How Long Can Buttercream Sit Out: Proper Storage And Shelf Life!

How Long Can Buttercream Sit Out? Buttercream icing is a favorite for frosting and adorning cakes for any occasion. There are four primary buttercream forms — two meringue variants that utilize just egg whites, French buttercream using egg yolks, and whole egg buttercream. But most bakers now depend on modifications of buttercream’s essential components of butter, sugar, milk, and eggs. In addition, temperature and the ingredients in your buttercream affect how it should be preserved. 


There is nothing like buttercream frosting for simplicity and delicious flavor. It is the most popular cake or cupcake topper, and it is appropriate for every occasion. Whether purchasing something or creating it yourself, knowing how long something will last before going bad is beneficial.

How Long Can Buttercream Sit Out – Buttercream keeps for 2-3 days at room temperature in a covered dish and up to 3 weeks in an airtight container when stored in the refrigerator.

The buttercream will keep in the freezer for about 3 months, whether it is applied to a cake or not.


Buttercream Icing: How Far Ahead Can You Make It?

Many bakers prepare their icing and cake layers ahead of time. Then, when they begin to decorate the cake, all of the hard work is completed, making the process significantly more pleasurable.

If you are not using an item with a limited shelf life, such as milk, you may create this buttercream icing several days ahead of time, sometimes even weeks ahead of time. Check the list of ingredients to see which one has the lowest shelf life and use that one. That is the maximum amount of time you should keep it before it goes bad.


However, I would advise you never to create your frosting more than a week before using it since it will get rancid. In such case, use a high-quality airtight container, such as this one, to keep the food fresher longer. It’s initially intended to hold ice cream, but it also works very well to secure icing.
