How to store fondant cakes

Tips for storing fondant cakes

You can store fondant cakes at room temperature for 3-4 days if you live in a cool and dry climate and if the filling inside the cake does not need refrigeration. If you have perishable fillings inside the cake, such as fresh fruit, cream or custards, or live in a humid climate you will need to store your fondant cake in the fridge.

Since I usually make bigger cakes and sometimes multiple cakes at a time, I personally store my fondant cakes in a 20°C/68°F air conditioned room. This ensures that all the cakes are kept cool and the climate is dry and I don’t have to worry if it rains. However, I know not everyone can have their air conditioner running all the time. Additionally, sometimes when I only have a small cake to make, I don’t like running the air conditioner for the whole room. It feels a little wasteful. So in those instances, I store my fondant cakes in the fridge.

Storing fondant cakes in the fridge

To store a fondant cake in the fridge, you’ll need to wrap it or box it properly so that the fondant does not come in direct contact with the humidity from the fridge. The main reason fondant cakes sweat in the fridge is because the fridge is full of humidity and that immediately causes the fondant to start condensing. When you remove the fondant cake from the fridge, you also need to allow it to slowly adjust to room temperature before you unwrap the cake. I usually allow an hour for this so make sure you factor this into your time.

My personal experience

When I first started cake decorating I was just told by books and my teachers that fondant cakes were never ever allowed to go into the fridge. So that is what I believed and told my own students for a long time. Until I went to a class one day and saw the teacher storing his cakes in the fridge and wrapping them in big plastic bin bags. I thought it was to protect the cakes from odours in the fridge but he explained to me that wrapping the cakes completely actually protects the cake from condensation in the fridge and prevents it from sweating in the fridge as well as when it comes out of the fridge.

To be honest, I was still a little doubtful but the more I thought about it, the more it makes sense. Fondant is pretty much made up of sugar. Sugar melts if it comes in contact with moisture. It does not melt when it’s cold so the temperature of the fridge is not the thing that is causing the fondant to sweat. However, condensation does occur when there is a drastic temperature change – such as from cold to hot. So if you take the fondant cake out of the cold fridge into a warm room, it will also start sweating. So wrapping the fondant cake helps to insulate the cake from such a drastic temperature change.

If you prevent your cake from sweating, you won’t have to worry about any decorations getting ruined or smudged. For more insights on why fondant can get sticky or sweaty. check my blog post on why fondant sweats.

Can you store fondant cakes in the freezer?

Yes, you can store fondant cakes in the freezer – even if it’s decorated. The same principles as above apply. Make sure the cake is wrapped or boxed well and then allow the cake to slowly acclimatise to room temperature. Due to the freezer’s low temperatures, taking the fondant cake out to room temperature, even if it’s wrapped, will be quite a drastic change. So if you store your fondant cake in the freezer, make sure you transfer it into the fridge the night before. Then take it out to room temperature the next day.

Storing slices of cakes

Once you have cut your cake, storing slices of fondant cake is easy. Simply place the slices of cake in a container or wrap them. You can store them in the fridge for up to a week. I would still let the cake reach room temperature before eating it. That’s because I personally don’t like really cold cake. I find you can’t really taste all the flavours and the texture is not as nice to eat. A slice of cake won’t take long to get to room temperature, so you won’t need to wait long.

You can also freeze slices of fondant cake for up to 6 months. Simply place them into a container or wrapping them up securely.

How to fix condensation on a fondant cake

Depending on how bad the condensation is on your fondant cake, there are a couple of options you can try:

  • Try and use paper towels to blot away any excess moisture so it does not do any more damage.
  • With a light coloured project, try dusting a thin layer of corn flour or icing sugar over the wet areas. This will soak up some of the moisture.
  • Place the project in front of a fan or air conditioner to dry it out. Then wrap it up and place it into the fridge.
  • If the fondant is sweating at room temperature, place it in a closed box or wrap it in a bag. Then place it into the fridge.
  • If the damage is serious, your only option might be to hide the area with some other decorations. Alternatively, remove the moisture damaged portion and redo it.
