Buttercream frosting stays fresh in the fridge for up to a month. Bakers treasure this rich, versatile frosting that creates beautiful swirls and designs to make desserts extra special.
Your homemade buttercream’s shelf life depends on proper storage methods. Airtight containers or piping bags help maintain its freshness. The freezer extends storage time to three months. Recipes that combine butter and shortening can stay at room temperature for two days, though all-butter versions need refrigeration. The perfect consistency comes from keeping buttercream between 70°F and 80°F (21°C to 27°C).

What Affects How Long Buttercream Lasts
Bakers need to know how long their buttercream frosting will stay fresh and usable. Let’s look at what helps you keep the perfect texture and flavor in your creations.
Type of buttercream used
The type of buttercream you choose will change how long it lasts. American buttercream, which uses butter, powdered sugar, and just a bit of liquid, stays fresh longer than other types. You can keep this classic buttercream in the fridge for 1-2 weeks or freeze it for 2-3 months.
Meringue-based buttercreams (Swiss, Italian, and French) have eggs that make them spoil faster. These fancy frostings last about 1-2 weeks in the refrigerator. French buttercream spoils even quicker because it has more eggs, lasting only about a week.
Cream cheese buttercream needs special care. The dairy in this tangy frosting means it won’t last as long – about a week in the fridge. You’ll need to keep most cream cheese buttercreams refrigerated to keep them safe to eat.
Whipped cream frostings are tricky. These light, airy toppings lose their volume quickly and don’t store well.
Ingredients and fat content
The ingredients you use really change how long buttercream lasts. The balance of fat, sugar, and water determines shelf life. Buttercreams with more fat and sugar but less water last much longer.
Sugar plays a vital role in keeping frosting fresh. Room-temperature buttercream needs at least 65% sugar by weight. This much sugar helps stop bacteria from growing and makes the frosting last longer.
Your choice between butter and shortening matters too. All-butter buttercream needs refrigeration, but recipes with shortening or both ingredients can stay out longer. Pure shortening buttercreams stay good at room temperature for up to 2 days.
Adding milk, cream, or cream cheese makes buttercream spoil faster. These ingredients add more water, which bacteria love. That’s why dairy-heavy buttercreams must go straight into the fridge.
Storage method and temperature
The right storage methods help buttercream last longer. Keep your fridge below 40°F. For freezing, aim for -18 to -20 degrees Celsius (-0.4 to -4°F) to keep the texture nice.
Airtight containers are a must. Air makes buttercream crusty and dry, especially if it has lots of sugar. Buttercream also picks up flavors from other foods easily, so keep it away from garlic, fish, or strong cheese.
American or crusting buttercream needs special care. Press plastic wrap right against the surface before sealing the container to prevent crusting. Piping bags work great too – they keep air out and save fridge space.
Label your containers with dates to track freshness. Freeze buttercream in small portions so you can thaw just what you need. This reduces waste and keeps everything fresh.
These tips will help your buttercream stay fresh whether you need it tomorrow or next month.
How Long Does Buttercream Last in the Fridge and Freezer
The secret to making your buttercream frosting last longer lies in proper storage. You’ll always have perfect frosting ready to your next baking project if you know the right timeframes for different storage methods.
Fridge: Up to 1 month for most types
Medium-term buttercream storage works best in the refrigerator. Most buttercream varieties stay fresh and usable for quite a while when you keep them in airtight containers. American buttercream can last up to one month in the fridge. This classic frosting’s texture and flavor hold up really well in cold storage.
All the same, each buttercream type has its own shelf life. Swiss meringue buttercream and other egg-based varieties usually stay fresh about a week in the refrigerator. Cream cheese buttercream needs careful refrigeration and stays good for about 5-7 days.
Your choice of container substantially affects how well the frosting keeps. Airtight containers protect buttercream from exposure to air and stop it from picking up unwanted fridge smells. You can also store buttercream in uncut piping bags with clips or ties – this saves space and keeps the texture just right.
Freezer: Up to 3 months or more
Freezing works amazingly well to store buttercream long-term. Most varieties keep their quality in the freezer up to three months. Some bakers say they’ve stored it successfully even longer – up to four months with proper sealing.
Butter freezes beautifully by itself, so buttercream might last even longer in the freezer than usually recommended. The trick is to keep the container completely airtight to avoid freezer burn and texture changes.
