I love easy buttercream frosting (technically a mock Swiss meringue buttercream) because you don't have to heat any egg whites (thanks to pasteurized eggs), it tastes super creamy and not too sweet and only takes 10 minutes to make! You can pipe with this, use it under fondant and it tastes SO much better than store-bought! I promise anyone can make this!
This buttercream frosting is the recipe I WISH I had when I was making 5 wedding cakes a weekend. Now it's the only buttercream frosting I use and my clients love it. Way better than the super sweet frosting I was used to seeing on cakes.
EASY BUTTERCREAM INGREDIENTS
You might be like, egg whites... in frosting? What? It wasn't until I went to pastry school in 2010 that I first heard about different types of buttercream. Many types of buttercream, like Swiss, Italian, and French have eggs in them. The egg is often whipped into a light and fluffy meringue and then softened butter is whipped in. When you use meringue as your base for buttercream, you don't have to use as much sugar resulting in a light, fluffy, and less sweet buttercream that tastes a lot like ice cream. YUM!
Easy buttercream is similar to Swiss Meringue Buttercream except that you do not have to heat egg whites and sugar, whip to a meringue, let cool, etc. Thanks to pasteurized egg whites, you can skip to the whipping stage and no need to mix to a meringue! The taste and texture of easy buttercream is nearly identical to traditional SMBC. Did I mention this was easy?
WHAT ARE PASTEURIZED EGG WHITES?
Depending on the country you are in, you may or may not have access to pasteurized egg whites. In most places, they are found in a box in the egg section. The word "pasteurized" will be on the box somewhere, usually very small.
Pasteurizing is the process of gentle heating to kill food born illnesses and make a product safe to drink or eat. Many things are pasteurized, such as orange juice, milk, and wine. Pasteurized egg whites are safe for anyone to eat.
If you can't find pasteurized egg whites you can pasteurize them yourself and just use the egg whites or you can use my Swiss Meringue Buttercream recipe instead.
EASY BUTTERCREAM STEP-BY-STEP
Step 1– Place pasteurized egg whites and powdered sugar in a stand mixer bowl. Attach the whisk and combine ingredients on low, then whip on high for 1-2 minutes to dissolve the powdered sugar. You do NOT need to whip to a meringue.
Pro-tip – In traditional SMBC, fresh egg whites and granulated sugar are cooked together to dissolve the sugar and cook the eggs. We skip this step by using pasteurized egg whites and powdered sugar.
Step 2 – Add in your salt and vanilla extract. You can also substitute any other extract flavoring that you like, I love lemon or orange extract. Using clear vanilla extract will result in a whiter finished buttercream.
Step 3 – Add in your softened butter in chunks and whip with the whisk attachment on high. If you are using pasteurized egg whites from the fridge then you might notice this rim of cold butter forming. This is normal and can easily be fixed.
Simple stop your mixer and remove about ⅓ cup of the buttercream. Melt this in the microwave for about 20 seconds or until it's just barely melted. You don't want it hot!
Pour the mixture back into your whipping buttercream and the warmth from the melted buttercream will cause it all to come together and get creamy. This is honestly easier than taking out the egg whites ahead of time and trying to bring them to room temperature (at least for me).
Step 4 - Now let the buttercream whip until white and fluffy. This will take 8-10 minutes with a KitchenAid, but taste it to see when it's done. When it no longer tastes like butter and is sweet like ice cream, it's done!
Pro-tip – If you want your buttercream super smooth, double the recipe so that the buttercream level is above the whisk attachment. As the buttercream whips, it works out all the bubbles so you get a super smooth buttercream with no bubbles.
Step 5 – (Optional) To make your buttercream extra white, use the end of a toothpick to add in a TINY drop of purple food coloring and about 1 tablespoon of white food coloring. The purple will counteract the yellow in the butter and make it super white. Mix together.
TIPS & FAQ
BUTTER SUBSTITUTES
Using good quality, real butter is best, but you can substitute it with margarine, vegan butter, or vegetable shortening. I can't guarantee the taste will be the same, but you can use whatever is your preference!
WHY IS MY BUTTERCREAM SPLITTING?
The buttercream splits because it's too cold. Take out ⅓ 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.
MY BUTTERCREAM IS TOO SOFT, WHAT CAN I DO?
Buttercream is soft or firm depending on how warm it is. If it's too soft, it could be 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.
WHY IS MY EASY BUTTERCREAM GRITTY?
Some people have said their buttercream has a grainy consistency, but I have never experienced this before. If you have this issue, try sifting your powdered sugar before adding in the pasteurized egg whites and mixing the egg whites with the powdered sugar on medium for 5 minutes to dissolve the powdered sugar.
IS THIS GOOD TO USE UNDER FONDANT?
YES! I do all the time, just make sure to chill your cakes until the buttercream is firm to the touch before applying fondant. It goes great with my homemade marshmallow fondant too! Check out my video on how to cover a cake in fondant.
