As bakers, you never want to run out of frosting, especially when decorating your cake. This is where the importance of knowing the proper way of storing your frosting comes in.
Read on and find out the answer to the query “how long does frosting last in the fridge?” and discover how you can store it properly to prolong its usefulness and preserve its quality.
How Long Will Frosting Last in the Fridge?
When kept in the fridge, buttercream frosting can last up to 1 month, whipped cream frosting lasts 4 – 5 days, and cream cheese frosting lasts 1 – 2 weeks.
Factors To Consider
Homemade frosting can last for about a week in the fridge and approximately a month in the freezer.
However, this still depends on what type of frosting you’ll make (buttercream, whipped, cream cheese, etc.) 
Store-bought frostings could last 3 – 4 weeks in the fridge and 2 – 3 months in the freezer. This is ideal if you have a pastry business since this lasts longer than homemade frostings.
The shelf life of your leftovers also depends on the type of frosting you use. This may range from 2 days up to approximately a week.
Store it properly before putting it in the refrigerator, and check for signs of spoilage before using it again.
Buttercream frosting could last in the fridge for about a month, up to 3 months in the freezer, and approximately 2 days at room temperature.
Whipped Cream Frosting
Homemade whipped cream frosting can last up to 2 days. Meanwhile, stored properly in an airtight container, stabilized whipped cream could last from 4 – 5 days.
Cream Cheese Frosting
Cream cheese frosting tends to spoil easily and can only be left at room temperature for about 8 hours. In the fridge, it could last for about 3 days, and up to a month in a freezer.
Swiss Meringue Frosting
Swiss Meringue Frosting can only last up to 3 – 5 days in the fridge and about a week in the freezer. Before reusing, ensure to put it at room temperature and re-whip it before piping.
Storing leftover ganache could prolong its shelf life by up to 2 days at room temperature, 2 weeks in the fridge, and 3 months when frozen .

Also, do not place the frosting near pungent foods such as onions, fish, and meat, as you don’t want them to taste “off”.
Can You Freeze It To Last Longer?
Yes, you can. When properly stored, frosting could last for about a month or more in the freezer. Just remember to put it at room temperature and re-whip it before reusing it.
How Do You Know If Refrigerated Frosting Has Gone Bad?
Some signs that your frosting has gone bad include a pungent smell, a change in flavor or appearance (discoloration), and molds that have started to appear.

How to soften refrigerated frosting?
To soften refrigerated frosting, put it in a metal bowl over hot or warm water until it reaches room temperature. Additionally, you can swirl it regularly to heat it evenly.
Can you get sick from old frosting?
You can’t get sick from eating old frosting unless it’s in the phase of spoilage where molds are already present, it is past its expiration date, or there is a significant change in its appearance.
How long does frosting take to expire?
Frosting can expire within days when left at room temperature, weeks when stored in the fridge, and about a month in the freezer.
Let’s Sum It Up
Storing frosting in the fridge could help extend its shelf life. Just keep in mind the following:
- Transfer leftover frosting to an airtight container and store them properly
