How to store buttercream at room temperature
Thanks to the fat provided by butter and sugar, buttercream can withstand temperatures of up to 25°C (77°F), so it is usually an excellent option to decorate if it is summer or lives in a place with warm weather.
The stability of buttercream is so excellent that it is safe to keep it at room temperature as follows:
- Step 1: Transfer the buttercream to an airtight container.
To prevent contamination, put it inside a container with an airtight lid, which can be plastic or glass.
- Step 2: Store the buttercream in the pantry.
Place the container in your pantry or kitchen, which should be dark, cool, and moisture free. Do not place it near appliances that generate heat.
If you follow these tips, your buttercream can be kept in good condition for two or three days at room temperature.

Now, if you live in an area with temperatures above 77°F (25°C) or the hot season has begun, it is safest to store the buttercream in the refrigerator, especially if you have prepared a considerable amount.
- Step 1: Put the buttercream in an airtight container.
In this case, it is vital that the packaging seals well since buttercream is prone to absorbing the smell and taste of other foods. So a container with a good lid is essential.
- Step 2: Tag.
It will be convenient for you to place a label with the storage date and the product’s name on the container.
- Step 3: Store the buttercream in the fridge.
Put the container in the coldest part and away from foods that emit a strong odor, particularly fish. Although to make sure it doesn’t absorb the smell of other foods as easily, you can cover the container with plastic film.
You can refrigerate the buttercream for up to two weeks. However, experts advise using it in 7 days.
How to freeze buttercream
Can buttercream be frozen? That’s right, and it freezes well, so if you have a lot and don’t want to waste it, the best thing you can do is freeze it.
The instructions for that are the following:

Divide the buttercream into several portions into different bags or freezer containers that are airtight.
- Step 2: Place the buttercream portions in a larger bag.
This way, you add an extra layer of protection against frostbite burns.

Write on the bag the date of storage of the buttercream.
