Soft and Airy Japanese Strawberry Cake with Fresh Strawberries

This Japanese strawberry cake is all about a delicate sponge that bakes up featherlight and airy, layered with billowy whipped cream and fresh berries. It’s the sort of dessert that feels like a special occasion, but comes together with a few simple steps and no fancy equipment.

The sponge relies on well-whipped eggs for its lift, so you get a tender, moist crumb without creaming a stick of butter. A lofty dome of whipped cream and a crown of strawberries finish it off, making it look like something from a bakery window.

What Makes This Cake So Light and Lovely

The crumb is tender and airy, not dense or sugary. It practically melts, balanced by the cool tang of whipped cream and the bright, juicy pop of real strawberries. Every bite stays fresh, never heavy.

I love that this recipe keeps things simple but still delivers that Japanese patisserie look. The sponge bakes with a flat top that needs almost no carving, so you can stack it right away. It’s my go-to for birthdays or a lazy Sunday project, and it never fails to impress.

Ingredients

• 4 large eggs, at room temperature: the key to a lofty sponge
• 100 g (1/2 cup) granulated sugar: dissolves easily into the eggs
• 100 g (3/4 cup) cake flour: sifted twice for the finest crumb; all-purpose works in a pinch but the texture won’t be as airy
• 20 g (1 1/2 tbsp) unsalted butter, melted: adds a whisper of richness without weighing down the batter
• 1 tbsp whole milk: helps keep the sponge moist
• 1 tsp vanilla extract: rounds out the flavor
• 2 cups (480 ml) heavy cream, cold: for the filling and frosting
• 2 tbsp powdered sugar: sweetens the cream without any grit
• 1 tsp vanilla extract: for the cream
• 1 lb (about 3 cups) fresh strawberries: hulled and sliced, plus a few whole ones for the top

Variations and Substitutions

• Dairy-free cream: whip chilled full-fat coconut cream instead; the frosting will be a little softer but still holds up.
• Flour swap: use 90 g all-purpose flour plus 10 g cornstarch for every 100 g of cake flour to mimic a gluten-free alternative.
• Berry swap: raspberries or mixed berries work beautifully; avoid fruit that releases too much juice or the layers may slide.
• Less sweet: reduce the sugar in the sponge to 80 g and skip the powdered sugar in the cream; the berries carry enough natural sweetness.

How to Make Japanese Strawberry Cake

Step 1: Whip the Eggs and Sugar

Preheat the oven to 350°F (175°C) and line an 8-inch round cake pan with parchment paper. Place the 4 eggs and 100 g sugar in a large heatproof bowl set over a pot of simmering water, whisking constantly until the mixture reaches 105-110°F (40-43°C) and feels warm to the touch, about 2 minutes. Remove from heat, add 1 tsp vanilla, and beat with an electric mixer on high speed for 6 to 8 minutes until the batter triples in volume and falls in thick ribbons when you lift the beaters.

The batter should look pale, fluffy, and leave a trail that sits on the surface for a few seconds before sinking back. If it’s still thin, whip another minute—this step builds all the lift, so don’t rush it.

Step 2: Bake the Sponge

Sift the 100 g cake flour over the egg mixture in three additions, folding gently with a spatula after each until no streaks remain. Drizzle the 20 g melted butter and 1 tbsp milk around the edges of the bowl, then fold just until incorporated—overmixing will deflate the batter. Pour the batter into the prepared pan and smooth the top. Bake on the center rack for 20 to 22 minutes, until the top is golden and springs back when lightly pressed.

The baked sponge will be an even golden dome that settles to a flat top as it cools; a slight shrink is normal. Invert the pan onto a wire rack immediately to prevent steam from collapsing the cake. Let the cake cool completely, still inverted, about 30 minutes.

Step 3: Slice and Prepare the Cake Layers

Once the cake is cool, run a thin knife around the edges and unmold it. Using a long serrated knife, slice the cake horizontally into two even layers. If the top is domed, trim just enough to make it flat, but this recipe usually bakes flat so you may not need to.

You will end up with two light, golden discs that feel like a sponge. Set the prettier layer aside for the top.

Step 4: Beat the Cream

In a chilled bowl, combine the 2 cups cold heavy cream, 2 tbsp powdered sugar, and 1 tsp vanilla. Beat with an electric mixer on medium speed until soft peaks form, about 2 to 3 minutes. Be careful not to overbeat; the cream should be billowy and hold its shape but still look satiny.

You want it spreadable but firm enough to support the top layer. Taste and add a touch more sugar if you like it sweeter, then keep the cream chilled until assembly.

Step 5: Layer and Frost the Cake

Place one cake layer on a serving plate cut-side up. Spread a generous cup of whipped cream evenly over the surface, then arrange a single layer of sliced strawberries, pressing them gently into the cream. Top with the second cake layer, cut-side down. Use the remaining cream to cover the top and sides of the cake, smoothing it with an offset spatula. Don’t worry about making it perfect; a rustic look is charming.

Decorate the top with whole or halved strawberries while the cream is still soft. Chill the cake for at least 30 minutes before slicing so the layers meld. Serve cool, and watch the clean slices reveal neat stripes of cream and berries.

A Few Tips for the Lightest Sponge

• Chill everything for the cream: pop the bowl and beaters in the freezer for 10 minutes before whipping; cold tools help the cream whip faster and stay stable.
• Sift the flour twice: this aerates it and makes the sponge extra tender.
• Spread with a light hand: hold the spatula at a slight angle and use gentle pressure so you don’t tear the delicate cake layers.
• Boost bland berries: if your strawberries lack sweetness, toss the sliced ones with a teaspoon of sugar and let them sit 10 minutes to draw out their juices.

Keeping the Cake Fresh

Refrigerate: store the cake covered in the fridge for up to 3 days. The cream firms up and the sponge stays tender.

Serve: take it out 10 minutes before serving so the sponge softens and the cream mellows slightly.

What to Serve with This Cake

A cup of lightly sweetened matcha or hojicha tea works beautifully; the gentle bitterness cuts through the richness of the cream. For an extra treat, a scoop of vanilla ice cream on the side echoes the cake’s clean flavor while adding another cool, creamy note.

Frequently Asked Questions

Why did my sponge turn out dense?

The most common cause is under-whipping the eggs: the batter must reach a thick, ribbony stage before folding in the flour. Overmixing after adding the flour can also knock out the air.

Can I use frozen strawberries?

Yes, just thaw them completely and pat them dry with paper towels to remove excess moisture. Wet berries make the layers soggy.

What if I don’t have cake flour?

For every 100 g of cake flour, substitute 90 g all-purpose flour plus 10 g cornstarch. Sift them together twice to blend well; the sponge will be slightly less airy but still delicious.

Can I freeze this cake?

You can freeze the unfrosted sponge for up to a month. Wrap it tightly in plastic, then foil. Thaw at room temperature before slicing and assembling.

Notes

For the lightest sponge, use room temperature eggs and avoid opening the oven door during the first 15 minutes. The cake keeps well chilled for up to 3 days; let it sit at room temperature 10 minutes before serving so the sponge relaxes.
