Can You Freeze A Sponge Cake?

This post may contain affiliate links. Please read my disclosure policy.

Baking a light and airy sponge cake from scratch takes time and effort. After spending hours carefully measuring ingredients, whipping egg whites, and gently folding in flour, the last thing you want is for that beautiful cake to go stale after just a few days.

Freezing is a great way to extend the life of a fresh homemade sponge cake so you can enjoy it again later. But can you really freeze sponge cake without ruining the texture?

How Freezing Works With Sponge Cake

Sponge cakes get their signature light and springy texture from beaten eggs incorporated into the batter. When baked, the eggs help give structure to the crumb. Unfortunately, this same delicate structure also makes sponge cakes more prone to drying out in the freezer.

That said, there are steps you can take to successfully freeze sponge cake with minimal impact on texture. Here’s an overview of what happens when you freeze sponge cake:

  • The cold temperature causes the air bubbles whipped into the batter to contract, resulting in a slightly denser texture.
  • Moisture migrates out of the cake over time, leading to some dryness.
  • Sugars and proteins in the cake can crystallize, creating a coarser crumb.
  • Any added fruits or juices may weep a bit, making the cake slightly soggy.

While freezing will inevitably change the cake somewhat, proper storage techniques can minimize texture changes.

Tips for Freezing Sponge Cake

Follow these tips to freeze your sponge cake while preserving as much freshness as possible:

Let It Cool Completely first.

Always allow your sponge cake to cool completely before wrapping it for the freezer. Warm cakes will sweat and become soggy in the freezer. Cooling helps lock structures in place.

Double-wrap in Plastic wrap.

Wrap your cake tightly in two layers of plastic wrap. This prevents ice crystals from forming and stops air from drying out the surface.

Choose An Airtight Freezer bag.

Place the wrapped cake into a high-quality freezer bag. Squeeze out excess air and seal to protect against freezer burn.

Freeze Fast

Get your cake into the freezer as soon as it’s wrapped, ideally within two hours of baking. Quick freezing helps maintain texture.

Thaw in The Fridge

When ready to eat, thaw the sponge cake slowly in the refrigerator overnight. This prevents condensation from making it soggy.

Use Within 3 months.

For best quality, eat your frozen sponge cake within 3 months. The cake may last up to 6 months frozen but will get progressively drier over time.

Best Practices for Freezing Different Types of Sponge Cakes

From classic Victoria sponge to colorful marble cake, the technique for freezing sponge cake is largely the same.

However, a few specific preparations can help maximize the quality of certain popular sponge cake variations.

Classic Sponge Cake

  • Slice the cake horizontally into two or three thinner layers before freezing. This makes it easier to thaw just what you need.
  • Brush simple syrup (equal parts sugar and water boiled together) on cut surfaces to seal in moisture.
  • Avoid adding heavy frostings or glazes before freezing, which can tear the tender crumb. Decorate after thawing instead.

Sponge Cake with Fresh Fruit

  • Berries and stone fruits with a high water content don’t freeze well. They’ll weep juice into the cake. Opt for frozen fruits instead of adding them to the batter.
  • For fresh fruit fillings or toppings, wait to add them until after the cake is thawed.
  • Mix a teaspoon of cornstarch into the juice of any canned fruit filling to prevent excess moisture.

Sponge Cake with Custard or Curd Fillings

  • Custards and curds should be frozen separately from the sponge cake layers. Thaw the filling before assembling and filling the cake.
  • Whipped cream or buttercream frostings will need to be rewhipped after thawing before decorating the cake.

Chocolate or Marble Sponge Cake

  • Wrap the chocolate sponge cake extra securely. Chocolate can absorb odors in the freezer.
  • Allow the marble cake to cool completely before freezing. The chocolate may not set evenly if frozen at room temperature.
  • Expect the chocolate portions of the cake to seem slightly drier after thawing. Cocoa powder is very absorbent.

Sponge Cake with Nuts, Coconut, or Dried Fruit

  • Nuts and dried fruits stay fairly stable when frozen in sponge cake. No special preparation is needed.
  • Shredded coconut may clump together a bit in the freezer. Gently break apart the clumps before serving.
  • Go light on the sugar and sprinkle over any nuts or fruits in the cake batter before baking. The sugars may dissolve or weep a bit when frozen.

Frequently Asked Questions About Freezing Sponge Cake

Freezing sponge cake successfully takes a few extra steps but opens up possibilities for making ahead.

Here are answers to some common questions:

How long does sponge cake last in the freezer?

Properly wrapped sponge cake will maintain its quality when frozen for 2–3 months. It will remain safe to eat for up to 6 months, but the texture will become progressively drier over the full 6 months.

Can you freeze sponge cake before frosting?

Yes, freezing unfrosted sponge cake layers is ideal. The tender crumb can tear easily if frozen after frosting. Decorate with buttercream, ganache, or glaze after thawing instead.

What happens if you freeze sponge cake while it’s still warm?

Sponge cake should always be completely cooled before freezing. Warm cakes will sweat condensation in the freezer, which makes the texture soggy. Rushed freezing can also crack delicate foam structures in the cake.

How do you thaw frozen sponge cake?

Thaw sponge cake slowly in the refrigerator overnight, or for at least 8 hours. Quick thawing leads to condensation, which ruins the texture. Unwrap and serve at room temperature.

Can you freeze baked sponge cake layers with syrup brushed on?

Yes, lightly brushing sugar syrup on sponge cake layers helps seal in moisture before freezing. Just avoid soaking the layers in syrup, which would make them soggy when thawed.

Should you freeze slices of sponge cake or whole cakes?

For convenience, freezing whole cakes wrapped in plastic or foil is ideal. But for smaller households, freezing pre-sliced portions works too. Individual slices thaw more quickly.

Can you refreeze thawed sponge cake?

Refreezing sponge cake is not recommended. The texture will deteriorate significantly with each additional freeze-thaw cycle. Eat any thawed cake within 3-5 days.

Enjoy Your Homemade Sponge Cake later.

With proper freezing and thawing techniques, you can successfully freeze sponge cakes at home to enjoy later with little sacrifice in taste or texture.

Use freezer-friendly fruit fillings, wrap layers securely, and thaw slowly in the fridge for best results. Now you can bake your cake ahead for special occasions or just to have a convenient homemade dessert ready at any time.
