Let’s talk about buttercream!

Does Buttercream Frosting Need to be Refrigerated?

The simple answer to this is no; buttercream frosting does not need to be refrigerated. Unless, of course, you’re dealing with German or French buttercream. Wait, what? Yes, there are different kinds of buttercream. Let’s take a closer look.

Types of Buttercream

There are five kinds of buttercream. However, there are only three ways of making them. That’s why most buttercreams can be left at room temperature while some need to be refrigerated immediately.

American Buttercream

American buttercream is the most popular choice because it is insanely creamy and delightful with a fluffy and smooth texture. It is made with a combination of butter, sugar, milk, and vanilla extract. The high amount of sugar allows American buttercream to be stored in a cool, dry area.

Swiss/Italian Buttercream

Swiss and Italian buttercreams are similar to American buttercream. However, they utilize egg whites. They can still be left at room temperature for several days, though. For concerns about salmonella from egg whites, opt for pasteurized egg whites and follow the recipe closely.

German/French Buttercream

German and French buttercreams are the tricky ones. They are created using egg yolks (and custard for the German version). Since the recipe includes egg yolks, German and French buttercreams must be refrigerated right away.

How Long Does Buttercream Frosting Last at Room Temperature?

If you’re using American, Swiss, or Italian buttercreams, you do not need to store them in the refrigerator immediately. Instead, you can leave buttercream at room temperature for up to three days.

Make sure you’re storing it in a cool and dry area. The buttercream should be placed in an airtight container. The last thing you want is for your buttercream to dry up and get a flaky, difficult to spread texture.

Avoid leaving your buttercream in the heat, too. This can cause the buttercream to melt and be difficult to manage. It can also create the perfect environment for bacteria to grow.

How Long Does Buttercream Last in the Fridge?

If you’re not going to use your buttercream within the three-day period, you will need to stick it in the fridge. Again, keeping it in an airtight container is key to success. When properly stored, buttercream can last up to two weeks in the fridge.

When you are ready to use the buttercream, let it thaw on the counter for at least 15 minutes.

How Long Does Buttercream Last in the Freezer?

If you need even more time than two weeks, you can always opt for the freezer. When properly covered and stored, buttercream can last in the freezer for up to three months.

When you’re ready to use the buttercream, let it thaw overnight in the fridge. Then, set it on the counter for about 15 to 30 minutes so it can return to its creamy and spreadable state once again.

FAQs

Now you know that most buttercream does not need to be refrigerated – at least not right away. If you still have questions about buttercream and storage, then keep reading! Below are a few commonly asked questions you will want to know.

Does cake with buttercream frosting need to be refrigerated?

Nope! A cake covered with buttercream frosting can sit at room temperature for three days. As a bonus, the buttercream will act as an insulator for moisture for a really delicious cake. After three days, the cake can be refrigerated but should be covered to hold in moisture.

Does buttercream frosting with heavy cream need to be refrigerated?

Nope! Buttercream that utilizes heavy cream (or milk or cream) does not need to be refrigerated right away. This is because there is such a small amount that is used. A large amount of sugar will render these ingredients stable for a few days on the counter.

Does buttercream icing harden in the fridge?

It can. That’s why I always suggest covering any type of cake with a cake holder or some type of covering like plastic wrap or aluminum foil. This will ensure that no hardening of the frosting or the cake occurs, even after several days in the fridge.

Does frosting go bad if not refrigerated?

Buttercream frosting will not go bad if left out at room temperature for up to three days, but it’s not the same story for all kinds of frosting. Whipped cream frosting and cream cheese frosting, for example, must be refrigerated immediately, or they will spoil.

How far in advance can I make buttercream frosting?

If you make buttercream frosting and store it in the freezer, you can make it up to three months in advance. Just make sure to thaw it before trying to spread it on your cake. Hard buttercream frosting is not easily spreadable and can ruin your cake!

Final Thoughts

Buttercream is delicious and isn’t too demanding about storage, so you can leave it at room temperature for a few days (unless you’re using French or German buttercream). For longer storage solutions, consider placing them in the fridge for two weeks or freezing them for three months.
