Who can say no to strawberries and cream? I love making this cake when friends come over. It not only looks beautiful but tastes like a sweet hug on a plate!
Key Ingredients & Substitutions
Eggs: Fresh eggs give the best results for the sponge cake. If you’re vegan or need an egg substitute, try using 1/4 cup of unsweetened applesauce per egg as a binder.
Cake Flour: This flour contributes to the light texture of the cake. If you don’t have cake flour, you can make a substitute by measuring 1 cup of all-purpose flour, removing 2 tablespoons, and adding 2 tablespoons of cornstarch.
Heavy Cream: Using heavy cream is essential for a fluffy whipped cream. If you’re looking for a lighter option, you can use coconut cream instead, just chill it beforehand for best results!
Strawberries: Fresh strawberries are key for flavor. In winter, you might consider using frozen strawberries, but be sure to thaw and drain them well before using.
How Do I Make the Perfect Sponge Cake?
The sponge cake, or Castella, needs special attention to get that light and fluffy result. Follow these steps to ensure success:
- Whisk the eggs and sugar until you see big bubbles and the mixture thickens. This usually takes around 8-10 minutes. It should look light and fluffy.
- When folding in the flour, do it gently! You want to keep the air in the mixture to help it rise.
- Tap the pan to get rid of any air bubbles, but don’t overdo it; just a gentle tap will do.
- Don’t skip the cooling time! This part helps the cake set properly and makes it easier to slice.
How to Make Japanese Strawberry Cake
Ingredients You’ll Need:
For the Sponge Cake (Castella-style):
- 4 large eggs, at room temperature
- 100 grams (1/2 cup) granulated sugar
- 80 grams (2/3 cup) cake flour, sifted
- 20 grams (2 tbsp) unsalted butter, melted and cooled
- 1 tsp vanilla extract (optional)
For the Whipped Cream:
- 450 ml (1 ¾ cup) heavy cream, chilled
- 50 grams (1/4 cup) powdered sugar
- 1 tsp vanilla extract
For the Strawberries:
- 400 grams fresh strawberries
- Additional strawberries for decoration (whole and sliced)
How Much Time Will You Need?
This delicious Japanese Strawberry Cake takes about 20 minutes to prepare, plus 30 minutes in the oven, and at least 2 hours to chill in the fridge. Your total time will be around 2 hours and 50 minutes, but most of it is waiting time for the cooling and chilling!
Step-by-Step Instructions:
1. Prepare the Sponge Cake:
First, set your oven to preheat at 170°C (340°F). Next, line a 6-inch (15 cm) round cake pan with parchment paper so it’s ready for the cake batter. In a large bowl, whisk together the eggs and granulated sugar using an electric mixer on high speed for about 8 to 10 minutes. You want it to triple in volume and look thick enough to form a ribbon when you lift the whisk. Once that’s done, gently fold in the sifted cake flour in three parts using a spatula, being careful not to lose the air you’ve just whipped into the mixture. Slowly drizzle in the melted butter and optional vanilla extract, folding gently until everything is mixed well. Pour the batter into your prepared pan and give it a gentle tap to remove any air bubbles. Bake for 25 to 30 minutes, or until a toothpick comes out clean when inserted into the center. Once baked, let it cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
2. Prepare the Whipped Cream:
While the cake is cooling, let’s make the whipped cream! In a chilled bowl, use an electric mixer to whip the heavy cream together with the vanilla extract until it starts to thicken. Then, gradually add in the powdered sugar and continue whipping until you reach soft peaks. Be careful not to overwhip, or it might turn grainy!
3. Prepare the Strawberries:
Now it’s time to prepare those fresh strawberries! Start by washing and hulling them (removing the green tops and any stems). Slice enough strawberries thinly for layering between the cake layers and keep some whole for decoration. This is where all that juicy strawberry flavor will come from!
4. Assemble the Cake:
Once the sponge cake has completely cooled, get a serrated knife to carefully slice it horizontally into 3 even layers. On a serving plate, place the bottom layer of the cake. Spread a nice, generous layer of whipped cream over it, then arrange your sliced strawberries on top of the cream layer. Repeat this process with the second layer, adding cream and strawberries again. Finally, place the last layer of cake on top. Cover the entire outside of the cake with a smooth layer of whipped cream. You can get creative here! Press sliced strawberries cut side out against the whipped cream on the sides, and pipe decorative swirls of whipped cream on the top. Finish by garnishing with both sliced and whole strawberries.
Lastly, chill your masterpiece in the refrigerator for at least 2 hours before serving. This will let all the flavors come together beautifully! Enjoy your lovely Japanese Strawberry Cake with its light, fluffy texture and delightful fruity taste!
Can I Use Different Types of Fruit?
Absolutely! While strawberries are traditional for this Japanese Strawberry Cake, you can substitute with other fruits like raspberries, blueberries, or sliced peaches. Just make sure they are fresh and complement the whipped cream!
What Can I Substitute for Heavy Cream?
If you’re looking for a lighter option or a dairy-free alternative, you can use a coconut cream that has been chilled overnight. Alternatively, you can try a milk alternative whipped with a stabilizer like gelatin to help it hold its shape.
How Can I Ensure My Sponge Cake is Fluffy?
The key to a fluffy sponge cake is in the egg whisking process. Make sure to whisk the eggs and sugar until the mixture is thick and triples in volume. Be gentle when incorporating the flour to keep that airy texture.
Can I Make This Cake Ahead of Time?
Yes, you can prepare the sponge cake and whipped cream a day in advance! Just store the cake layers in an airtight container and keep the whipped cream in the fridge. Assemble the cake just before serving to keep everything fresh.
