What is Italian buttercream?
It is often called IMBC, its small diminutive which means: Italian Meringue Butter Cream.
A buttercream containing a meringue with the technique called Italian meringue. A syrup of sugar cooked at 244°F / 118°C and incorporated into the whites, which gives a firm, smooth and shiny Italian meringue.
I very often use Italian meringue to make the shells of macarons or to decorate a pie such as lemon meringue tarts.
This frosting is similar to other meringue buttercreams, like the Swiss meringue buttercream or the French meringue buttercream.
Why choose Italian meringue buttercream?
- It's delicious, sweet, soft and creamy!
- It keeps its shape! And it's great for decorating cupcakes.
- It is stable at room temperature, an ideal cream for wedding cakes and birthday cakes that remain exposed for long hours.

Useful tools to make this recipe
- Stand mixer, although it is possible to make it with an electric mixer. (for small quantities) I strongly advise to use a stand up robot to make this cream.
- A cooking thermometer is essential to reach the right temperature of the syrup and obtain a nice Italian meringue.
- Egg yolk separator, useful to separate the whites from the yolks.
Ingredients notes
- Egg whites, at room temperature without any traces of yolk, otherwise the risk of missing the meringue is greater.
- White granulated sugar, do not use whole sugar or confectioners sugar.
- Unsalted butter, at room temperature, but not too softened either.
- Pure vanilla extract, to flavor the butter cream.
- Pinch of salt, as a flavour enhancer and helps to whisk the whites to snow.

How to make Italian buttercream ?
- Make the syrup: Heat the water and half of the sugar in a saucepan and check with a candy thermometer the temperature that must be reached 230°F/110°C.
- Whisk the egg whites: When the candy thermometer reads 230°F/110°C, place the egg whites with the pinch of salt in the mixer bowl and whisk at medium speed.
- Add the sugar to the egg whites: When the egg whites are frothy, add the other half of the sugar and mix at high speed.
- Stir in the syrup: When the syrup temperature reaches 244°F/118°C, reduce the speed of the mixer and pour the hot sugar syrup on the side of the bowl over the egg whites.
- Whip the meringue: And resume mixing at high speed to whip the meringue until the meringue has stiff peaks, firm, smooth and glossy. (duration = about 10 minutes)
- Add butter and vanilla: Finally, while letting the mixer run, add the soft butter and the liquid vanilla extract.
- Finish by letting the whisk rotate until a smooth and homogeneous white cream is obtained.

How to Store Meringue Butter Cream
It can be kept in the fridge preferably for about 1-2 weeks.
Also it is stable at room temperature without sanitary risk for 48 hours in a chill place.
And you can keep it in the freezer for up to 3 months.

Swiss Meringue Butter Cream vs. Italian Meringue Butter Cream
No big difference between these two creams, except that the Italian version contains more butter. This makes it smoother with prettier shapes and catches the light even more. For me it is the cream to choose for decorating and icing cupcakes.
The Swiss meringue butter cream is most likely the favorite! It's easier to make, easier to use and perfect for smoothing out a layer of cake.
FAQS about Italian buttercream
- Recover a granular butter cream (sliced)
You will have this aspect of granular cream, after the addition of butter and after a passage in the cold, here is how to proceed:
During the preparation of the cream, after the addition of butter it takes this granular texture.
- Simply let the mixer turn until it takes back a homogeneous and smooth texture.
After a cold passage, the cream is like cold butter, if you try to whip it immediately it will slice.
- Warm the cream, in the microwave or in a bain marie (just a few moments just to soften the butter).
- And mix with an electric whisk.
- The butter cream is full of air bubbles.
The quick whisk mixing has incorporated air into the cream, to evacuate these air bubbles, here's how to do it:
- Before using the cream, mix it with the flat spatula of the food processor for 1-2 minutes at medium speed.
- And finish by mixing the cream with the spatula, spreading it over the edges of the bowl to smooth it.
- My buttercream is liquid
If your butter is too softened, or even melted, the cream will be too liquid.
- Place your cream in the fridge for at least 1 hour.
- And whisk the mixture again.
- How do I color my butter cream with Italian meringue?
- By adding food coloring gels.
How to flavor the butter cream