Splitting buttercream into portions before freezing helps a lot. You can thaw just what you need for each project this way. Freezer-safe airtight containers work great, or you can make buttercream mounds wrapped in plastic and stored in freezer bags to prevent freezer burn.
Buttercream stores best at freezer temperatures between -18 to -20 degrees Celsius (-0.4 to -4°F). Steady temperatures help avoid unwanted texture changes during long storage.
Room temperature: When is it safe?
In stark comparison to this, some buttercream types can stay safely at room temperature. Buttercream made with butter and shortening stays food-safe at room temperature up to two days. The high fat content and low moisture make this possible by stopping bacteria from growing.
Pure shortening-based buttercream shows even better stability at room temperature and stays safe unrefrigerated up to two days. But all-butter buttercream recipes need refrigeration since they might melt at room temperature.
Buttercream with eggs, whipped cream, or cream cheese must go in the fridge after sitting out briefly. These ingredients make the frosting more likely to spoil because of their moisture content.
Room temperature buttercream stays fresh when you cover it with plastic wrap or put it in a cake carrier to prevent too much crusting. On top of that, it helps to keep buttercream away from sunlight and heat to maintain its stability.
Professional bakers usually refrigerate decorated cakes if they won’t serve them within three days. Most buttercream-frosted treats stay good at room temperature for 1-2 days before quality starts to drop.
How to Store Buttercream Properly
Your buttercream will stay fresh and delicious longer if you store it the right way. Good storage methods will keep your frosting’s flavor, texture, and quality intact.
Use airtight containers or piping bags
Airtight containers will give a perfect environment to keep buttercream fresh. Push the frosting against the container’s sides to get rid of air bubbles that might affect the texture. American or crusting buttercream needs an extra step – press plastic wrap right on the surface before sealing to keep moisture in.
Many professional bakers prefer piping bags as their go-to storage choice. Just fill your bags with buttercream and seal the ends well before refrigerating. This works great especially when you have big events coming up. You can store the buttercream in bags without tips, then pop them into a second bag with a tip when you’re ready to use it.
Ziplock bags are another excellent option that works well for both refrigeration and freezing. Flattening the buttercream in these bags makes storage easier and thawing quicker. You can also portion your buttercream for different projects this way. Just snip a corner off the bag and squeeze it into your piping bag whenever needed.
Label and date your frosting
This simple step makes a huge difference in staying on top of everything. Clear labels showing the buttercream type and when you made it are crucial. Labels help you track storage time and use the buttercream while it’s still good.
Labels become even more important for frozen buttercream. Finding different flavors or types gets tricky after freezing without proper marking. Bakers often get confused trying to figure out what kind of buttercream they stored when they skip labeling.
Keep away from strong-smelling foods
Buttercream acts like a sponge for other food odors in your fridge. Keep your frosting far from items like garlic, fish, onions, and strong cheeses. The fats in your buttercream attract these smells quickly and can ruin its flavor.
You might want to wrap your container in plastic wrap as extra protection against unwanted smells. If you’re storing a frosted cake in a fridge with meats or fish, wrap the whole cake in plastic to keep those odors out.
Smart organization makes a big difference. Set aside a specific shelf or area in your fridge just for buttercream and baked goods, away from strong-smelling foods. This simple step helps your buttercream keep its pure, intended flavor until you need it.
How to Reuse Stored Buttercream
The perfect decorating results depend on bringing your buttercream back to its original glory after storing it in the fridge or freezer. Your frosting needs attention before use, even with perfect storage conditions.
Thawing from fridge or freezer
The thawing process requires patience. Move your frozen buttercream to the refrigerator a day before you need it. This slow process prevents temperature shock that could harm the texture. A 500g portion of buttercream needs 3-4 hours to thaw in the refrigerator, but leaving it overnight works best.
Room temperature thawing can damage frozen buttercream. Let it sit at room temperature after refrigerator thawing until it becomes flexible and soft. A warm water bath can speed up the process if you’re short on time – just stir occasionally to warm it evenly.
Re-whipping to restore texture
Stored buttercream at room temperature often becomes clumpy with air pockets. The smooth texture returns after beating it for several minutes in a mixer with the paddle attachment. The paddle works better than the whisk because it mixes ingredients without adding extra air.
