This Japanese Strawberry Cake is a fluffy sponge filled with fresh strawberries and whipped cream. It’s light, sweet, and simply lovely!
If you ask me, the best part is the sweet strawberry flavor combined with the creamy goodness. Perfect for a special occasion or just because! 🍓
Key Ingredients & Substitutions
Strawberries: Fresh strawberries are key for this cake. For a twist, you could use other berries like raspberries or blueberries, but they won’t provide the same classic flavor.
Cake Flour: This gives a light texture. If you don’t have it, all-purpose flour works too; just add a bit of cornstarch to soften the protein content.
Heavy Cream: Use this for the whipped cream to achieve a rich texture. If you’re looking for a lighter option, try using coconut cream or a non-dairy whipped cream alternative.
Powdered Sugar: This adds sweetness and helps stabilize the whipped cream. Granulated sugar can work in a pinch, but the texture won’t be as smooth.
How Can I Ensure My Sponge Cake is Light and Fluffy?
Getting the sponge cake just right is important for this Japanese Strawberry Cake. Here are steps to help you succeed:
- Whip eggs with sugar until the mixture is thick and pale; it should form ribbons when the beaters lift.
- Gently fold in the cake flour. Use a spatula and a light hand to keep the air in.
- Make sure your butter and milk mixture is cool to avoid cooking the eggs in the batter.
- Don’t overbake! Keep an eye on the cake, and check for doneness a minute or two early if you’re unsure.

How to Make Japanese Strawberry Cake
Ingredients You’ll Need:
For the Sponge Cake:
- 4 large eggs
- 120 g (about 1 cup) granulated sugar
- 100 g (about 3/4 cup) cake flour, sifted
- 30 g (2 tbsp) unsalted butter, melted and cooled
- 2 tbsp milk
- 1 tsp vanilla extract
For the Whipped Cream:
- 300 ml (1 1/4 cups) heavy cream, cold
- 30 g (2 tbsp) powdered sugar
- 1 tsp vanilla extract
For the Filling and Decoration:
- 450 g fresh strawberries, hulled and washed
- Additional fresh strawberries for decoration
- Edible flower decorations (optional)
How Much Time Will You Need?
This recipe takes about 25 minutes to bake the sponge cake, plus an additional 30 minutes for preparation (including making the whipped cream and preparing the strawberries). Finally, you’ll need at least 2 hours for the cake to chill in the refrigerator. So, overall, set aside around 3 hours for this delightful dessert!
Step-by-Step Instructions:
1. Prepare the Sponge Cake:
First, preheat your oven to 170°C (340°F). Grease and line an 8-inch (20 cm) round cake pan with parchment paper to prevent sticking. In a large bowl, beat the eggs with an electric mixer until they become frothy. Gradually add the granulated sugar while continuing to beat until the mixture is thick, pale, and ribbons when you lift the beaters. Gently fold in the sifted cake flour in batches, being careful not to deflate the mixture. In a separate small bowl, mix the melted butter, milk, and vanilla extract, then slowly fold this into the batter. Pour the batter into the prepared pan and smooth it out with a spatula. Bake for about 25 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool completely on a wire rack, and once it’s cool, slice the cake horizontally into two even layers.
2. Prepare the Whipped Cream:
Next, get ready to make the whipped cream! Chill a mixing bowl and beaters in the refrigerator for about 10 minutes. Pour the cold heavy cream into the chilled bowl, and add the powdered sugar and vanilla extract. Beat on medium-high speed until soft peaks form—be careful not to overbeat, or it may become too stiff!
3. Prepare the Strawberries:
Now it’s time for the strawberries! Remove about 12 medium strawberries for decoration, and leave the rest for the filling. Slice the remaining strawberries into halves or quarters, depending on their size, to help layer them nicely in the cake.
4. Assemble the Cake:
To assemble the cake, place the bottom sponge layer on your serving plate. Spread a layer of whipped cream evenly over the sponge. Then, arrange a layer of the sliced strawberries on top of the whipped cream. Add another thin layer of whipped cream over the strawberries to keep them in place. Place the second sponge layer on top. Now, cover the entire cake with a smooth layer of whipped cream. Decorate the top and sides with whole strawberries and pipe more whipped cream for a beautiful finish. If you’d like, you can also add edible flowers for a pop of color!
5. Chill and Serve:
Finally, refrigerate the cake for at least 2 hours before serving. This allows the flavors to meld and the cream to set nicely. When you’re ready, slice carefully and serve chilled. Enjoy your lovely and fresh Japanese Strawberry Cake!
Can I Use Frozen Strawberries Instead of Fresh?
While fresh strawberries are preferred for their flavor and texture, you can use frozen strawberries in a pinch. Just be sure to thaw them completely, drain excess moisture, and pat them dry before using to prevent a soggy cake.
What if I Don’t Have Cake Flour?
No worries! You can make a substitute by using all-purpose flour and removing 2 tablespoons from each cup, then adding 2 tablespoons of cornstarch. This will yield a lighter texture similar to that of cake flour.
How Long Can I Store Leftovers?
Leftover cake can be stored in an airtight container in the fridge for up to 3 days. To maintain the best texture, consider covering the cake to prevent the whipped cream from deflating.
Can I Make This Cake in Advance?
Absolutely! You can prepare the sponge cake a day ahead and store it well-wrapped in the fridge. Assemble the cake with whipped cream and strawberries on the day you plan to serve it for the freshest flavor and appearance.
