Perfect Italian Buttercream Frosting is a rich, smooth, and incredibly delicious traditional icing that is the best choice to decorate cakes and cupcakes.
This is the same kind of buttercream frosting that you’ll find on many professional wedding cakes. Its silky texture is unlike any other frosting or icing recipe that you’ll ever find, it is gorgeous when piped, and can be flavored and colored in countless ways.
Why this recipe works:
When you consider how perfectly smooth, rich, creamy, and heavenly this buttercream frosting is and how incredibly easy it is to use for decorating, it will soon be one of your favorites.
- Italian buttercream is considered more difficult than traditional American buttercream only because you must get the hot sugar syrup to an exact temperature, but once you get the hang of this recipe it is actually super easy to make.
- This frosting is a decorator’s dream! It is incredibly smooth and creamy. When refrigerated it gets hard because of all the butter, which makes it perfect as a crumb coat before your final layer of frosting or fondant is added.
- Italian buttercream holds up really well at room temperature. You can use it to decorate both cakes and cupcakes.
- If you like a frosting that is rich and buttery and not too sweet, this is your kind of recipe!
Whether you use it for a dry crumb frosting base only before adding fondant and fancy decorations, or you cover the entire cake in buttercream frosting, it truly is one of the most gorgeous things you can put on a cake.
How to make my Italian buttercream:
- First step is to get the sugar mixture to the soft ball stage. This is done by heating the sugar and corn syrup in a pot over the stove. You must use a good thermometer to ensure it is the correct temperature.
- Next you will beat the egg whites. Once they begin to get foamy but soft peaks haven’t formed, you will add the hot sugar syrup.
- Then you will add the softened butter, one cube at a time.
- Finally, you will mix in the vanilla extract. If you’re wanting to color the frosting, this is when you would add the food coloring.
Cooking tips:
- You must get your sugar to the soft-ball stage which is 235 degrees F. I live close to sea level, so this is the temperature I go by. At high altitudes, water boils at a lower temperature. For example, at 4500 feet above sea level, water boils at 204° F. If candy is cooked until it reaches the soft-ball stage on a candy thermometer, it will have cooked too long.
- I add a bit of corn syrup to my recipe because it adds a beautiful sheen, but this can be omitted if you want to make a pure Italian buttercream recipe.
- I recommend mixing the egg whites while the sugar syrup heats up. Ideally you want them ready as soon as the sugar syrup hits it’s temperature.
- When you whip your egg whites, you want them to have a lot of air and a beautiful sheen, but do not let them get to the stiff peak stage.
- Remember to be patient. I’ve had a lot of readers who had this recipe turn out perfectly and others who couldn’t get it to work. Once you start adding the butter, it will look awful, but you just have to keep mix and just like magic, you will end up with the best buttercream frosting.
Different types of buttercream frosting:
If you’re like me, you probably grew up making what is considered American buttercream. As far as taste goes, that is still my preference, but some consider it too sweet.
If you didn’t realize there are different kinds of buttercream frosting, here’s a quick summary:
- AMERICAN: Powdered sugar + softened butter + milk + vanilla
- SWISS MERINGUE: Egg whites + sugar whisked together over boiling water and then beaten with butter
- FRENCH: Egg yolks + homemade sugar syrup + butter
- ITALIAN: Homemade sugar syrup + egg whites + white sugar + softened butter

Ingredients
- 1 1/4 cups granulated sugar
- 2 tablespoons corn syrup
- 5 egg whites approx 185g
- 1 lb unsalted butter softened
- 1 teaspoon vanilla extract
Instructions
- Add the sugar and corn syrup to a small saucepan, drizzle a few tablespoons of water over the sugar, and stir together until the sugar is all moistened. It will have a wet sand feeling about it. Cook the sugar over medium high to high heat to the softball stage of 235 F using a candy thermometer. Use a pastry brush to lightly water down the inner sides of the sauce pan to prevent crystallization. When the sugar is done, turn off the burner (if gas), or move the pan off the burner (if electric).
- Begin to whip your egg whites with a whip attachment in a stand mixer. When the meringue begins to look opaque, but is not to any sort of ‘peak’ stage yet, slowly pour the cooked sugar syrup down the side of the mixing bowl, as the mixture is whipping on a medium speed. Allow the mixture to whip until glossy medium peaks form and the meringue is cool to the touch.
- Turn the mixer on a low speed, and add the butter, one stick at a time. Be sure meringue is cool to the touch first so that the butter doesn't melt! Mix until the mixture comes together. Don't be scared! The mixture will separate and look terrible before it comes together again, which It will- I promise. Be patient.
- Once the mixture is smooth and wonderful-looking, add the vanilla and whip just until combined.

Krissy, this buttercream sounds fantastic and I loved the links to the marshmallow recipes. I’ve never made those and I would love to try it sometime!
Very helpful and detailed post about buttercream. Thanks for sharing!
How long does it take to come together. Mines looks like liquid pudding
This really is a perfect buttercream frosting! My fave <3
Thank you so much for this recipe. I’m printing it and am planning on using it for a sandwich cookie I will be making.
What brand/model of candy thermometer did you use? I need a new one and am looking for recommendations.
Hi Susan, Not sure if this is wrong or right, but I use a regular baking thermometer instead of a candy thermometer. This is the one I’ve used for years and it has never failed me: https://amzn.to/2L2yZvj
What about adding liqueur for flavoring? Would you use the same amount as you would vanilla? Iโm thinking St. Germain.
I would start with a small amount, taste, and increase from there. Different liqueurs and extracts pack different kinds of punch!
Made this recipe exactly as written and it came out perfect, thanks!
Can I add some flavor to the Italian buttercream recipe????
Absolutely! If you’re adding flavored extracts, just start small, taste, and add more as needed!
Hi Krissy, Can I use liquid egg whites to replace fresh ones? Thanks
You bet!
I went to school for baking and pastry and I remember making a recipe like this in school so I found it pretty easy, Definitely not a beginner recipe. I donโt think 1 1/4 cup is near enough sugar because it tastes like a Whipped butter. Will make again but I will do at least 2 cups of sugar
It definitely has a strong butter taste. I think this recipe is best as a decorating frosting and not so much a “shove in your face and lick your fingers” frosting. Would love to know your results with more sugar!
I made both the normal and the chocolate version. I must say, this is definitely not your beginners frosting. It takes some getting used to. But, if you can pull it off… which I did by my 3rd attempt… it is certainly a crowd-pleaser! MAKE SURE YOU LET THE SUGAR/EGG MIXTURE COOL DOWN BEFORE ADDING BUTTER!!! I can’t stress this enough. If you add butter while it’s still hot, the butter melts and you have a melty-soupy mess. It still comes together after what seems like 45 minutes of mixing… but not as well as if it was cooler. IF you messed up and melted the whole batch, I found mixing it until it came together somewhat and solidifying the butter again in the refrigerator at least an hour or over night… then whipping it back up again for around 15-20 minutes fixed my melted mess!
I love this frosting, but I would love to make it into chocolate frosting! What is the ratio of melted chocolate to the rest of the mixture?
I’ve never added chocolate to this recipe. Sorry!