HOW STABLE IS THIS FROSTING?
This frosting will not crust, but is stable enough to pipe buttercream flowers 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 is more stable than cream cheese frosting or whipped cream.
You can also make a white chocolate buttercream frosting by adding melted white chocolate into the buttercream frosting. This makes a SUPER stable buttercream frosting that is a combination of buttercream and white chocolate ganache.
HOW LONG DOES THIS BUTTERCREAM LAST?
Easy buttercream will last for 2 days at room temperature, 2 weeks in the fridge or 6 months in the freezer. If your buttercream is cold, make sure to whip it up again before using it. Bring your buttercream to room temperature and begin whipping it. Then remove ⅓ cup of the buttercream and microwave it until it's just barely melted, then pour it back in while whipping to make it smooth again.
If you're going to frost your cake tomorrow, just leave the buttercream on the countertop. You don't have to refrigerate it within 2 days because the butter and sugar act as its own preservation.
If your buttercream frosting has been sitting at room temperature for more than a day, mix it with the paddle attachment before using it to make it smooth again. Buttercream tends to get spongy after 24 hours and loses its creamy texture.
HOW TO COLOR EASY BUTTERCREAM
You can add a few drops of gel food coloring to this buttercream to color it. It holds color well and gets darker overnight. Just be sure to not add too much food coloring or you'll be able to taste it.
If you want to make darker colors, check out my neon buttercream blog post for more information.
ARE PASTEURIZED EGG WHITES SAFE TO EAT?
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.
CAN I ADD MORE/LESS SUGAR?
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.
HOW MUCH FROSTING DO I NEED?
This easy buttercream frosting recipe makes about 6 cups which is enough to frost and fill a three-layer, 8" round cake. You can use the frosting and cake batter calculator below to adjust the amount of frosting you will need depending on the size cake you want to make.

Recipe

Ingredients
- 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
- 24 oz powdered sugar sifted if not from a bag
- 2 teaspoon vanilla extract
- ½ teaspoon salt
- 6 oz pasteurized egg whites room temperature
- 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.
Macaron lover says
This is amazing!! So much better than ABC!
Can I use this as a filling in between macaron shells? If so, what stage would I add the flavoring? Do you have advice for infusing cooled tea (like infused thai tea)? I usually add it to a ganache but would like to try it with this recipe if possible. Thank you 🙂
Elizabeth Marek says
Yes you can use it as a filling, you can add flavoring at any time. I'm not sure about flavoring with tea but you could add flavored ganache to the buttercream.
Linda Ghanbari says
In reply to christi Brooks I am also in the UK. Cartons of pasteurized egg whites can be found in all the major supermarkets in the chilled section with the butter and marg. The two main brands in the uk are 3 chicks, and the happy egg co liquid egg whites. They come in 500g cartons.
Hope this helps. Also if a recipe calls for shortening it is TREX in the uk, also found with the butter and marg x

Hi Liz I was wondering if I could freeze this frosting recipe after I made it? Would it still be okay to use or will it be ruined? Thanks for your help 😊
Elizabeth Marek says
Yes you can freeze it
Chanel says
Liz...
GIRL...
Heavy and JOYFUL sigh!!!!!! OMGoodness dang GRACIOUS.
Where Swiss Meringue Buttercream (for me) is the Mercedes of allllll — YOUR recipe HAS GOT to be the Cadillac of an ‘unorthodox’ Buttercream.
This here is balanced extreeeeeeemly well.
EXTREMELY.
I typically use the Avalon’s version which, while I like it...it is indeed a bit too buttery. Good....but too buttery. It’s an unfortunate case with most buttercreams.
That’s coming from a chick that digs butter and sugar.
SugarHero’s...yeah it’s better but THIS stuff here— when I tasted it.... mannnn... I literally leaned my forehead head against my upper cabinet door and LITERALLY shouted...
“LORD...That’s tasty goodness right there!!!!!”
And (which I was skeptical of) it uses LESS precious butter.......!
How dare I question a buttercream and cake wizard???
What was I thinking?! Your Butter Cake recipe is a favorite of mine.
Girrrrrrl.
All I can say is...put some insurance on that cape, brain and hands you got.
This here is:
A BEAUTIFUL CADILLAC.
Elizabeth Marek says
Lol best comment of the day. Thank you!
Keila says
Hey Liz!! I love your content and have read this post up and down! I am decorating a cake this weekend with your easy buttercream and was reading that if can split if it’s too cold. if my cake is already decorated and frosted, should i still refrigerate it? will it hold up? This may sound silly, but i just want to make sure the cake and the frosting will be okay! Thanks!
Elizabeth Marek says
Splitting only happens during mixing if the egg whites are cold. It won't split on a cold cake and yes you can refrigerate it.
Arasie says
Hi dear can i add some strawbery n lemon emulco to the buttercream frosting since its a unicorn design cake. Ive baked a strawberyy cake n wanted to frost it wit strawberry flavour buttercream.
