have used ‘Icing Sugar’ powdered sugar. Still excellent buttercream and will know for next time. Saved to favourites! Thanks again.
Devi says
Hiii dear, I simply love your recipes. Your tips on baking are fantastic. Can I know if I can use this Easy buttercream or your Swiss Meringue Buttercream as fillings for macarons?
Love to hear from you...
Sugar Geek Show says
Either work great with macarons!
Aimee says
AMAZING! This buttercream was so easy to make and delicious! Thank you so much for sharing this recipe with us. I’m already making a list of more recipes I plan to try from your site!
LaNae says
The BEST Buttercream ever! I loved it on cupcakes too! I would always make Italian buttercream when making my wedding cakes for the lightness, however as you know it is a little process. I have found the pasturized egg whites at Sams Club. Thank You so much for sharing with us, I love everything you do, such a great teacher!
Shana says
Hello, can you cover a cake in fondant over this buttercream?
Elizabeth Marek says
Yes you can
Rebecca says
Love this recipe!! I just have trouble getting all the air out. Even if I double the recipe, using the lowest setting on my kitchen aid mixer with the paddle attachment for 20 min, there is still a lot of air in the frosting. Any ideas why??
Elizabeth Marek says
You might have a bigger bowl. Make enough that the buttercream is covering the top of the paddle attachment.
Heather says
Hi Liz, I love your recipes and this one is so delicious too! My question is that 24 oz = 3 cups on my measuring cup but when I weigh this qty to double check, the scale only reads 12 oz. So should I use 6 cups of sugar?
Thanks,
Heather
Elizabeth Marek says
Do not go by your cups. Only measure by weight.
Alex says
Hi I’m just trying to get s knack to cake making. I’m going to try this on my daughters birthday cake coming up. Just curious would you suggest a ganache underneath or not necessary for basic cake but something you may do if it was more professional?
Elizabeth Marek says
Ganache is just a flavor choice 🙂 You could use it as a filling if you want or you could frost the whole cake in ganache. Its up to you
Silvia Rezende Campos says
At what point to add the melted white chocolate to the butter cream, to make a white chocolate butter cream? I was left with this doubt because the butter cream is cold and the melted chocolate is hot, or would it be a chocolate meringue?
Elizabeth Marek says
If you are adding chocolate you should wait until the chocolate has cooled to 88ºF and make sure the buttercream is room temperature or you could get lumps of chocolate
Heidi says
I tried this recipe and thought it worked out so great. I put it on the cake and put it in the fridge to chill. When I took it out to put on my final layer the frosting looks yellow. Now what?
Elizabeth Marek says
Yellowing can happen if you use heat to smooth your buttercream, essentially melting the butter.
Savannah says
What buttercream do you recommend for a semi-naked cake? I have to travel over 2 hours to deliver it. Also, do I need to keep it chilled any other way other than an air conditioned car?
Elizabeth Marek says
It doesn't really matter. You can even use ganache. I would stay away from cream cheese or whipped cream. As long as it's chilled and in a cold car you will be totally ok. I also place my cakes in boxes to keep the sun off them.
