Creamy Peanut Butter Frosting

Does peanut butter frosting need to be refrigerated?

It is not necessary to refrigerate this peanut butter frosting. The small amount of milk in the recipe (1/4 cup) is stabilized by the large amount of sugar and considered safe at room temperature for two to three days.

Always refrigerate any cake with a frosting that contains eggs or egg whites. Also be sure to refrigerate any kind of frosting that is whipped-cream based or cream cheese frosting.