Elizabeth Marek says
Yes you can add flavoring to the buttercream
Cicely says
Do I still have to make sure that there is no grease in the bowl before I add the egg whites to the bowl?
Elizabeth Marek says
No you dont
Dena says
Idk why I have such a hard time with this. Is it ok to still look like egg whites not beaten after whipping for 10 minutes?
Elizabeth Marek says
I dont understand what you mean. How can it look like un-beaten egg whites if you're whipping it?
Hiba says
Hey, will this buttercream stay stable under the fondant?
And, in my area, we don't have egg whites separately available, so how many eggs would i need to use?
Can i use freshly seperated egg whites instead?
Elizabeth Marek says
You can only use pasteurized eggs for this recipe, you can use my swiss meringue buttercream recipe for regular egg whites. Yes you can use this under fondant.
Dena says
I was worried because they don't whip like unpasteurized egg whites, but after having faith and completing the recipe to the T, it turned out great. 🙂
Deanna says
Hi!
When you say room temperature for your butter and egg whites, how long do you leave them out of the fridge?? Some resources say 30 minutes, some say overnight, others say anything in between.
What do you do??
Elizabeth Marek says
As long as it takes to make the ingredients room temperature, you have to go by how it feels.
Mariah says
Is this recipe okay to double? I ask this question because in some recipes your able to but in some recipes not so much thank you for your help again. + your recipe is amazing 😉 and taste way better than any other butter cream I’ve tasted and is literally fool proof!
Elizabeth Marek says
You can double, triple, whatever you want

Hi, Can I use Nuttelex (dairy free butter substitute) instead of butter because of dairy allergy?
Elizabeth Marek says
Yes you can but it might be softer than usual
Shuqing says
I made this frosting to cover my white velvet cake. I left the cake out overnight and I woke up to a melted cake (the frosting). I don't know what I did wrong. Can you really leave the frosting at room temp?
Elizabeth Marek says
Yes you can unless your house was very very hot (over 80ºF)
Elizabeth I says
Liz, love this recipe; so easy and fantastic. I have several go-tos for a honey frosting but was curious if there is a good proportion of honey to swap into your recipe or add to make it into a honey frosting, since I enjoy this recipe.
Didn't want to waste a bunch of frosting to experiment and thought it might be worth an ask before I circle back to my go-tos. Thanks!
Elizabeth Marek says
Oh that sounds really yummy! I've never made a honey frosting but I would probably start with only a Tablespoon and only add a small amount so that the honey did not soften the buttercream too much
Elizabeth I says
Thank you! Good to have a starting point suggestion 🙂 Much appreciated!
Maryam says
What do I do if the cream taste way to much like butter ?
Elizabeth Marek says
Keep on whipping. It will taste like ice cream when its ready
uma g says
can i use this recipe for oreo buttercream? If yes, at which stage do i add in the powdered oreo?
Elizabeth Marek says
You can add it in at the very end once it's light and fluffy
Courtney Peters says
This is amazing!! After a completely failed attempt at Swiss and Italian buttercream, 3 American buttercreams that I couldn’t stand the sweetness of, and Russian and Ermine buttercreams that just weren’t for me.. THIS IS THE WINNER!! I absolutely love this recipe so so so much. I am a novice who basically can only bake the cake layers - everything else is a disaster for me and I pulled this off on the very first shot! I loved the taste, and I was so excited to get such a smooth and silky buttercream I almost cried!!
My hubby liked the buttercream but asked if I could sweeten it a little bit. Would it severely throw off the recipe if I added a few extra tablespoons of powdered sugar?
Thank you so much for creating this recipe - I am in love!
Debbie says
How is the uncooked egg whites ok to eat. Is it safe for pregnant women to eat? I started using meringue powdered to replace the raw egg whites. It’s close to SMB and I feel safer using it.
Elizabeth Marek says
Pasteurized eggs are heat-treated and 100% safe to eat, just like drinking pasteurized milk. Meringue powder is not the same. If you want to heat the egg whites to make SMBC that is literally the same as pasteurizing egg whites. I hope that clears it up for you.
LIset says
HI Liz, love this frosting, but, it,s super super running, i have done it twice, i'm new doing all these, i don,t know what i did wrong, really appreciate your help
Love your tutorial, love your personality, thanks
Elizabeth Marek says
I'm not sure, are you weighing all your ingredients ore you converting to cups? Making sure you're using the right amount of powdered sugar
Caitlin says
Hi! Can I make this a base recipe and then later split it up and use it to make the whites chocolate version, lemon version, etc? Just let it come to room temp and add the lemon curd or cooled white chocolate and mix with the paddle?
Elizabeth Marek says
Yes you can split it up any way you want and flavor it differently
Juby says
How do you color it? Can I use gel based coloring?
Elizabeth Marek says
