What is Buttercream Frosting?

Buttercream frosting is a delicious, sweet icing for cakes, cupcakes, cookies, brownies, and other desserts.

It is made from butter (or margarine), powdered sugar, vanilla extract or flavoring of choice, and sometimes a little bit of milk to make it creamier.

Buttercream frosting can also be flavored with extracts like peppermint oil for candy cane flavor in the winter holidays.

The icing is whipped until light and fluffy before being spread over any dessert item that requires icing on top.

Some people like to whip heavy whipping cream into their butter-based frostings for additional flavor and texture.

Buttercream frosting tastes best when chilled so try refrigerating your cake overnight before decorating with this delicious topping.

How to Store Buttercream Frosting?

You may have noticed that buttercream frosting can be a bit difficult to store because it’s not as stable as other frosting varieties.

This is because buttercream has more fat, making it harder to keep a creamy, smooth texture for long periods.

Therefore, the best way to store your buttercream frosting is by spreading it on cake layers and freezing them until you are ready to use them again.

If this method doesn’t work out well for you, try storing it at room temperature with an airtight lid or container.

Just make sure that there’s no condensation forming inside the container- otherwise, the icing will get soft and watery very quickly.

You may also want to consider purchasing a pastry bag fitted with a large round tip (or any piping set) so that all you have to do is snip off the end of the pack with scissors and start frosting.

You can store these in a freezer or fridge, but it’s best not to put them too close to the door so that they don’t get warm air blowing on them constantly.

It would be best to make sure there are no leaks in your pastry bag before storing because this will cause condensation inside your container, which will significantly affect the shelf lifecast.

The critical thing about buttercream icing can keep it fresh for as long as possible.

If you plan on piping from a cake-decorating set, always use an insulated caddy filled with ice packs when transporting iced cakes.

This way, if anything melts while driving home and gets onto the cake, you can wipe it off.

Many factors will affect the longevity of your icing, including how it is stored and what type you choose.

Buttercream frosting is made with butter, confectioner’s sugar, and vanilla extract.

Generally speaking, though, frozen buttercream will last about three months in the freezer.

It is important to remember that the longer it stays fixed, the more likely ice crystals will form and eventually break down the texture of your buttercream frosting.

The type of icing can also affect how long it lasts: whipped cream topping (like Cool Whip) usually has a shelf life of two weeks to one month when refrigerated.

Most royal icing seems to last up to a month in the fridge before it spoils due to its high sugar content, making iced cookies susceptible to bacteria growth.

How to Tell if Buttercream Frosting is Bad?

how to tell if buttercream frosting is bad

Bad buttercream frosting is easy to spot.

The most obvious sign of a bad batch is lumped in the icing.

When the buttercream is beaten for too long, the fats separate and form clumps, making it difficult to spread evenly.

In addition, the bad frosting should be lumpy when scooped out of a bowl with a spoon.

It may also have an unpleasant smell or taste due to oxidation in the air from improper storage after mixing.

If the buttercream frosting tastes bad, it’s probably a sign that there are too many eggs in the recipe.

This is because as eggs age and oxidize; they develop an unpleasant taste or smell.

Even if you follow all of these rules for making buttercream frosting, some batches may still turn out badly due to improper mixing techniques or insufficiently fresh ingredients, so keep your eyes peeled.

If your buttercream icing has gone bad, there are two solutions: Re-mix it with more cream (or other liquid) if you notice lumps before using.

Otherwise, swap in half of another batch – this will fix both problems as fresh ingredients can help remove any oxidized flavors while making things smoother and easier to work with.


Buttercream frosting is a delicious treat, but it can be difficult to tell if the buttercream has gone bad.

Luckily, there are some easy ways for you to figure out whether or not your buttercream frosting has expired so that you don’t have to eat anything that might make you sick.

All you need to do is store your buttercream frosting properly to stay fresh for as long as possible.
