Light and Airy Strawberry Sponge Cake
This light and airy strawberry sponge cake is the kind of dessert that makes you look forward to berry season all year. It’s simple, fresh, and built around real ingredients.
You get tender vanilla sponge layers, billowy whipped cream, and juicy sliced strawberries. No fancy equipment, no complicated steps, just a cake that tastes like a sunny afternoon.
Why This Sponge Cake Works
The sponge itself is the real star here. It comes out so soft and plush that it soaks up the cream and strawberry juices without turning soggy.
The strawberries are kept fresh, not cooked, so every bite pops with that bright, sweet-tart flavor. Paired with barely sweetened cream, the whole thing feels light, even on the third slice.
Ingredients
- 4 large eggs, room temperature: essential for a lofty sponge that holds air
- 3/4 cup (150g) granulated sugar: adds sweetness and helps stabilize the foam
- 1 cup (125g) all-purpose flour: spooned and leveled, not scooped
- 1/4 cup (30g) cornstarch: makes the crumb extra tender
- 1 teaspoon baking powder: lifts the cake gently
- 1/4 teaspoon fine sea salt: balances the sweetness
- 2 tablespoons unsalted butter, melted and slightly cooled: for richness
- 1 teaspoon vanilla extract: use pure vanilla for the best flavor
- 2 cups (480ml) heavy whipping cream, cold: key to billowy whipped cream
- 2 tablespoons powdered sugar: sweetens the cream lightly
- 1 teaspoon vanilla extract: for the cream
- 1 pound (450g) fresh strawberries: hulled and sliced, plus a few whole ones for the top
Variations / Substitutions
- Dairy-free: swap the heavy cream for well-chilled full-fat coconut cream and use a neutral oil instead of melted butter.
- Mixed berries: replace half the strawberries with raspberries or sliced peaches for a different summer spin.
- Lemon twist: add 1 teaspoon lemon zest to the sponge batter and a little to the cream for a bright lift.
- Jam layer: spread a thin coat of strawberry jam over the bottom sponge before adding the cream for extra fruitiness.

How to Make Light and Airy Strawberry Sponge Cake
Step 1: Whip the Eggs and Sugar
Preheat the oven to 350°F (175°C). Line the bottom of an 8‑inch round cake pan with parchment and leave the sides ungreased, which helps the sponge climb. Place the 4 room‑temperature eggs and 3/4 cup sugar in a large bowl or stand mixer. Whip on high speed until the mixture is very thick, pale, and nearly tripled in volume, about 5 to 7 minutes.
The eggs should reach the ribbon stage. When you lift the whisk, the batter falls in a thick ribbon that sits on the surface for a few seconds before sinking back in. That volume is what gives the sponge its airy structure, so take your time here.
Step 2: Fold in the Dry Ingredients
Sift together the 1 cup flour, 1/4 cup cornstarch, 1 teaspoon baking powder, and 1/4 teaspoon salt. Sprinkle the dry mix over the whipped eggs in three additions, folding gently with a large spatula after each one until just combined. After the last addition, drizzle the 2 tablespoons melted butter and 1 teaspoon vanilla around the edge of the bowl and fold one more time until no streaks remain.
Use a light, cutting motion rather than stirring. The batter will lose some volume, but you want to keep as much air as possible. It should look fluffy and still hold a soft shape when you finish.
Step 3: Bake the Sponge
Pour the batter into the prepared pan and gently smooth the top. Bake on the center rack for 20 to 25 minutes, until the top is golden and the cake springs back when pressed lightly in the center. A toothpick inserted in the middle should come out clean.
Let the cake cool in the pan for 10 minutes, then run a thin knife around the edge and turn it out onto a wire rack. Cool completely before slicing, which takes about an hour. The sponge is delicate when warm, so wait until it is fully cool to handle.
Step 4: Beat the Cream
In a chilled bowl, combine the 2 cups cold heavy cream, 2 tablespoons powdered sugar, and 1 teaspoon vanilla. Beat on medium‑high speed just until soft peaks form. The cream should hold its shape when you lift the beaters but still look smooth and silky.
Stop before it gets stiff and grainy. A slightly soft whip stays light and melds nicely with the strawberries rather than sitting heavily on the cake.
Step 5: Layer and Finish the Cake
Use a long serrated knife to slice the cooled sponge horizontally into two even layers. Place the bottom layer on a serving plate. Spread half the whipped cream over it, arrange half the sliced strawberries on top, then gently press with the second sponge layer. Spread the remaining cream on top and pile on the rest of the sliced berries, leaving a few whole ones with their greens for the center.
Slice and serve right away, or chill up to 2 hours before serving. The cream will be soft, the berries juicy, and the sponge light as a cloud.
A Few Tips for the Airy Sponge
- Room‑temperature eggs whip up with much more volume, so set them on the counter at least an hour before you start.
- Always fold with a light hand. Overmixing is the fastest way to lose the air you just worked to build.
- Cool the sponge completely before you cut it. A warm cake will compress and tear under the knife.
- Choose ripe, in‑season strawberries. Their natural sweetness and perfume carry the whole cake.
Bake times by pan size:
| Pan size | Bake time (minutes) |
|---|---|
| 8‑inch round | 22 to 25 |
| 9‑inch round | 20 to 22 |
| 8‑inch square | 20 to 23 |
Storing Leftover Cake
- Refrigerate: cover assembled cake loosely with plastic wrap or store in an airtight container. It keeps reasonably well for up to 2 days, though the sponge will soften slightly.
- Serve cold: this cake tastes best straight from the fridge, no reheating needed. The cream firms up a little, and the flavors stay bright.
Frequently Asked Questions
Can I use frozen strawberries?
Yes, but thaw them completely and pat them very dry with paper towels. Excess moisture will make the cream run and the cake soggy.
Can I make the sponge ahead of time?
Absolutely. Bake and cool the sponge, then wrap it tightly and keep it at room temperature for up to a day. Assemble with cream and berries the day you plan to serve it.
Why did my sponge sink in the middle?
It was likely underbaked or the oven door was opened too early. An underbaked sponge does not have enough structure to stay tall once it cools. Let it bake until a toothpick comes out clean and resist the urge to peek before the 20‑minute mark.
Can I use whipped topping instead of heavy cream?
You can, but it will taste sweeter and a little less rich. A stabilized whipped cream made from heavy cream gives the cleanest, freshest flavor against the strawberries.
