You’ve just finished decorating a gorgeous cake — the frosting is flawless, the details are crisp, and every swirl and edge is picture-perfect. But then comes the challenge: how do you store it without ruining all that hard work? Whether you’re a home baker preparing a cake a day in advance or a cake seller managing deliveries, knowing how to properly store a frosted cake is crucial. In this guide, we’ll cover the best techniques to preserve your cake’s taste, texture, and appearance — so your creation stays fresh and fabulous until the moment it’s served.
Why Storage Matters
Cakes are delicate. Frosting can melt, colors can fade, decorations can sag, and moisture loss can make your cake dry or sticky. Proper storage doesn’t just protect your cake from external damage — it maintains freshness and flavor while keeping the aesthetic intact.
From buttercream to ganache, whipped cream to fondant, each type of frosting has its own storage requirements. And depending on how far in advance you’re baking, the way you store your cake could make or break the final result.
Short-Term vs. Long-Term Storage
Let’s define the difference:
- Short-term storage (up to 24 hours): The cake will be served the same or next day. Main concern: maintaining appearance.
- Long-term storage (1–5 days): The cake needs to stay fresh while maintaining structure. Main concern: freshness, humidity, and smell absorption.
How to Store Cakes Covered in Buttercream
Buttercream-covered cakes are the most forgiving. Buttercream acts as a barrier, sealing in moisture and protecting the cake underneath.
- Room temperature (up to 24 hours): Store in a cake box or cover with a dome. Keep in a cool, dry area away from sunlight or heat sources.
- Refrigerator (1–3 days): Place the cake in a cake box or airtight container. If using plastic wrap, refrigerate the cake uncovered for 15–20 minutes first to firm the frosting, then wrap loosely.
- Before serving: Let the cake sit at room temperature for 30–60 minutes so the frosting softens and flavors return.
Storage Tips for Cakes With Ganache
Ganache-based frostings (especially dark chocolate) are relatively stable at room temperature.
- Room temperature: Up to 2 days in a cool space.
- Refrigerator: Always chill cakes with milk or white chocolate ganache. Use a cake box to prevent condensation and odor absorption.
- Freezer (for future use): Ganache cakes can be frozen if properly wrapped. First chill until firm, then wrap tightly in plastic wrap and foil.
See our article #34 (Drip Cakes at Home) for more on working with ganache and storing drip-style decorations.
Whipped Cream and Cream Cheese Frosting
These frostings are temperature-sensitive and must be stored in the refrigerator.
- Fridge only: Store in a tall cake box or dome. Avoid plastic wrap directly on the frosting as it will stick.
- Stabilized whipped cream: Lasts longer but still requires refrigeration.
- Shelf life: 2–3 days max. Do not freeze whipped cream cakes — texture will break down.
Fondant-Covered Cakes
Fondant creates a smooth, dry surface that protects the cake — but it’s vulnerable to condensation.
- Room temperature (best): Store in a cardboard cake box in a cool place.
- Refrigerator (if necessary): Only refrigerate if the filling requires it. Wrap the box in plastic wrap and remove only when ready to serve. Allow it to come to room temperature before unwrapping to prevent sweating.

How to Avoid Condensation Ruining Your Cake
When transferring cakes from cold to warm environments (like from fridge to counter), condensation can form on the surface of your frosting.
Tips to reduce sweating:
- Store the cake in a box before refrigerating — the box absorbs moisture and buffers temperature shifts.
- When removing from the fridge, keep the cake inside the box for 30 minutes before opening.
- Never place a cold cake directly into a warm room.
Storing Decorated Cakes with Toppings
If your cake includes toppings like fruit, flowers, or candy, these components may require special care.
- Fresh fruit: Add as close to serving time as possible. Store separately and apply when ready.
- Edible flowers: Keep refrigerated in a sealed container with a damp paper towel. Add to cake at last moment.
- Candy/chocolate: Store cake in a cool, dry place. Humidity can cause blooming or melting.

How to Freeze a Fully Frosted Cake
Sometimes, you need to make cakes well in advance. Freezing is possible with certain frostings like buttercream and ganache.
Steps to freeze a frosted cake:
- Chill the cake uncovered until frosting is firm (about 1–2 hours).
- Wrap gently in plastic wrap and then in foil.
- Label with date and freeze up to 1 month.
Thawing:
- Transfer to the fridge overnight.
- Remove the wrapping and bring to room temperature 1–2 hours before serving.
Cake Boxes vs. Plastic Containers
For frosted cakes, choose cake boxes or cake domes over plastic containers. Why?
- Cardboard boxes allow airflow and reduce moisture buildup.
- Plastic can cause sweating and trap odors.
If transporting cakes, use a tall cake box with a non-slip base and refrigeration if required.
Common Mistakes to Avoid
- Covering warm cakes: Causes steam and softens frosting.
- Using plastic wrap on soft frosting: Destroys details and texture.
- Leaving cakes in open air: Leads to drying and odor absorption.
- Storing in a hot kitchen: Frosting melts, especially in summer.
Final Thoughts
Proper cake storage is just as important as baking and decorating. Whether you’re keeping it fresh for family or presenting it to a client, knowing how to protect your cake from temperature changes, moisture, and damage ensures your creation stays perfect until the last slice.
