How to store a custom cake

A custom cake is made by hand, shortly before the event, with fresh ingredients and no preservatives. That is what makes its quality, but it also means it must be stored properly. The general rule is simple: as soon as the cake contains a perishable element (cream, fresh fruit, mousse, pastry cream, whipped cream), it keeps in the fridge between 2 and 4 °C.

Conversely, some dry or very sweet preparations can sit at room temperature for a few hours safely. The stakes are not only food safety: they are also texture, moistness and how well the decoration holds. A cake that is too warm sinks, fondant takes on moisture, ganache melts. Properly stored, your cake keeps its look and taste until serving.

If you are unsure about the exact composition of your order, ask the professional through the messaging system: they know their recipe and will tell you the ideal storage.

It all depends on the filling and the coating. Here are the main cases to decide quickly:

• Must be refrigerated: fresh buttercream, cream cheese, mousse, pastry cream, whipped cream, fresh fruit, molten insert, mascarpone.
• Room temperature possible (a few hours): plain sponge, dense chocolate cake, fondant over stabilised ganache, sugar decoration.
• Avoid the cold: a fully fondant-covered design copes poorly with fridge humidity, which can make it sticky. In that case, protect the cake in an airtight box and limit time in the cold.

In practice, most tiered cakes filled with cream must stay chilled. Take them out only for the time needed before serving (see below). If your fridge has strong odours, place the cake in a closed box so it does not absorb them.

How long a cake stays good and safe depends mainly on its filling. Here are indicative benchmarks, kept refrigerated between 2 and 4 °C unless stated otherwise:

These times assume a cake made just before delivery or pickup. Count the baking date, not the receiving date, as the starting point. At the slightest doubt (smell, look, filling left out of the cold for too long), do not take a risk.

Temperature changes everything, for safety as much as for enjoyment. Here are the benchmarks to keep in mind:

A cake served straight from the fridge is firmer and less fragrant: the buttercream is hard and the chocolate masks its aromas. Conversely, left too long in a warm room, it may turn and lose its shape. The right move is to aim for tasting around 18 °C, which means taking it out at the right moment.

This is the step many forget and that makes all the difference. A cake served too cold disappoints, whereas a simple resting time at room temperature reveals all its flavours. Here are the recommended times:

• Ganache or buttercream cake: take out 1 to 2 hours before serving, in a tempered room (away from sun and heat sources).
• Mousse or whipped-cream cake: 20 to 30 minutes is enough; beyond that the filling may break down.
• Fresh-fruit cake: 30 to 45 minutes, just enough to take off the chill without softening the fruit.
• Cheesecake, frozen entremets: follow the professional’s advice; some are eaten almost cold.

In summer or in a warm room, halve these times and keep the cake chilled as long as possible. To slice cleanly, use a large knife dipped in hot water and wiped between each portion: the warm blade glides through the cream without crushing it.

The decoration is often what makes a custom cake unique: sugar flowers, drip, modelling, gilding. A few gestures preserve it:

• Keep the cake in its original box or under a dome, to protect it from knocks and odours.
• When you take it out of the cold, do not remove the lid immediately: let condensation form on the outside of the box rather than on the decoration.
• Avoid placing fresh flowers on cream too far in advance; some are not edible and should be added at the last minute.
• Keep the cake away from heat sources, sunny windows and lit candles before serving.

Condensation is the main enemy of sugar decorations: the droplets that form when a cold cake meets warm air can make colours run or soften fondant. Taking the cake out with the lid closed, then opening it only at serving time, solves most of the problem.

You can freeze some cakes, but not all, and it takes preparation. Plain sponges and unfilled bases freeze very well, up to a month, well wrapped in film then an airtight bag. Fragile fillings (whipped cream, mousse, pastry cream, fresh fruit) cope poorly with freezing: they release water and lose their texture when thawing.

• Freezes well: plain sponge, chocolate cake, undecorated layer-cake base.
• Freezes poorly: sugar decorations, fresh fruit, pastry cream, whipped cream.
• Thawing: always in the fridge, slowly, never at room temperature or in the microwave for a decorated cake.

For a decorated party piece, freezing is rarely a good idea: better to order for the right date. Plan ahead with our guide on ordering lead times, and browse the catalogue to find a professional near you.
