Understanding Swiss Meringue Buttercream

Swiss meringue buttercream is a light, silky frosting made from egg whites, sugar, and butter. It is known for its smooth texture, creamy taste, and ability to hold intricate designs. Unlike traditional buttercream, Swiss meringue buttercream doesn’t crust and remains soft even after refrigeration.

Freezing Cakes: The Basics

Before we delve into freezing cakes with Swiss meringue buttercream, let’s review some essential principles of freezing cakes in general. When done correctly, freezing can help maintain the cake’s freshness and flavor.

To freeze a cake effectively, follow these steps:

  1. Allow the cake to cool completely before freezing.
  2. Wrap the cake tightly in multiple layers of plastic wrap to prevent freezer burn and odors.
  3. Place the wrapped cake in an airtight container or sealable freezer bag.
  4. Label the container with the date and type of cake for easy identification.
  5. Store the cake in the freezer, ideally at temperatures below 0°F (-18°C).

Freezing Cakes with Swiss Meringue Buttercream

Yes, you can freeze a cake with Swiss meringue buttercream! However, there are some important factors to consider to maintain the cake’s quality and the frosting’s texture.

To freeze a cake with Swiss meringue buttercream:

  1. Follow the basic steps for freezing a cake mentioned earlier.
  2. If the cake is frosted, ensure the buttercream is completely set before wrapping.
  3. For added protection, you can place the cake in a sturdy cake box before freezing.
  4. Avoid placing heavy items on top of the cake in the freezer to prevent any damage.

Proper Storage Techniques

Proper storage techniques are crucial to preserve the cake’s taste and texture during freezing. Here are a few additional tips to ensure optimal results:

  1. If the cake is in multiple tiers, consider separating the tiers before freezing to avoid any potential damage during thawing.
  2. Make sure the cake is properly wrapped to prevent air exposure, which can lead to freezer burn.
  3. Use aluminum foil or freezer-safe plastic wrap for an extra layer of protection.
  4. If you have limited freezer space, you can cut the cake into individual slices or portions and freeze them separately.

Thawing and Serving Frozen Cakes

When it’s time to enjoy your frozen cake with Swiss meringue buttercream, proper thawing is essential to maintain its quality and flavor. Follow these steps to thaw and serve a frozen cake with Swiss meringue buttercream:

  1. Transfer the frozen cake from the freezer to the refrigerator. Allow it to thaw slowly overnight or for several hours until completely thawed. Avoid thawing at room temperature, as it can lead to uneven thawing and potential moisture issues.
  2. Once thawed, remove the cake from the refrigerator and let it sit at room temperature for about 30 minutes to an hour. This will help the cake and buttercream soften slightly for easier slicing and serving.
  3. Use a sharp, serrated knife to cut the cake into desired portions. Take care while cutting to maintain the integrity of the buttercream frosting.
  4. Serve the thawed cake at room temperature and enjoy!

Maintaining Cake Quality

To ensure the best quality and taste of a cake with Swiss meringue buttercream after freezing, keep the following points in mind:

  1. It is recommended to freeze the cake without any decorative elements like fondant or delicate sugar decorations. Add these decorations after thawing to maintain their appearance.
  2. Remember that freezing can slightly alter the texture of the buttercream. While the flavor will remain intact, the consistency might become slightly softer. This is normal and should not affect the overall taste.
  3. For optimal results, consume the thawed cake within 2-3 days. The longer it stays frozen, the more the quality may deteriorate.


Can I freeze a cake that has already been sliced?

Yes, you can freeze individual cake slices by wrapping them tightly and storing them in airtight containers or freezer bags.

Can I freeze a cake with other types of frosting?

Yes, cakes with various frostings, such as cream cheese frosting or ganache, can also be frozen following similar guidelines.

Can I freeze a fully decorated cake?

While it’s possible to freeze a fully decorated cake, it’s best to freeze the cake layers and frosting separately. This helps maintain the cake’s visual appeal.

Can I freeze a cake with fresh fruit toppings?

It’s not recommended to freeze cakes with fresh fruit toppings, as the fruit’s texture and appearance may change upon thawing.

Can I freeze a cake for an extended period?

While freezing can help preserve a cake’s quality, it’s generally recommended to consume frozen cakes within 2-3 months for the best taste and texture.


Freezing a cake with Swiss meringue buttercream is indeed possible. By following proper storage techniques, allowing for thorough thawing, and considering the delicate nature of the frosting, you can successfully freeze and enjoy your cake at a later time.

Whether it’s for special occasions or simply to have a sweet treat on hand, freezing cakes with Swiss meringue buttercream offers convenience without compromising taste and quality.