Cold buttercream needs quick warming. Heat about one-third of it in the microwave using 5-10 second intervals until melted, then blend it back with the cold portion. Buttercream works best between 70°F and 80°F – stay closer to 70°F for piping, or near 80°F for easier spreading.
Fixing separation or curdling
Temperature issues cause separation in stored buttercream. A curdled appearance with butter clumps and liquid means it’s too cold. The solution involves gentle heating:
- Hold the bowl over steaming water until edges start melting
- Warm a metal bowl briefly over a gas flame
- Melt a small portion in the microwave and mix it back in
The buttercream needs chilling for 10-20 minutes in the refrigerator or mixing over an ice bath if it becomes thin or loose from warmth. Scrape down the bowl sides often during chilling since they cool faster than the middle.
Removing air bubbles
Air bubbles often develop in stored buttercream. A food processor with the S-blade attachment works best to “chop” these bubbles away. This step might seem odd after mixing, but it removes air pockets without adding more air.
The bubbles pop satisfyingly when you press and smooth a rubber spatula back and forth through the buttercream. Another option involves microwaving small amounts for a few seconds – just enough to soften without melting – then stirring with a fork. This technique helps right before cake application.
How Long Does Buttercream Cake Last in the Fridge
A cake with buttercream frosting needs proper storage to keep its delicious taste and looks fresh. The buttercream layer adds flavor and acts as a protective shield for the cake inside.
Fully frosted cakes: 3–5 days
Your buttercream-frosted cake will stay fresh for 3-5 days in the refrigerator. The frosting seals in moisture and keeps the cake layers fresh. Plain buttercream can last up to a month in the fridge, but a complete cake needs different care. The frosting helps prevent the cake from drying out in the refrigerator.
American buttercream cakes are special. They can stay at room temperature for about 3 days if they don’t have perishable fillings or toppings like fruit or whipped cream. You can extend their freshness by putting them in the fridge after that.
Storage tips for decorated cakes
The best way to store your decorated buttercream cake starts with a quick 15-20 minute chill uncovered. This makes the frosting firm enough before you cover it. You should then wrap the cake loosely with plastic wrap to keep refrigerator smells away. Stick some toothpicks into the cake to keep the wrap from touching fancy decorations.
Professional bakers often skip covering cakes in the fridge if there aren’t strong-smelling foods nearby. A cake carrier or box offers better protection against drying and odors. After cutting the cake, wrap the exposed parts tightly with plastic wrap to keep them moist.
Freezing frosted cakes safely
Frosted cakes freeze really well with proper handling. Here’s how to freeze your decorated buttercream cake:
- Place the cake in the freezer uncovered for 1-2 hours until the frosting hardens
- Wrap the hardened cake with 2 layers of plastic wrap and add aluminum foil
- Label with date and contents (good for up to 3 months)
To thaw, move the frozen cake to the fridge the night before serving and keep it wrapped. On serving day, take it out of the fridge, remove all wrapping, and let it sit at room temperature for 1-2 hours. This slow thawing stops condensation from forming between the buttercream and cake layers.
Summing it all up
Buttercream frosting is a baker’s most versatile and beloved tool. This piece explores how different buttercreams—from American to Swiss meringue to cream cheese varieties—need specific storage conditions and have different shelf lives. Bakers can now prepare buttercream ahead of time with confidence, knowing their quality and flavor won’t suffer.
The right storage techniques will without doubt keep buttercream’s texture and taste perfect. Your frosting stays fresh and delicious for days or months in airtight containers, sealed piping bags, away from strong-smelling foods. Clear labels help you avoid the frustration of mystery frostings hiding in your refrigerator or freezer.
The process doesn’t end with storage. You need the right temperature and technique to thaw and re-whip stored buttercream. The perfect consistency needs a working temperature between 70°F and 80°F. Your refrigerated or frozen buttercream returns to its original glory with patient thawing and proper re-whipping.
These storage principles work great for fully frosted cakes too. A buttercream coating adds flavor and seals in moisture, which keeps the cake fresh in the refrigerator or freezer.
Professional bakers and home enthusiasts can now plan ahead with ease. Buttercream’s storage capabilities let you prepare in advance and reduce stress during busy seasons or before special events. Your next batch of buttercream will taste just as wonderful days—maybe even months—later with proper storage. A perfect cake deserves perfect buttercream, regardless of when you make it.
