What are the two types of frosting?

There are many different types of frosting, but the two most common categories are:

* Buttercream frosting: This is a classic frosting made with butter, powdered sugar, and often milk or cream. It comes in many varieties, including American buttercream, Swiss meringue buttercream, and French buttercream.

* Cream cheese frosting: This frosting is made with cream cheese, powdered sugar, and often butter or milk. It is often used on cakes and cupcakes.

These two types of frosting are popular because they are versatile and can be easily flavored and decorated.
