Comparing Types of Buttercream Frosting

Learn the differences between the three most common kinds of buttercream: American buttercream, Swiss meringue buttercream, and Italian meringue buttercream.


What is Buttercream?

Buttercream, in its most simple form, is a mixture of butter and sugar that has been creamed together to make a fluffy frosting. Buttercream is used for filling, icing, and decorating cakes and pastries.

It is no surprise that the fat in buttercream is typically all butter, which is where the name comes from. However, some buttercream recipes do call for other fats, like shortening, to create a more stable style of buttercream called decorators buttercream.

Types of Buttercream

There are a variety of styles of buttercreams all varying in their degree of difficulty to make. Each style of buttercream has different pros and cons as well as best uses in the pastry kitchen.

There are three types of buttercreams that are most often used: American Buttercream, Swiss Meringue Buttercream, and Italian Meringue Buttercream.

General Buttercream Guidelines

  • To properly cream the butter to form the buttercream, the butter must start at room temperature. If the butter is too cold, the emulsion might break causing a separated buttercream.
  • Buttercream is a blank canvas that can be flavored with virtually anything such as extracts, spices, melted chocolate, jams, and curds. As a general rule of thumb, the flavoring added to the buttercream should not exceed half the weight of the butter in the recipe.
  • If the buttercream will not be used right away it must be stored in the refrigerator. It will firm up quite a bit and should be allowed to come back to room temperature before piping or spreading.
  • Buttercream should always be served at room temperature. Because buttercream has such a high fat content, the texture will not be pleasant if eaten cold and will leave an extra greasy mouthfeel.

American Buttercream

American buttercream is the easiest buttercream frosting to make and the one most commonly used in non-professional kitchens. American buttercream is made simply by creaming together butter and confectioners sugar with milk or cream. If desired, vanilla extract or another flavoring may be added.

American buttercream is typically made from a ratio of 2:1 sugar to butter by weight. This ratio makes this style of buttercream the sweetest of all the styles.

American buttercream is also sometimes referred to as “crusting buttercream” because it forms a thin crust after exposed to air for some time, which can be desirable in some situations.

 Swiss Meringue Buttercream

Swiss meringue buttercream, also known simply as Swiss buttercream, is perhaps the buttercream most commonly used in professional pastry kitchens. This style of buttercream gets its name because it starts out with the process of making Swiss meringue.

Swiss meringue buttercream is somewhat more difficult than American buttercream because it involves a double boiler to heat the egg whites and sugar. This mixture is beaten into a meringue and then butter and flavorings are added.
