How to store sponge cake
Let the sponge cool completely, then wrap it tightly in plastic wrap and keep it in the pantry, the fridge, or the freezer. The place you pick sets how long it lasts, from 3 to 7 days in the pantry to 6 months in the freezer.
Leave the sponge in its baking pan until it’s cold, then turn it out carefully, running a knife around the edge first. Keep it away from strong-smelling foods, because a sponge can pick up their smell.
How long does sponge cake last?
By the closest USDA line, sponge cake lasts 3 to 7 days in the pantry, 7 to 10 days in the fridge after opening, and 6 months in the freezer. That line is for commercial cakes and muffins, because FoodKeeper has no sponge cake entry.
Pantry and freezer times count from the day you buy the cake. Fridge time counts from the day you open it.
FoodKeeper gives no time at all for homemade sponge cake. If you baked yours, the commercial times are the nearest guide you have.
| Product | Pantry | Fridge | Freezer |
|---|---|---|---|
| Commercial cakes and muffins | 3 to 7 days | 7 to 10 days after opening | 6 months |
| Frosting or icing | 10 to 12 months | 2 to 3 weeks after opening | Not listed |
How long does sponge cake last in the fridge?
Sponge cake lasts 7 to 10 days in the fridge after opening, going by FoodKeeper’s line for commercial cakes and muffins. That time counts from the day you open the package, and FoodKeeper gives no fridge time for homemade sponge cake.
Wrap the completely cooled sponge in plastic wrap before it goes in, and keep it away from anything strong-smelling.
Can you freeze sponge cake?
Yes, you can freeze sponge cake. The closest USDA line gives commercial cakes and muffins 6 months in the freezer, counted from the day you buy them.
Wrap the sponge tightly in plastic wrap first. Food kept constantly at 0°F (-18°C) stays safe, so the 6 months is a quality time and not a safety limit.
After a long stay, freezer burn can leave grayish-brown, leathery spots where air reached the surface. They make the cake dry but not unsafe, and you can cut them away.
How to thaw frozen sponge cake
Thaw sponge cake slowly in the refrigerator, which the USDA calls the safest way to thaw frozen food. Small items may thaw overnight, and the USDA says never to thaw food on the counter.
How long do frosting and icing last?
Frosting or icing lasts 10 to 12 months in the pantry from the day you buy it, and 2 to 3 weeks in the fridge after opening. FoodKeeper lists it on its own line.
Those are times for the frosting on its own, not for the cake underneath.
When to throw sponge cake out
Throw sponge cake out if it has mold. The USDA’s advice on mold is that moldy bread and baked goods should be thrown out, because porous foods can be contaminated below the surface. Cutting off the visible spot doesn’t remove what you can’t see.
