Cake Storage

Cake storage is not the clear-cut process you thought it was, believe me. As a lifelong cake aficionado and fangirl, I thought I knew everything there was to know about cake preparation and storage. But I was wrong.

When I spent about a year working at a famous Washington, D.C., cupcake shop and learning from the experts, I acquired a great deal of knowledge about the less-than-obvious process of successful cake storage.

Below, I shall share my insider knowledge of how to store cakes. I'll dispel the myths, share my secrets, and help you decide on how to best store a cake based on your estimated time of eating.

Why You Shouldn't Refrigerate Your Cake

I always used to refrigerate the cake, probably because we (at least in the U.S.) have been conditioned to believe that all things are kept "fresh" in the refrigerator. For many years, I believed that this was a good practice, not only because one generally puts things in the refrigerator but also because I frequently see cakes displayed in refrigerators and refrigerated cases in many cafes and restaurants.

My entire belief system was turned upside down when I had my first day of work at a famous D.C. cupcake shop. When I asked them how to store some of the cupcakes I was taking home at the end of the night and suggested refrigeration in an airtight container, they looked at me like I had just proposed we cook and eat a newborn baby.

This is because my coworkers and bosses took cake and cupcakes very seriously. And because refrigeration is a dreadful thing to inflict on a perfectly good cake.

Why? Refrigeration dries sponge cakes out. It's that simple.

Even if you refrigerate a cake in a perfectly sealed container and only for a short amount of time, it will dry out. The only time it is appropriate to refrigerate a cake is if it has decorative buttercream icing that is literally melting (and in this case, appearance trumps taste) or if it is not a sponge cake and rather a cheesecake or some sort of mousse that does require refrigeration.

Try to think of sponge cake-like bread. After all, the two things are quite similar. Do you put your bread in the fridge? No. So don't put your cake in the fridge either!

So How Should I Store Cake?

Since refrigeration is out of the question, you might be wondering what your options are. Let me first introduce the two best short-term options:

1. Bake It and Eat It!

Most sponge cakes are at their prime when freshly baked, so if possible, eat cakes the day they are made. If you are going to a bakery to get cake, check with them to see what their advice is regarding timing. Some bakeries—such as the cupcake shop at which I worked—have a very strict policy of baking cakes fresh every day. This is very labor-intensive, but it also means that you'll get the freshest, best cake possible.

If the bakery from which you procure cakes bakes them ahead of time and gives them to you a day later (or, god forbid, two days later), walk away.

If a bakery refrigerates sponge cakes, run away.

The best, freshest cakes are positively irresistible, so storage won't be so much of an issue. They'll be gone before you know it!

2. Store at Room Temperature in an Airtight Container.

If you bake or buy a freshly-baked cake one night with plans to serve it the following day, you should be fine with storing it in its box or in a sealed plastic container in a cool, dark corner of your kitchen counter.

If you want to be particularly diligent about keeping your cake fresh, store it in a positively airtight container. If it came in a nice cardboard box that you don't want to undo, wrap the box in plastic wrap. If you made the cake, seal it in a plastic cake storage container.

Store your cake at room temperature and keep it out of the direct sun and away from any major heat sources that might melt the icing.

Keep your cake boxed on the counter for up to three days.

How Do I Store Cakes for Longer Periods?

A sponge cake can be stored in a sealed, airtight container at room temperature for about three days. I have friends who have nommed on a cake for up to five days.

Freeze for Long-Term Storage.

If you know that you want to serve a cake more than three days after its baking, seal it in an airtight container and freeze it. When you're ready to eat it, let it thaw slowly at room temperature.

Freezing helps seal the moisture in, whereas refrigerating dries things out. The area of any cake that is most negatively impacted by freezing is the icing, as icing does not thaw out looking as perky as it did when it was first applied. That said, freezing results in a far more tasty cake than one that has gone stale and dry—either at room temperature or in a refrigerator.

Sealed containers are best.

Will Cake Mold if Left Out?

If you're worried about cakes getting moldy, don't. I've kept cupcakes around to see what happens to them, and they don't grow mold. They just dry out and harden. They actually become rather cute fossils that make for excellent projectile weapons. Nobody would expect a cupcake to be as hard as a rock, which makes your attack all the more surprising and wonderfully painful.

How to Store Cake With Buttercream Frosting?

A cake iced with buttercream frosting can be stored, at room temperature, for about two days. After that, it does require refrigeration. If you must refrigerate, place the cake in an airtight container.

What About Cheesecake or Mousse Cake?

The high content of dairy in these types of desserts does require refrigeration. Put them in the fridge soon after you're done eating, especially in warm weather.

How to Store a Cake Overnight?

Most cakes will do fine left in the bakery box on the kitchen counter. You can wrap the outside of the box with plastic wrap for extra moisture retention. You can also use an airtight container.
